How to connect the old hard


Hello dear readers of my blog.

Today we will talk with you about how to connect the ide hard drive to the sata connector in the motherboard. There will be no particular difficulties in this topic, and by reading which you can solve existing problems.

So, I will analyze this topic on the example of my recent discussion with a friend who asked me to help with updating the stuffing of the computer. The following question arose: what to do if it is necessary to connect an old HDD with an IDE connector to the new motherboard, where there are only new SATA connectors.

The question was somewhat different, it was necessary to gain access to the information that was stored there. And it was urgent to solve this problem. It is worth noting that this was not the first time that I was asked to connect an old hard drive to a new motherboard, which is why I decided to show everyone my method. Below are the differences between these connectors.

Connection to a computer (inside the system unit)

SATA cable due to its shape is more resistant to multiple connections. The SATA power cord is also designed with multiple connections in mind. The SATA power connector provides 3 power supply voltages: +12 V, +5 V and +3.3 V, however, modern devices can operate without a voltage of +3.3 V, which makes it possible to use a passive adapter from the standard IDE to SATA power connector. A number of SATA devices come with two power connectors: SATA and Molex.

The SATA standard abandoned the traditional PATA connection of two devices per cable, each device relies on a separate cable, which eliminates the problem of the impossibility of simultaneous operation of devices on the same cable (and delays resulting from this), reduces possible assembly problems (Slave / Master conflict problem devices for SATA is missing), eliminates the possibility of errors when using non-terminated PATA cables.

The SATA standard supports the command queue function (NCQ starting with SATA Revision 2.x).

The SATA standard does not provide for hot swapping of the active device (used by the Operating System) (up to SATA Revision 3.x), additionally connected drives must be disconnected gradually - power, a loop, and connected in the reverse order - a loop, power.

SATA devices use two connectors: 7-pin (data bus connection) and 15-pin (power connection). The SATA standard provides the ability to use the standard 4-pin Molex connector instead of the 15-pin power connector. Using both types of power connectors at the same time can damage the device.

The SATA interface has two data transfer channels, from controller to device and from device to controller. LVDS technology is used for signal transmission, the wires of each pair are shielded twisted pairs.

There is also a 13-pin combo SATA connector used in servers, mobile and portable devices for slim CD / DVD drives. Devices are connected using a SATA Slimline ALL-in-One Cable. The combined connector consists of a 7-pin connector for connecting a data bus and a 6-pin connector for connecting power to the device. In addition, a special adapter is used in the servers to connect to these devices.


Most interesting comments on the colors of the SATA power connector cable:

RU2012: “There are adapters for converting the 4-pin Molex connectors to SATA power connectors. However, since the 4-pin Molex connectors do not provide 3.3 V, these adapters provide only 5 V and 12 V power and leave 3.3 V lines disconnected. This does not allow the use of such adapters with drives that require power to 3.3 V - orange wire.

Understanding this, hard drive manufacturers have largely abandoned the support for the 3.3 V orange power cable option in their storage devices - the line power is not used in most devices.

To comment, just ask a question in the window below, then click "Post as" - drive in the email and Name, and click "Post comment".

In the case of the system unit there are compartments for devices (usually they are in the front of the case). The upper compartments of the casing are intended, as a rule, for the installation of optical CD / DVD, Blu-ray drives. And the lower compartments shown in the photo are designed to install hard drives.

From the available bays, we select any and put a hard drive there. It is necessary to arrange it so that the connectors (see image) of the disk look inside the case.

Then, we take the hard drive and insert it along the guides, which do not let it fall down.

Everything. The disk is inserted, now it needs to be fixed with screws. As you can see, there are corresponding mounting holes on the case.

It is necessary to make sure that the threaded holes on the disk coincide with the holes on the case. Now we will tighten the screws in them.

It is desirable that there are four screws, two on one side and two on the other. Having screwed the hard drive on one side, we deploy the case and fasten the other side.

We fixed the hard drive. Check that it does not stagger, if the disk moves, then tighten the screws harder.

Hard disk installation is complete, now it can be connected to the motherboard. First of all, it should be noted that hard drives of different generations have different connectors, different cables ("loops") for connection.
We will consider connecting a hard drive with the most common IDE (obsolete, but still in use) and SATA interfaces.

Connecting a SATA Hard Drive

Connecting a hard drive to a laptop or computer is not a very difficult task, however, those who have never encountered this may not know how to do it. In this article I will try.

The task of transferring various data from the old drive may arise for each user. However, this is not always easy to do: support for outdated methods of transmitting information is absent on most modern personal computers. In addition, the connection method is highly dependent on the type of hard drive itself. About how to connect an old hard drive to a computer of a modern generation, we will tell in this article in Russian.

Before connecting the old hard drive to the computer, it is necessary to determine the type of connection used on the storage medium and prepare the PC for adding a new component. At this stage, you may need to purchase and install additional hardware.

A Winchester, released five to 20 years ago, can have one of several interfaces (that is, communication methods):

Presented in 2003 and is the most common way to connect hard drives to date (the latest version was presented in 2013). SATA, whose current revision is numbered 3.2, is a backward compatible standard: this means that even devices of a decade ago can be connected to modern controller implementations. SATA uses a small 7-pin data connector and 15-pin for current supply.

It was released in 1986. It was widely distributed in the 1990s, the last change in the standard was made in 2003. The interface is the most common on hard drives released over the past two decades. Externally, the connector of this standard looks like a 40-pin connector (two rows of 20 contacts). In most cases, one of the contacts is removed in the same row: when paired, with the appropriate cable (in which there is no one hole), this avoids an incorrect connection. Another similar protection is a groove on one of the sides of the socket: in the same place on the plug of the connecting cable is a ledge.

SCSI, like the IDE, was introduced in 1986. It was rarely used in the consumer segment, since it was mainly oriented to use as part of server equipment. Currently, components connected via SCSI are extremely rare.

The ATA (IDE), SATA, and SCSI connectors are not compatible with each other, so a visual inspection is enough to determine the media interface. To clarify the revision of the standard, you must refer to the device passport.

Step 2: preparing the computer to connect the old hard drive

Not every modern PC is equipped with the necessary set of technical tools necessary to connect any component released in the past. As a rule, manufacturers either cease to support obsolete standards altogether or leave their support optional (they are used on a limited list of models, they offer to buy additional modules, etc.). Before you connect the old hard drive to your computer, you may need to purchase additional hardware. The need for their application depends on several factors. First of all, from the HDD interface and the motherboard model.

2.1. Preparing a PC to connect a SATA drive

Despite the fact that the history of SATA has been around for 13 years, this interface is relevant and is supported by any modern motherboard. Since all the necessary technical means for using an HDD with this interface are already included in the PC, only a SATA cable is required. Such a cord can be taken from the motherboard kit or purchased separately. System preparation is reduced to turning off the power and removing the housing cover.

2.2. Preparing a PC to connect an ATA (IDE) drive

Over the past few years, the number of motherboards supporting this standard has dropped dramatically. This means that in order to connect the old hard drive to a new generation computer, you may need to purchase an additional device - an external adapter.

In order to understand whether your motherboard supports this interface, you need to refer to the device manual. Another quick way is a visual inspection: the presence of a 40-pin connector means that the board nominally supports this type of connection.

If the motherboard has an ATA (IDE) connector, then before you connect the old hard drive to the computer, it is enough to get the appropriate cable (usually comes with the motherboard). Otherwise, you need to buy an additional component - the ATA controller (IDE).

Adapters for connecting legacy media can be made in two versions: for the PCI-e bus (installed inside the PC) and USB (an external module that connects to the USB port). Each of them has its advantages and disadvantages.

The device is a small expansion card, which is installed in the PCI-e port located on the motherboard. Examples of models: JMicron JMB363, Espada FG-EST04A-1-CT01. The average price is about 1,500 rubles.

- does not require an additional power source for the drive,

- convenient for constant use, because it is installed inside and does not take up space on the desktop,

- The data transfer speed is higher than that of external USB adapters.

- application is possible only on stationary computers, while the form factor also plays a role: on monoblocks or no-tops, installation is usually impossible,

- it is necessary to disassemble the PC case.

Such devices are an external adapter, one end of which is connected to the USB port of the PC, and the other to the HDD. Power for the hard drive is supplied through an external power supply. Examples of models: AGESTAR FUBCP, Aopen USB - IDE. Cost - about 1000 rubles.

- can be used on form factors in which installing devices inside the case is fundamentally impossible: on laptops, all-in-ones, no-tops,

- there is no need to disassemble the PC case,

- some models are multifunctional, and also support SATA,

- for the drive requires a separate power supply (usually comes with an adapter),

- low data transfer rate, since USB 2.0 is used.

Preparing a PC whose motherboard does not have an IDE connector for connecting the appropriate drive consists in purchasing an external adapter and installing it. You may need to install additional software (drivers). The process of pairing a PC and an external controller depends on the device model and is described in detail in the user manual.

2.3. Preparing a PC to connect a SCSI drive

Even being relevant, the SCSI interface was not widespread in the field of domestic use, since only server equipment was equipped with the appropriate controller. Therefore, you can connect an old SCSI hard drive to a computer only using special controllers.

As in the case of ATA, SCSI adapters can be implemented as embedded devices for PCI-e (for example, Adaptec 2248700-R U320), or for USB (Adaptec USBXchange), while all the advantages and disadvantages remain. However, unlike similar ATA components, SCSI controllers are less common and usually cost more.

Step 3: attaching the old hard drive to the computer

At this point, your PC should be prepared to connect the drive. This means that, firstly, you must have all the necessary connecting cords, and secondly, make sure that you have the appropriate controller in the system (or connect it and install the software for it to work).

Make sure the power supply is unplugged. Then you need to connect the power and data cords to the drive. Turn on the PC: if the connection was made correctly, the hard drive must be determined by the operating system.

We are often sent letters asking how to connect an ancient hard drive with an IDE interface to a modern computer that does not have outdated connectors, or even to a laptop.

Everything is extremely simple. Two options are possible.

Permanent connection of an IDE hard drive to the motherboard.

This is done through the appropriate adapter, which is not very expensive, but finding it on sale is not so simple. The drive is installed inside the system unit as usual and connected using SATA (power and data). But, frankly, putting an old device into a modern computer is not rational. It will make noise and crackle heads, and in addition, its speed will be far from the best. Even the weakest modern hard drive will outperform it in speed with a large margin. It is much more convenient to rewrite all its contents to a new and more capacious model with SATA interface.

IDE SATA adapter

Closed housing adapter. Otherwise, it is no different from the previous model

Temporary connection of an IDE hard drive using a USB adapter

This option is preferable. Owners of desktops will not have to remove the cover of the system unit, and owners of laptops can’t do without it at all. A USB adapter is bought for connecting IDE hard drives of 2.5 and 3.5 inches form factors. Unfortunately, fewer and fewer are on sale.

But be careful, you can confuse and buy an adapter only for the SATA hard drive, of which most are now. In addition, the docking stations will not be useless, they mainly allow you to connect only hard drives with SATA interface.

The most versatile adapter from AgeStar. You can connect any model of hard drives. In addition, such an adapter can connect an optical CD-ROM and DVD-ROM drive with an IDE interface to a netbook

However, there is one caveat. The speed of the drive in the first solution will be maximum, since the device connects directly to the motherboard, and in the second case it will be limited by the USB 2.0 bandwidth (480 Mbps) - in practice, the speed reaches a maximum of 24-26 MB / s, and even that not always. All adapters with a more advanced USB 3.0 bus allow you to connect only SATA-drives.

My advice is this. Use USB adapters, but as soon as possible dump data on a more modern disk and abandon the old IDE standard.

Installing a hard drive on a computer is not a difficult task and there is nothing to be scared if you have to do it yourself, even if you have never seen your computer in open form. I’ll explain everything to you now, and you will succeed.

Installing a hard drive on a computer will be required if you are going to update your device, build a computer from scratch, or want a second HDD. This instruction will help you in the first two cases. But in the case of replacing the HDD, I will not tell you how to remove the old one, I think there will be no problems with this, but I will only show how to correctly install the new one. But about connecting a second hard, I’ll tell you some other time.

Installing a new hard drive begins by screwing it to the chassis. This is done with bolts. There are threaded holes in the hard case, there are grooves in the computer case. Through them and screwed.

Убедитесь, что установленное устройство не помешает вентиляции внутри системного блока, а также что все провода и шлейфы спокойно дотягиваются до него без натяжки.

Подключение жёсткого диска к материнской плате

Болты зафиксированы, и переходим к проводам и шлейфам. Connect with which the HDD will communicate with it.

Depending on the type of HDD, they will differ - ATA (IDE) and SATA. The first ones are older, the second ones are new, but both types are still on sale.

The IDE hard drive is connected to the motherboard using a cable, which is characterized by a large number of contacts, pins, and therefore it is wide. There is a lock on the cable that does not allow you to connect it incorrectly. Therefore, it is impossible to make a mistake. Connect the IDE cable of the HDD and the motherboard.

The SATA hard drive is connected using a narrow cable. It will not be possible to mix up the connection sockets on the motherboard, since SATA will only fit into the correct connector. Using a SATA cable, you should connect the HDD to the motherboard.

Connect the hard drive to power

In IDE and SATA hard drives, power cables are different. Most are for one and the other type or there are special adapters.

To connect IDE hard drives, use the 4-pin Peripheral Power Connector. SATA drives require a SATA Power Connector. In both cases, you can not mix up the connections, so do not be afraid that you will do something wrong.

Differences in connecting IDE and SATA hard drives

It would seem that the connection procedure is the same, but in fact the IDE is slightly different from SATA in that it requires you to set the jumper position, the so-called jumper.

The motherboard is usually supplied with a pair of connectors for IDE devices, and two devices can be connected to each. Each pair can have one master device and one slave, and it is impossible that there are two identical ones. The hard drive must be in the master position if Windows boots from it. The second device in the same connection branch must be a slave.

If all this is difficult to understand, then just put the jumper on master, if your computer has only one hard drive.

You can find the jumper connection card on the hard drive case itself.

There are no such problems with SATA. Master and slave positions are set via the BIOS. When connecting a SATA hard drive, you will need to configure it as bootable if it has an operating system installed.

When the first computers appeared, all programs, games and other files practically did not take up disk space. Now things are very different, and often you have to install an additional storage medium. Therefore, each user should know how to connect a second hard drive to a computer. In fact, this is not difficult to do, just follow a simple instruction.

First, the device must be purchased at the store. Please note that the hard disk has several connection interfaces. After purchasing, you can proceed to install the device.

Preparation for installation

  • How many hard drives are already connected to the motherboard? Most often, a computer has only one hard drive, so installing a second drive is not difficult. In most cases, the HDD is located directly under the DVD-ROM, so finding it is not difficult,
  • Is there additional space for installing a second hard drive? In the event that it is not possible to install a second or third drive, then you will have to purchase a USB drive,
  • What type of cable is used to connect a hard drive to a computer? If the purchased device will not have the same interface as on the PC, it will be difficult to install it.

It should be noted that you will need a 3.5-inch hard drive. Small disks designed for laptops do not need to be bought.

Physical drive connection

If the system unit has not yet been disassembled, disassemble it. Now it is recommended to get rid of static electricity. This is done by any means known to you. If desired, you can purchase a special grounding bracelet in the store.

After minor manipulations, the hard drive will be fixed in the case, now it remains only to connect the hard drive. Before you turn on the power cable and cable, it should be noted that for the IDE and SATA interface, the procedure is slightly different.

IDE Interface

When connecting a disk with an IDE interface, it is recommended to pay attention to such a nuance as setting the operating mode:

If you are installing an additional hard drive, then you must enable Slave mode. To do this, use the jumper (jumper), which is installed in second place. The first row includes Master mode. It is important to note that on modern computers, the jumper can be completely removed. The system will automatically detect which hard master.

In the next step, you need to connect the second or third hard drive to the "mother". For this, the IDE interface is connected to the loop (wide, thin wire). The second end of the cable is connected to the IDE 1 Secondary socket (the main drive is connected to the zero socket).

The final stage of the connection is the power supply. For this, a white chip with four wires is connected to the corresponding connector. Wires go directly from the power supply (box with wires and fan).

SATA Interface

Unlike the IDE, the SATA drive has two L-shaped connectors. One is for power, and the other is for a data cable. It should be noted that such a hard drive lacks a jumper.

The data cable connects to a narrow connector. The other end is connected to a special connector. Most often, there are 4 such ports on the motherboard, but there are an exception of only 2 ports. One of the slots may be occupied by a DVD drive.

There are times when a drive with a SATA interface was purchased, but no such connectors were found on the motherboard. In this case, it is recommended to additionally purchase a SATA controller, which is installed in the PCI slot.

The next step is to connect the power. L-shaped wide cable connects to the corresponding connector. If the drive has an additional power connector (IDE interface), just use one of the connectors. This completes the physical connection of the hard drive.

SSD or HDD - which drive to connect to a PC?

If you updated your PC a long time ago, then the best solution would be to install a modern SSD to speed up the system. An additional SSD drive must be used to install the OS and application programs, which will speed up the computer, reduce the launch time of applications. If you do not have enough 300-500GB of space, then an SSD is not practical to use for storing audio and video files. Good old HDD will come to the rescue, and at a cost it is several times cheaper than SSD.

Ways to connect a new HDD to a PC

Old HDDs were equipped with an IDE interface for connecting to a PC. Now IDE connectors are not used, and have given way to modern SATA. All modern computer motherboards are equipped with several SATA connectors for connecting a new hard drive. To install a hard drive in a computer, 2 cables are used - a data cable and a power cable.

Power for the new hard drive

All modern power supplies have power connectors for HDD or SSD with SATA interface. If your power supply does not have a suitable connector, then you can buy a power adapter from Molex (for IDE) to Sata to connect a new one.

New Hard Drive Data Cable

IDE and Sata drives use various types of data cables. Old-style IDE hard drives connect with a wide cable, and SATA drives use a thin SATA-Data cable. It is impossible to confuse them and you cannot connect an IDE drive to a computer with a Sata cable.

Installing a new hard drive on a desktop computer

To install a new hard drive you will need:

  1. The new drive itself.
  2. Power cable from the power supply (or Molex-Sata power adapter).
  3. Data cable.
  4. A free connector on the motherboard.
  5. 2-4 bolts for fixing the hard drive in the system unit compartment.

The procedure for connecting a hard drive to a computer

First, install the new hard drive in a special compartment in the system unit. We fasten with bolts, connect the data and power cable. After that, turn on the power of the computer and load the PC. In some cases, the new hard drive may be identified as the main one and the computer will try to boot from it. You will receive an error message (since the operating system is not installed on the new disk). In this case, it is necessary to change the priority and boot order from the hard disks in the BIOS. After loading Windows, a new disk will be detected automatically. but to use it, you need to create partitions on it, format them in a suitable file system - NTFS or FAT32.

How to connect sata hdd to ide
Just in case, we immediately point out external differences. IDE - also known as ATA - Advanced Technology Attachment and later PATA - the standard interface for connecting hard drives and PC drives, was popular in the 90s and early 2000s. It is a wide, 40-pin cable. SATA (Serial ATA), which later supplanted its standard, became popular by the mid-2000s and is still relevant today, much more tiny - 7 contacts versus 40.
With the passage of time and the evolution of progress in the market, new, high-speed interfaces displace the old ones, and inevitably there is a compatibility problem - is it worth carrying a HDD that is incompatible with the modern system by default? Or vice versa - if there is no SATA controller on the outdated motherboard (this interface is the standard at the moment), and a forty-pin screw with a 80-pin cable has ordered a long life, you will be surprised to find that you cannot find such a rarity in the nearest computer store , and the machine should still work ... Only how to make friends with a relatively new sata hdd to ide? We will try to answer these questions.
How to connect SATA HDD to IDE?
The solution to both problems lies on the surface - it is very difficult to find a HDD with an old interface in a store, but a controller that makes it easy to get almost any brand new hard drive to work on an old system is complete! As a rule, this is a small microcircuit, on one side of which there is an output for an IDE cable (a 40-pin wire is plugged into the corresponding output on the motherboard and into the controller), and on the other, SATA (connects directly to the hard drive) and 4-pin power ( comes from the PC power supply).
Nuances and disadvantages
It should be borne in mind that if you have seen a computer, then with a high degree of probability the power supply unit is also old - and the power supply for the SATA hard disk differs in some cases from that of the IDE (i.e. not MOLEX) - either a new unit, or another adapter (it’s not difficult to find one, but its price is pretty cheap).

There is one more obvious minus in this approach - if the hard drive is SATA-based and takes advantage of this interface, then when connected via the old bus, the speed will be noticeably limited: even the very first revision of Serial ATA gives in theory from 150 mb / s against 133 for IDE, and in bandwidth, the difference is several times not in favor of an outdated port. And so you can connect at least an SSD to the old system, but the higher the speed indicators of the connected media - the more noticeable will be the loss in speed.
Also, do not forget that old hardware often has an outdated operating system, which may not support partitions larger than 2 TB or even the NTFS file system. To solve most of these problems, you will need a program for working with HDD partitions - you will need to correctly partition and format the volumes so that the OS sees them and installs on them. In some cases (for example, in the case of excessively large volumes on 32-bit systems and Windows XP), nothing can be done, and you will have to put up with the restriction.
How to connect IDE HDD to SATA?

About the same story in the opposite case, with the only difference being that the power problem for the media will be less likely and there will be no speed limits, just keep in mind that an IDE hard drive connected to a modern PC may become bottleneck tasks - even new HDDs with a high spindle speed and the latest version SATA interface are far from sky-high performance - from the same SSD the gain is more than noticeable, therefore, at least, we do not recommend installing it on an outdated your screw operating system. Also keep in mind that IDE devices, unlike SATA, do not support “hot swap” - i.e. they cannot be connected or disconnected while the computer is running - there is a rather high probability of failure of either the device itself or the controller, which is responsible for its functioning!
ISA / PCI / PCIexpress controllers
There are also expansion cards for the PCI connector - if one is on the board, then you can organize the connection of drives using it. On such boards, there may be 2 or more SATA connectors and one IDE - do not forget that it is possible to connect two devices to it simultaneously. The disadvantage of this approach is that by default the OS or its installer it (the PCI controller) with a rather small probability may not be supported, and this will lead to an additional headache with the creation of bootable media with drivers. Plus, the controllers on some chips are poorly compatible with certain systems - either they will not be detected at all, or it will not be possible to select a similar HDD bootable in the BIOS (basically, such PCi boards have their own “mini-Bios” and their own tree of disks), or a computer with him will refuse to turn on at all. Often these problems cannot be solved if updating the motherboard firmware cannot help with them.

There is also one more nuance - the PCI standard had many revisions, while the old ones support a much lower data transfer rate, which may also impose some restrictions. On very ancient personal computers that appeared before the widespread adoption of PCI, the ISA bus is available - there are IDE controllers for it. But due to technical limitations when connecting a more or less normal drive to them, an obsolete bus will become a serious limiter, and with the help of a complex circuit (ISA IDE-> SATA), almost any hard drive can be connected. For modern motherboards without a PCI connector (and there are more and more of them), there is a combined solution for PCIexress / miniPC Aliexpress, where there is immediately both IDE and SATA. With their support, there are far fewer problems, although the speed advantage of the new express standard over the old PCI will not greatly increase the drive's performance (if we are talking about the IDE).

The other day they brought me a problematic PC, suffering from brakes, freezes and other glitches. Its far from young motherboard has only an IDE interface, so the new terabyte SATA-HDD was connected using a specially purchased SATA PCI controller (on a VIA VT6421 chip). The Windows system event log was full of error messages about disk operations, which apparently was the cause of the problems.

Checking the HDD (SMART, surface, file system), replacing the SATA cable did not fix the situation. The computer used to work stably with an old IDE drive, the BIOS was sewn up in the motherboard, and the suspicion fell on the SATA controller. Moreover, in the Windows error log, his name sometimes also "blushed". But experiments with the controller did not bring much success - neither updating the drivers, nor moving it to another PCI slot helped. True, the hard drive seemed to behave better when connected to a different SATA port of the controller, but another "ambush" was waiting for it - when the DVD drive was connected through the second SATA port, the controller for some reason stubbornly refused to boot the system from the HDD. In general, either the controller itself was a little crooked, or it was just that it was “bad friends” with this motherboard or hard drive. By the way, reviews about the controllers on these chips on the internet are not flattering -

I saw a way out in replacing the controller with a similar one, and preferably on a different chip, so as not to encounter the same problems. This is of course, if you do not resort to a radical and troublesome method - replacing the motherboard. In our stores, from inexpensive options, mostly products on the same VT6421 were offered ... And then I saw this kind of thing on sale - at a cost of about 400 rubles, I became interested and decided to try it. As a result, the SATA-shny HDD connected to the IDE-connector through this "tricky piece of iron" was seen by the BIOS, like an IDE-drive, and it worked without any errors. The HDD activity LED on the system unit joyfully began to fulfill its duties, from which it had previously been released by the "good" PCI controller. I left the DVD drive connected, as it was, through the SATA controller on the VIA chip, because there were no problems with reading and burning CDs.

The converter is quite compact, receives energy through the FDD power connector (an adapter is additionally included), has a data transfer indicator, does not require any drivers. In addition, due to its bi-directionality, it also allows you to use the IDE-drive through the SATA-interface. In the case when you need to connect one device and there is no need for RAID-arrays, this is a pretty good economical alternative to PCI-controllers.

Настало время, когда одного жесткого диска в компьютере уже недостаточно. Все больше пользователей решает подключить второй HDD к своему ПК, но далеко не все знают, как сделать это правильно самому, чтобы не допустить ошибок. На самом деле, процедура добавления второго диска несложная и не требует специальных умений. Необязательно даже монтировать винчестер - его можно подключить как внешнее устройство, если есть свободный USB-порт.

Варианты подключения второго жесткого диска максимально просты:

  • Подключение HDD к системному блоку компьютера.
    Подойдет владельцам обычных стационарных ПК, не желающих иметь внешних подключенных устройств.
  • Подключение жесткого диска как внешний накопитель.
    The easiest way to connect the HDD, and the only one possible for the owner of the laptop.

Option 1. Installation in the system unit

HDD type detection

Before connecting, you need to determine the type of interface with which the hard drive works - SATA or IDE. Almost all modern computers are equipped with a SATA interface, respectively, it is best if the hard drive is of the same type. The IDE bus is considered obsolete, and may simply not be on the motherboard. Therefore, there may be some difficulties with connecting such a drive.

The easiest way to recognize the standard is by contacts. This is how they look on SATA drives:

And so the IDE has:

Connecting a second SATA-drive in the system unit

The process of connecting a disk is very easy and takes place in several stages:

Priority boot SATA-drives

The motherboard usually has 4 connectors for connecting SATA-drives. They are designated as SATA0 - first, SATA1 - second, etc. The priority of the hard drive is directly related to the numbering of the connector. If you need to manually set the priority, you will need to go into the BIOS. Depending on the type of BIOS, the interface and management will be different.

In older versions, go to the section Advanced BIOS Features and work with parameters First boot device and Second boot device . In newer BIOS versions, look for the section Boot or Boot sequence and parameter 1st / 2nd Boot Priority .

Mount a second IDE drive

In rare cases, there is a need to install a disk with an outdated IDE interface. In this case, the connection process will be slightly different.

Connecting the second IDE drive to the first SATA drive

When you need to connect an IDE disk to an existing SATA HDD, use the special IDE-SATA adapter.

The connection diagram is as follows:

  1. The jumper on the adapter is set to Master mode.
  2. The IDE plug is connected to the hard drive itself.
  3. The red SATA cable is connected on one side to the adapter, the other on the motherboard.
  4. The power cable is connected on one side to the adapter, and the other to the power supply.

You may need to purchase an adapter with a 4-pin (4 pin) SATA power connector.

OS initialization

In both cases, after connecting, the system may not see the connected drive. This does not mean that you did something wrong, on the contrary, it is normal when the new HDD is not visible in the system. To use it, initialization of the hard disk is required. Read about how to do this in our other article.

Option 2. Connecting an external hard drive

Often, users choose to connect an external HDD. It is much simpler and more convenient if some files stored on the disk are sometimes needed outside the home. And in the situation with laptops, this method will be especially relevant, since a separate slot for the second HDD is not provided there.

An external hard drive is connected via USB in exactly the same way as another device with the same interface (flash drive, mouse, keyboard).

A hard drive designed for installation in the system unit can also be connected via USB. To do this, use either an adapter / adapter, or a special external case for the hard drive. The essence of the work of such devices is similar - the required voltage is supplied to the HDD through the adapter, and the connection to the PC is via USB. For hard drives of different form factors, there are cables, so when buying, you always need to pay attention to the standard that sets the overall dimensions of your HDD.

If you decide to connect the drive by the second method, then follow literally 2 rules: do not neglect the safe removal of the device and do not disconnect the drive while working with the PC to avoid errors.

We talked about ways to connect a second hard drive to a computer or laptop. As you can see, there is nothing complicated in this procedure and it is completely optional to use the services of computer masters.

The production of hard drives does not stand still. Technologies are actively developing: the speed of writing and reading is increasing, the operating life is increasing, new standards and form factors are appearing, which is why many old devices become incompatible with modern computers. Using IDE SATA adapters, you can even make the old machine work with new drives.

Differences between SATA and IDE

IDE (ATA) - a parallel interface for connecting drives or optical drives to the motherboard. Old standard of the 1990s. IDE technology uses a 40 pin connector to connect to the motherboard and separately 4 power pins. Currently, an almost obsolete class. An exception is the old equipment, which is still in operation for unknown reasons.

SATA is a serial communication interface. Now applied to all new devices. It has several advantages over the old system.

The main advantages of SATA:

  • high speed of reading / writing information,
  • increased volume of the drive itself,
  • the ability to connect devices without restarting the system.

There is also a more recent version - eSATA. The same SATA, but guarantees stable contact throughout the entire operating time. It is used for external HDD.

Why do I need an adapter?

There are several problems that can cause a desire to purchase an IDE SATA adapter. For example, an old hard drive with an IDE interface of 80 GB is at home, and you suddenly needed to “pull” a photo out of it. Connecting it to a new computer with SATA connectors does not work.

  1. On the computer, there was a sharp shortage of memory, and an IDE hard drive of the right size was at hand, which at first glance is useless.
  2. The situation may be the opposite: without an upgrade on IDE interfaces, I want to get more additional memory or restore files.

All situations have one solution - use a SATA / IDE or IDE SATA adapter. It is able to convert the data stream from one system to another, thus erasing the boundaries between different standards. The complexity of the application is nothing more than the use of an adapter for microSD cards.

How to choose?

The first step is to decide which adapter is needed. There are as many as five options:

The first two points are suitable for indoor installation. They will be useful if one or more hard drives, or SSDs of different standards, you want to put in the computer case. Usually these adapters do not even have a housing and are not protected in any way. They look like a regular board, where it is intuitively clear where and what to connect.

An important parameter of the adapter from IDE to SATA is the speed of reading and transmitting information. In the case of a USB adapter, it can be 2.0 or 3.0 version. The latter allows you to operate with information faster, but it depends on the version of the computer ports, as well as on the capabilities of the hard drive itself.

IDE SATA with USB output

In addition to adapters for switching between IDE SATA standards, IDE SATA USB adapters can be found on the shelves. This device allows you to connect any hard drives directly to the USB port, regardless of standards. So, you can use the usual as a large flash drive. This is more useful for laptops or tablets.

There are both universal (SATA IDE adapters on one board, connecting several media of the same or different types at once), and separate (only SATA or IDE) adapters. The choice depends on your specific needs and price. An important parameter when choosing will be the presence of a built-in or additional power supply. Without it, the adapter will cost a little cheaper, but will be less functional. There is the possibility of using a central computer power supply, but this is not always convenient, in addition, you will have to unscrew the cover each time.

IDE Series drives are powered by a regular Molex connector with 12v and 5v pins. It is on all power supplies.

SATA drives require a connection for 12v, 5v and 3.3v boards. To do this, you can find the usual 15-pin SATA IDE power adapter with a Molex connector. The problem is that the standard Molex does not have 3.3v wire, which means that it is not able to power a certain block of the board. This feature was taken into account by the manufacturers of disks, to some extent solved.

Connected via a drive powered by a Molex / Sata adapter, it will work adequately on all machines, but not all will be able to support hot-plug technology (removing or attaching to the system during operation). On most modern power supplies there is a separate output - a SATA connector, which is not related to Molex and includes 3.3v power. One way or another, but modern SATA devices do not require 3.3v voltage to work.

Adapter or new drive?

There is no single answer to this question. It all depends on your preferences and budget. At present, the price of memory has fallen dramatically, but it is still not encouraging at some points. Perhaps a more rational solution would be to purchase a new drive or docking station, which will allow you to quickly connect hard drives of different formats on a flash drive basis.

It is worth considering that buying a new hard drive can pull the upgrade of the entire system, while installing the adapter does not oblige you to do anything.

Do it yourself

Most useful electronic devices can be assembled for just a few dollars with your own hands, without any special knowledge of electronics, but the IDE SATA adapter hardly falls into the category of easily reproducible devices. Ultimately, most likely, much more time and money will be spent than in the case of buying a ready-made adapter, although it’s easy to find many working schemes on the Internet. But the "technomonsters" such a task should please.

So let's go

From external signs it is easy to understand that there is nothing similar here. IDE is a wide connector with a flat cable, and “SATA” is a narrow cable. And what to do in this case? I’ll say right away, installing the HDD on a PC with the necessary connectors, copying information to removable media, and then transferring it to your computer is a method for a complete beginner, but we must do the following.

In order to connect the IDE hard drive to the motherboard with SATA connectors, we will use a special adapter - the PCI SATA / IDE controller. It is worth noting that the appearance of various adapters may vary. However, this will not affect performance in any way.

There are such things in the form of separate large boards inserted into a PCI slot that have not only this function, but also a bunch of the rest, like additional usb, etc.:

But I usually buy simple little devices that only have to convert / connect hard drives. Yes, and they are much cheaper.

I like these adapters, as there is the possibility of reverse conversion:

By the way, my favorite site is where I buy useful things for a computer,):

The device is generally a penny, I advise everyone, a good thing. Well done Chinese :)

By purchasing it, we get a double benefit. Namely: both connecting an old hard drive to a modern motherboard, and a modern hard drive to an old motherboard. All you need to do is just connect the adapter to the old drive. Next, bring the Sat wires to the motherboard and that's it, the thing is in the hat, as they say :)

BIOS setup

When all manipulations with the hard drive are completed, you should turn on the computer, and then enter the BIOS. It is important to note that the BIOS is launched on each computer in its own way. To do this, use the key:

After entering the BIOS, you need to proceed to configuration. It is important to assign a boot from the drive on which the operating system is installed. If priority is set incorrectly, the system simply will not boot.

In the event that one of the disks did not appear in the BIOS, it means that the hard drive was incorrectly connected or the cable was damaged. It is recommended to inspect all wires and reconnect (do not forget to turn off the computer).

Once the BIOS setup is completed, you can boot with the operating system. After that, it remains only to assign a drive letter.

Final stage

Since it is not enough to connect the hard drive to the computer, it is necessary to make the final configuration directly from under Windows. On some computers, a similar procedure is carried out automatically. To check this, open "My Computer" and then see if a new disk has appeared.

If nothing happened, you need to start the control panel. Then select "Administration". As soon as a new window opens, you will need to select "Computer Management". In the left column, you need to find the “Disk Management” tab (on some computers, “Disk Manager”).

  • At the bottom of the window, select drive 1 (if more than 2 hard drives are connected, select the drive with the largest number). This will be the new hard drive,
  • You must assign a letter to a logical volume. To do this, right-click on the disk, and then select "Assign Letter",
  • As soon as the drive is assigned a new letter, it must be formatted. The procedure can take a lot of time, it all depends on the volume of the hard drive. When formatting, it is important to choose the NTFS file system.

When the formatting process is complete, a new disk will appear in the My Computer root directory. If for some reason you cannot connect the HDD using the built-in manager, it is recommended to use third-party programs.

An excellent tool for working with hard drives is Partition Manager. In addition, such a utility allows you to split the disk into several logical volumes.


Connecting a hard drive takes no more than 15 minutes. If you follow the instructions, difficulties should not arise. Modern computers do not need additional BIOS setup, of course, if the disks are not installed in a completely new computer. Also do not forget that it depends on the operating system how voluminous a plug-in hard drive can be.

Do not forget about nutrition

Next, you need to fix the HDD in the system unit if you want to use it for a long time. And connect the power cable. A connection diagram will also be provided below. It is worth remembering that there are various power connectors, and if necessary, you need to purchase a molex-SATA adapter.

There are few molex power connectors - you need to use a splitter. It remains only to check how correctly we have done these settings. Turn on the PC (check if the BIOS gives an error). We go to the shortcut Computer on the desktop and check the availability of HDD. Drivers, despite the fact that they are available, are not needed. Since the system itself will install them.

Well, for today, I hope I answered the question about how to connect the ide hard drive to the sata connector. I don’t know any other methods; they most likely do not exist. And in order not to miss a new post, you can subscribe to my updates.
