How to change the hard disk on the computer. Turning off and removing drives on PC

We learn how to remove a hard drive from a computer: Step-by-step instructions

Buying a new HDD or the replacement of the old faces users to the question of how to remove a hard drive from the computer yourself. It will have to remove it with marginal caution so that it can be used in the future and do not apply physical damage mechanical parts. The slightest blow can lead to full hard disk dysfunction.

It often happens that with one computer you need to transfer data to another, but removable drives do not have the amount of memory and data rate and data rate. In this case, you have to rearrange the hard drive in another computer. If you follow the instructions, the removal of the hard disk from the computer can turn into a conventional routine.

Replacing the hard disk

Replacing the hard disk (HDD). another step of hardware repair or upgrade, which is not only necessary for increasing free memory, but also performance. Replacing the hard disk is necessary if the read speed from the drive has become too slow, or it simply refuses to work. The main parameters of this device. spindle rotation speed, cache. Nowadays, the most popular intees for connecting hard drives. SATA and SATA II.

For personal PC designed SSD drives

SSD drives consist of a memory chip on the type of flash card, unlike the usual, in which the physically itself is a set of disks, reading head, which rotates them. Actually because of this difference SSD drives work much faster, quieter, and do not heated so much. It also works faster than flash drives due to the fact that it is not connected to USB, but directly to the time for the HDD inside the computer. The lack of it is that it is much more expensive and less in terms of volume. The speed of reading information from these carriers is a priority parameter that should not be ignored. No matter how much the RAM is used on the computer, the performance of SSD or conventional HDD will be strictly fixed. If the data is read not enough, it means that the hard disk failed or clogged by unnecessary information.

HDD replacement is one of the discharges of computer aid, the release of new video cards, processors, the motherboard requires improvements and for HDD, which is why it is necessary to periodically produce its hardware stuff.

Below you can see how to install hard drive.

How to connect hard drive to the motherboard you can look at the video below.

Attention! On the video above only the connection of the hard drive to the system board is considered! It is also necessary to connect power from the power supply. Find out how to do it you can here.

How to make an energetic rude disk

When buying a new hard disk, either the methamoz of the dilapidated occasions is required to perform operations allowing it to become its sections energetic. In the displeasement, you risk losing access to the operating system.


First try to make a hard disk section energetic, applying the probabilities of the operating system. This method was tested on Windows XP and Vista operating systems, but it also applies to Windows SEVEN system. Open the Start menu and select “Follow”.

Enter the COMPMGMT command in the field that appears.MSC. Click “OK”. Discover in the “Computer Management” menu subparagraph “Storage devices” and go to it. Select “Disk Management” item.

Highlight the hard disk section (or each disk), the one that needs to be done energetic. In the right column of this window, select “Make a section energetic”. In the case of Windows 7, this item will be posted in the “All Tasks” menu. Click “OK”.

In the event that you cannot access the operating system, use the command line to correct the energetic section. Run the Windows Vista (Seven) installation disk or LiveCD for Windows XP. Turn on the command line support and run it.

Enter the DiskPart command and press Enter. Now enter the List Disk command, later then press ENTER. The working window will appear a list of hard drives that will be numbered. Choose the section that you need to make energetic.

Select the desired section by entering the SELECT PARTITION command 1 or 2. In order to make this section energetic, enter the Active command. If you did everything right, then later pressing the Enter key should have the following message: “Section is marked as energetic”. Restart the computer to check the operability of the OS.

How to choose HDD and SSHD


Intees connecting new and old drives ideally should be the same. Almost all laptops released in the last ten, support SATA inteeis drives. The exceptions make up some ultrabooks and netbooks with integrated flash memory. both on smartphones and tablets, or with support for only thin SSD standards MSATA and M.2, but we will not talk about them now.

If your old disk has the same, the problem of replacing problems will not.

On the ancient machines released before the appearance of SATA, the discs are connected to a wide loop by Ide’s intees (PATA):

It is almost impossible to find the new hard drive of this format today, therefore, most likely you will have to connect the SATA disk through the adapter adapter instead. For example, this type:

But note that such a replacement is relevant only in the event of a breakdown of native hard. New, whatever it is none, will pass and receive data at the same speed as old.

Generation SATA

Generation of SATA intees (1, 2, 3) characterizes the bandwidth or theoretically achievable data exchange rate between the drive and the motherboard. Modern generation SATA. the third, supports transmission at 6 Gbit / S. Previous. Second. 3 Gbit / S, and first. 1.5 Gbit / s. Boards and discs of different generations are compatible, but the exchange between them will occur at the speed of a slower device. For example, if the laptop platform belongs to the SATA-2 generation, and the Winchester is to SATA-3, the data will be transmitted no faster than 3 Gbit / s. However, even if the computer is old, buying sata-1 and 2 hard hard. After all, it is possible that you will once want to rearrange the disk to another car, and it will be its weak place.

Form factor and thickness (height)

From the dimensions of the hard disk depends, whether it will fit inside the computer. Standard Winchesters for laptops are available in two form factors. 2.5 “(ordinary) and 1.8” (small. for netbooks and ultrabooks). 2.5-inch discs can have a height of 9.5 mm, 7 mm and 5 mm. The latter are rare.

On the replacement of the old one is suitable disk of a similar form factor and the same or less thickness. But in the latter case we will have to put seals under it, otherwise it will hang out.


Capacity (capacity) of a new hard can be any, the main thing is to have it enough. However, for laptops of the older generation. based on the BIOS (T. E. Without the support of UEFI) there is no point in buying disks with a capacity of 2 TB, since everything that over, the system will not see. It’s interesting: CPU Package: What it is and what temperature it should show

High-speed disk characteristics: spindle rotation, buffer volume, IOPS

Standard mobile hard drives rotate at a speed of 5400 or 7200 RPM (revolutions per minute). The higher the turnover, the faster access to the data, however, high-speed discs are stronger and louder noisy. In addition, large heat products with a lack of cooling in a close laptop housing can lead to a sudden horse of hard, so devices at 7200 RPM are less reliable. Memory buffer capacitances, where temporarily stored information read from the plates, too much does not happen. The bigger, the better. Hybrid Hard. SSHD, as already said, there is another buffer. Flash, like SSD. When choosing its volume (more) and type: Optimally. MLC, as durable, fast and inexpensive.

IOPS. This indicator determines the speed of the random (random) read and write to the 4-8 Kb blocks. the main type of disk operation with the usual use of the computer. This is the most informative performance of the drive, but, unfortunately, it is not always indicated in the characteristics. Than he is higher, the better.


That’s what you should not do, so it is to choose the brand hard drive. I advise not to take it into account at all, since today all the manufacturers of hards took the course not on quality, but on the bumping of the market with their products. It is more profitable for them to return money for defective devices after sale than to rebel them in production. Objectively, no brand of HDD cannot be considered more reliable than others. Approval of the opposite. just someone’s personal opinion.

Unfortunately, none of the solvent parameters allows you to predict how much it will last, so be sure to see its warranty. Those whose guarantee is less than 3 years old, not worth buying.

What is the role of a hard disk and where it is

Winchester is located inside the system unit, between two actuators of different types. Sometimes the RAM strips are located above it.

Hard disk is designed to record and storing long-term information. Very often, inexperienced users confuse “Hard” with RAM. and this is rooted incorrectly. The fact is that the RAM does not store information in itself, and processes and transmits it to the processor or other parts of the system. Hard disk, in turn, can store all the information and record it infinite.

Step Three: Install a new disk

Installation actions (or replacement) disk are slightly different, depending on whether you are installed on a laptop or desktop PC.

Installing your new disk in a laptop

Different laptops have different ways to access the drive, if they allow easy access. In some business class designs, you can replace the disc, twisting one screw, it may be necessary to be required to fully remove the bottom of the machine or even took out the keyboard. Usually you can find specific instructions by following the search on the manufacturer and the model of your laptop.

In this example, we replace the disk in the ThinkPad T450s. The project has been for several years now, but it is so small that it requires the removal of the entire bottom, which is quite typical for designs that allow you to upgrade the hard disk.

To access the disk, I have to remove the battery, and then remove eight different screws.

It loosens the metal plate of the body enough so that I can remove it from the computer. You can see the hard disk in the lower left corner.

To pull the disk itself, I need to unscrew another screw, pull the disk slightly, and then remove it from the built-in SATA connector.

For this model, the drive disk is simply a thin piece of aluminum with a rubber bumper. I took it off, and then placed it on a new disk.

Then I completely change the process, inserting a new disk into the SATA connector of the laptop, screwing the housing back to the frame and replacing the housing panel.

Again, this process will vary greatly depending on which laptop you have. If you need a step-by-step breakdown for your model, Google. your friend. you usually find at least several users who want to do the same, and possibly an article or video if you are lucky.

Installing your new disc desktop PC

This process is a bit more difficult than on a laptop, but good news is that to remove the case and access the disk is usually much easier than most laptops.

You will need a standard screwdriver with Philips head and SATA cable. If you fully replace one disk, you can use the already connected SATA cable. Your power source probably has a free SATA connection. several connectors are often available. but if not, you will need a transition cable. If you work in the area, which is especially exposed to static electricity, you will also need an antistatic bracelet. If you built your own computer, the screws needed to install a new disk should have been shipped with a case. I hope you have saved the box with accessories. If not, you need to get a few screws to replace. Finally, you will need a bowl or a cup for screws.

Turn off the machine and disconnect all cables, then transfer it to the workplace. It should be a cool, dry place to which it is easy to get, preferably without carpet under you. If you know the configuration of the internal parts of your computer, do not hesitate to place it at the most affordable angle. If you do not do this, just leave it in a vertical position. you may need to remove several panels for full installation.

Remove the access panel from the main side of the housing. it is left if you look at the computer in front. Most designs require you to remove two or three screws from the back side before it slides or turns out. Postpone the access panel to the side. Some desktop computers require that you remove the entire case cover, and not just the access panel. If you are not sure, look at the table of the desktop or the internet case. Instructions should be easy to find.

Find a minute to navigate. If you work on the usual desktop computer, you probably look at the motherboard with a square power supply at the top or bottom of the case. You must see the drive or disks of your computer installed in the front of the case. SATA data cable must be laid from the motherboard to the disk. SATA power cable must be laid from the power supply to the drive.

Note. If you do not see any 3.5-inch disc of larger size, no 2.5-inch drive of smaller size, it can be accommodated elsewhere. In newer projects, it is often behind the motherboard. delete the opposite access panel to check.

If you do not leave your old disk in your system for additional storage, it’s time to remove it. You can also leave cables connected to the motherboard and power supply, and then simply connect them to a new disk after installation.

First, disconnect data cables and power from the back of the old disk. There is nothing too complicated in this: just pull it out. Some cables are equipped with a small tongue blocking mechanism that you need to compress first.

If the drive is located on the retractable box, remove it (and note that some pull-out boxes are screwed into place). Now just use your screwdriver to remove the screws from the drive, regardless of whether it is in the case or attached directly to the body. Screws come in different sizes and lengths. some of them include silicone gaskets for sound damping. and can be installed on the bottom of the disk or on the side, depending on the design of your case. In fact, it does not matter: just remove them, put them in place where you do not lose them.

How to Install / Replace Hard Drive in Computer (System Block)

Installing an additional hard disk in the system unit differs from its replacement to a new one that in the first case you need to determine the free space for installing the second drive. You also need to have another free set of cables for connecting additional HDD to the motherboard and to the power.

At the same time, we mean that hard drives are 2 main types of inteeis connectivity: PATA (IDE) and SATA.

So, if we want to replace the old hard drive for a new one, in this case it is easier to purchase it with an inteeis of a connection similar to the old disk. True, the IDE standard is already obsolete, but nevertheless, HDD is still encountered. If you need to install an additional hard disk or instead of the old, but with another connection inteeis, in this case do not forget to take care of the availability of appropriate cables.

We also consider that if we have a SATA connection drive, then you need to double-check which intee of the Maternal map of our computer, as SATA happens different options: SATA, SATA 2, SATA 3.

On the motherboard, the PATA and SATA and SATA cable connectivity is indicated.

We change the HDD in the computer or install an additional

Turn off the computer from the power supply and remove the side panels in the system unit.

If we change the old hard disk to a new one, we simply disconnect the power cable and the data cable, and also unscrew the bolts that attached HDD. Take out the former HDD and install a new, fixing and connecting in reverse order.

If we install the IDE hard disk, then you need to put a jumper (jumper) at the same position as the old. This jumper is located on the rear end of the disk: there, where and connect all cables. Also, the scheme of the correct jumper installation is shown on the disk (from above).

This jumper in hard drives with an IDE-inteeis connection is designed to exhibit in which mode this drive will work: it will be leading (master) or slave (Slave).

If we set an additional hard disk, you connect it to power, as well as the free port of data transfer on the motherboard using additional cables. Also for fixing the second hard disk you will need 4 additional bolts.

For better cooling HDD, it is desirable to place them not exactly to each other so that there is a free space for ventilation. If there is no such possibility, we recommend installing an additional fan.

We collect the system unit, turn on and configure

After installing the HDD, the side walls of the system unit and turn on the computer. Further actions depend on the goal for which a new or additional hard disk was installed. Options may be different:

  • The new HDD was installed to replace the old and you need to transfer all the information, including the operating system;
  • To the new hard disk you need to install a new operating system, such as Windows 10;
  • Additional HDD will be used only as a separate storage drive for storing files that do not relate to the operating system (video, audio, photo, documents, etc.P.).

This article does not imply consideration of further actions, so we will discuss them in other topics. Register in our project to receive news, including new articles!

Windows 8/10

The preparation of the carrier in these systems is practically no different from the already familiar process with the 7th. Difference in small trifles. On them and pointed attention.

Hard disk initialization

Go to the initialization menu by following.

  • Click PCM on the Start panel.
  • Go to “Disk Management”.
  • Click on a new disk, if necessary, divide it into several local.
  • Select a suitable disk markup.
  • Repeat the same procedure as with Win7.

Note: How to make GIF Animation in 5 minutes: online services, photoshop, applications for phones

Creating a new volume

Disk formatting is the same algorithm that in Windows 7:

  • Go to “Disk Management”.
  • Find a new disk (marked “not distributed”) and click on it PKM.
  • In the drop-down menu, select “Create a simple volume”.
  • The “Master” opens, select the letter for the local disk and format it in NTFS.
  • Tap “Quick Formatting”.

We solve and decide!

If the computer requires formatting an external hard disk on which important data is stored, then you should not panic immediately! In 90% of cases, the disk check for errors saves PC from loss information. We will analyze the process itself below. It is important that if you are unsure in your actions, you should contact the specialists!

We will use the standard Windows command. CMD. Run on behalf of the administrator, enter the following code on the command line (without quotes): “CHKDSK D: / F”. For example, the code is shown for the hard drive D, replace it with an external carrier letter, requiring check. After the actions, click Enter. Further, the work will be produced automatically and, once requiring formatting a removable hard disk, will start with all the important data for the user.

Did not help? Do not despair!

In the second way, third-party reconstruction programs are used. Download and run R-Studio program. At the initial stage of a couple of action: 1. Choose hard drive 2. Press “Scan”

After the scan is completed, find and open and open the “EXTRA FOUND FILES”! On the left we choose full or partial recovery, putting a tick. Then press the Recover button and specify the path to restore.

The second utility capable of solving the problem is called Recuva. The actual numbers from the real example: a person on the external rigid DD was 600 GB of information, the program restored the main 200 GB (tens of thousands of photographs, songs, hundreds of films and over a dozen archives). The process is very long, for this reason the person did not recover the remaining data. From this it follows that 400 GB turned out to be “garbage files”. So, to speed up the process, make sure that you do not restore unnecessary information! Below on points is the procedure for action. So how to restore a removable hard disk without formatting? one. Run the Recuva 2 program. Select the data type for recovery, if such several are “all files” 3. We celebrate the device on which they are. 4. Click “Start”, after which the utility will start searching. 5. Choose the way and wait!

Pay attention to the color of the icon opposite the found file after checking, before restoring. Red marks were noted damaged sections or data, but even there are a chance to restore fully, so you should not shoot a tick!

Decent mention

The principle of operations of programs is the same, therefore, for the third time, to paint all the actions on the steps does not make sense. Good work with files Shows the ICARE Data Recovery Software utility, which includes 4 programs: Partition Recovery. for remote sections of the hard disk. Deep Scan Recovery. Scanning and File Search, Format Recovery. Restore Files with Media Information Deleted File Recovery. To restore remote files.
