The computer does not see a hard drive from a laptop

Windows does not see the second hard drive

If after reinstalling Windows 7 or 8.1, and also after they update to Windows 10, your computer does not see the second hard drive or the second logical section on the disk (disk D, conditionally), in this instructions you will find two simple solutions to the problem, as well as the video guide to eliminate it. Also, the described methods should help if you installed a second hard drive or SSD, it is visible in BIOS (UEFI), but not visible in Windows conductor.

If the second hard drive is not shown in BIOS, but this happened after any action inside the computer or just after installing the second hard drive, I recommend that you first check whether everything is connected: how to connect a hard drive to a computer or laptop. And separate instructions on the topic M.2 and SATA SSD in Windows 10. What to do if Windows 10 does not see SSD.

Diagnosis of a hard drive

If the hard drive does not load the operating system or gives a reading error, you must find out its reason:

• If the disk has signs of physical malfunction, or it cannot be connected to a computer BIOS, this means a physical disk failure;
• If the disk is determined in BIOS and has no signs of physical malfunction, most likely, a logical error of reading a hard drive has occurred.

Reference! BIOS is a computer loading system that controls it with internal devices.

If the PC does not load, look in its boot menu. If the menu has a message with the words “Disc Boot Failure”, this indicates a mistake of a system hard disk.

Important! Below is the elimination of system disk errors. Errors of additional discs connected to PC are eliminated in the same way.

Check the disk for noise by bringing the ear to the PC system unit. If an extraneous noise is heard from the block, a clicking or buzzing sound, this is a clear sign of the physical disk malfunction.

When diagnosing the noise of the disk, it is necessary to distinguish them from the noise of the coolers (fans) PC, as well as from the quiet, rhythmic noise of the heads in some models of hard drives.

Reference! PC loading with a “noisy” hard drive can become a serious stress for the disk and finally disable. In this case, it is better to remove the disk by placing it into the external case to copy data.

If the hard drive does not issue extraneous noise, another reason for its malfunction may be the lack of spindle rotation associated with the problem of the disk drive or the banal waste of the power cable.

To check the rotation of the spindle, a “cross” screwdriver is required.

Disconnect the computer from the network.

Unscrew the fasteners of the right side panel behind the PC system unit (view from the connectors) or release the latch in the back of the panel. Perhaps the screws can be unscrewed manually.

Remove the panel, pulling it along the case to the rear of the PC and then moving to the side, removing from the connectors.

The hard drive has a rectangular shape and is placed in a special compartment of the computer. It is usually connected to PC using two cables. Power and data transfer. Gently, but with an effort to squeeze the cables in the connectors of the hard drive, eliminating the possible lack of contact.

Do the same actions on the other side of the cables on the side of the PC motherboard.

Launch PC, and touching the disk from the sides or from above, check whether there is a small vibration on its case that says that the disc spindle rotates.

If the hard drive spindle does not rotate, turn off the PC from the network, connect another supply cable to the disk, and start the PC again to check.

If the disk still does not start, check the documentation of the computer, whether the PC power supply is issued the power necessary for launching.

Reference! If the listed parameters are in order, but the disc spindle does not rotate, you can try to connect the disk into the external case.

The computer does not see a hard drive, old.

In this case, we will consider the moment when the computer does not see the hard drive that has already been installed in the system unit.

Start. Control panel. System and Safety Settings. Administration. Computer Management.

Among the list, find your hard drive and change its letter.

• Another way is to check the disk for the presence of viruses. Use the antivirus program. Some viruses affect the display of a hard drive in a computer.
• The third way to determine the malfunction is to go to the device manager and pay attention to how correctly the connected device is determined (the name of the device should not contain hieroglyphs and signs).
• You can try to reinstall the drivers for USB controller.
• Connect the hard drive to another computer, if the disk is working, then reinstall the Windows operating system.
• Helps in this problem the cleaning of the registry and optimization of the computer. A separate article is devoted to this topic in this blog
• Try connecting the disk through another connector. Maybe the problem is a faulty port of USB.

• And finally, check the integrity of the cords. Perhaps poor contact due to damage.

On a note! If you notice, then at the end of each article I tell you that I published earlier. So be sure to read how to remove tweets in. As well as how to check the video card on the computer. You can also see where to download Bluetooth on a laptop for free.

As you can see, the reasons why the computer does not see a hard drive can be many. Try, I hope you will manage to eliminate this problem. I ask you to ask my questions in the Комментарии и мнения владельцев, and I will be happy to answer them. I wish you all the world!

By the way, I had a tablet on Windows, I took it just from a friend, not mine, I connected well. And then I wondered, and if Linux is standing on the tablet, whether it will see a linx, because Linux and Windows on different cores, plus the file system is different. Water is such a question, who knows, tell me) I will be grateful)

Does not see the computer, but does not see Windows, this is, and this is, as they say, two big differences. Когда комп не видит диск, то его нет ни в загрузке, ни в управлении дисками.

Greetings, Alexander! I try to call articles as people understand this. After all, they set these requests in search engines)

The computer does not see a new hard drive. It was my request to the search engine) thanks to the author. I’m just not a “thousand programmer” and the article helped me.

Thank you for the article, helps.I forget where to look for after the reinstall)), usually everything is in place.

Thanks. Very helped out. The computer did not recognize the disc due to the fact that the letter was not assigned to him! Thanks.

Good evening, Egypt! The article, of course, is useful, but it is not suitable for my problem. Such a thing, an external drive (Western Digital My Book World Edition 1TB) over the past couple of weeks of life, has disappeared and appeared at times and appeared. Once he generally stopped appearing, both in the “Disks Management” and in the BIOS. Controller (PCB Board) was covered, sure. The restoration of the system did not help. I connected it directly (instead of a drive) and it appeared in the BIOS, the system automatically installed the desired driver and it also appeared in the “Disks Management”. And in the conductor it is not there and in the playlist in WMP only those MP3 files that are in it are not lost. For several days I have been looking for and reading different forums and articles, I have not found a solution to such a problem. It does not work to change the letter, this option is not displayed with the right click on the disk, unlike the main disk from. What to do? Windows 7, ASUS P6T, Intel i7 920, GeForce GTX285, Antec EA-500 PS PS: In it I have the necessary information.

Either the hard drive is slowly dying, or the box in which the hard drive sits is inoperative. Try to check the performance of the hard one by connecting it to another computer.

It is not clear why you wrote it. I already wrote that the controller was covered and if I connected it directly to the computer, then the disk is no longer in boxing. There is no second computer, they stood out of the basement.

The computer does not see the external hard drive connected via USB

And what to do if the computer does not see a hard drive connected via USB? Almost everything is the same as mentioned above. The only difference is that in BIOS we check whether USB controls are included. In Award BIOS it is USB EHCI Controller, USB EHCI Controller, USB Keyboard Support, USB Mouse Support and Legacy USB Storage Detect, AMI Settings of Advanced. USB Configu.

The external hard drive may also not be visible due to problems with USB ports. Their serviceability also needs to be checked.

Lack of power is another reason why the external drive may not be recognized by the system. Do not use extension cords if possible, the connection itself must be made through the port on the back panel. If there is such an opportunity, use an autonomous power source when connecting discs, this will increase the stability of the drive. And the last. The external disk may not be recognized by Windows for the same reasons why the system does not see flash drives and other equipment connected by USB devices. With the article “The computer does not see a flash drive”, perhaps you will find a lot of useful things for yourself.

Why does the computer not see the disc when installing Windows

The problem is typical for laptops and ultrabooks with caching SSD, as well as for some other configurations with Sata/Raid or Intel RST. By default, there are no drivers in the installation program in order to work with a similar data storage system. Thus, in order to install Windows 7, 10 or 8 on a laptop or ultrabook, you will need these drivers at the installation stage.

Update 2017: Search for the required driver start from the official website of the manufacturer of your laptop for your model. The driver usually has the words SATA, RAID, Intel RST, sometimes. Inf in the name and a small size compared to other drivers.

Most modern laptops and ultrasounds on which this problem arises is used by Intel Rapid Storage Technology (Intel RST), respectively, the driver should be sought there. I give a hint: if you enter a search phrase of the Intel Rapid (Intel RST) storage technology, you will immediately find and can download what you need for your operating system (for Windows 7, 8 and Windows 10, X64 and X86). Or use the link to the Intel http: // Downloadcenter website.Intel.COM/Product_Filter.ASPX?Productid = 2101lang = Rus in order to download the driver.

If you have an AMD processor A, respectively, the chipset is not from Intel, then try the search for the key “Sata/Raid Driver” “Mark of the computer, laptop or motherboard”.

After loading the archive with the required driver, unpack it and place it on the USB flash drive with which you install Windows (creating a bootable flash drive). If the installation is made from the disk, then still place these drivers on the USB flash drive, which should be connected to the computer before it is turned on (otherwise, it may not decide when installing Windows).

Then, in the Windows 7 installation window, where you need to select a hard drive for installation and where no disk is displayed, click the “Download” link.

Indicate the path to Intel Sata/Raid (Rapid Storage). After installing the driver, you will see all sections and you can install Windows as usual.

Note: if you never installed Windows on a laptop or ultrabook, and by installing the driver on a hard drive (SATA/RAID), you saw that there are 3 or more sections, do not touch any HDD sections except the main (the largest). Do not delete and do not delete and do not format, they stored official data and the recovery section that allows you to return the laptop to factory settings when it will be required.

Mechanical damage to contacts, wires or ports

It is not necessarily that the problem has a systemic nature. Quite often, the malfunction consists in the breakdown of one or another component of the hard disk. Check it is quite simple, just find another cable and change it. If at the same time the hard drive began to work, then you found the root of the problem. Similarly, the procedure is done in the case of other similar malfunctions. Try using another connector for connection or change wires. Often the culprit of the breakdown is an inexperienced user who simply incorrectly or did not completely connect the hard drive to the computer.

Initialize the disk (format it, if new)

In some cases, Windows does not initialize an automatically connected new disk. Of course, this can be done manually.

First you need to open a special. Disc control utility (built into Windows): Just click Winr. And then use the DiskMGMT command.MSC.

Diskmgmt.MSC. Run disks control

All connected drives connected to the computer (not formatted and not initialized discs should be displayed in the management of the disks. Including).

As a rule, a “red” circle will burn over the non.Initialized disk. Just click on this disk with the right mouse button and select the initialization function.

After indicate the table of sections (you can leave by default, which will recommend Windows) and click OK.

Further, called the disk, a new status will appear. “Online”. Cm. Screen below.

After that, note that the new discs in the vast majority of cases go not formatted (in the management of disks. Opposite them there will be a black strip with a non.Distributed area). For formatting HDD. Just click on this area with the right mouse button and select the option of creating a simple volume.

Next, you need to specify the size of the volume. In most cases, you can leave the default value and press “further”.

After the disc is set (you can specify any free).

Well, the penultimate step. Indicate the file system. If you have a portable disk (USB). I recommend selecting the Exfat file system, otherwise. NTFS.

IMPORTANT ! When formatting the drive. All the information on it will be deleted! If your disk is new, then, as a rule, there is nothing on it, in addition to the factory utility to create a quick backup.

If everything went successfully, after formatting you should see the status of the disc “service”.

Opening “my computer”. The disk should be displayed, like the rest. Now you can work fully with it!

The computer does not see the external hard drive

Difficulties with recognizing and opening external disc drivers are most often due to the following:

• USB nests do not give out sufficient voltage to power disk. To exclude this version, connect the disc to the rear USB ports located on the motherboard.
• The drive is connected to the USB version 3, with which it is incompatible. To check, connect it to USB 2.0.
• A cable or adapter connecting the disk with a computer has a defect or a large resistance (extinguishes signals through the data line).
• The disk itself is faulty.

If the PC does not see the device in a removable case (case), if possible remove it and connect it directly via SATA port. The reason for the inoperability can lie in the USB-Sata adapter built into the case.

External discs with the USB integration are often refused due to breakdown of the connector. In some cases, such devices can be converted under the SATA intensity. It is unaesthetic and not too reliable, but allows you to save information. If the disk modification does not support such an alteration, then it can only be restored by replacing the controller board.
