Connect a new hard drive in windows 10. The computer does not see the hard drive - what is the reason? External hard drive and user data

You have multiple disks on your computer, a reinstallation or upgrade of your Windows systems 10, and suddenly it turns out that the computer does not see the second HDD hdd / ssd or the partition disappeared.

See what to do in this case and where to look for the cause of the problem. Often this also happens when a new hdd / ssd is installed or after formatting an old one.

The situation may seem strange because the disk is probably visible in the BIOS. The solution to this problem is trivial.

It just isn't formatted or has no partitions created on it. To fix this situation, simply go to the appropriate options in Windows 10. To do this, open the classic control panel and select "System and Security."

Then we look down and find the "Administration" section - open it.

The next step is to go to the "Computer Management" category - double-click.

Now we go to "Disk Management" - click on the line once.

If you see a black strip, then this is a section that the system does not see - it sees only blue. Right-click on it and select the line "New simple volume".

Now we need to create a section. For this purpose, we determine the amount of space that will be allocated to him. The system will ask for a drive letter, and finally format the media.

The recommended file system is NTFS. Optionally, you can specify a label, which is the name and will be displayed in the file explorer. At the end, click "Finish" and from this moment the drive should be visible in the Windows 10 system.

If the above method did not bring the expected results, it is worth checking if the media is connected to the computer correctly - check that two connectors are connected to the connector: SATA and a power supply.

windows 10 does not see the hard drive - make sure the cables are connected correctly

It often happens that, as a result of a system update or a complete reinstallation, other hard drives connected to the computer are no longer visible.

In theory the hdd or ssd is properly connected to the computer, but after opening the This PC window, it does not appear in the list of connected devices.

Where can you find the reason? If you have desktop computer make sure the SATA cable or power supply is not disconnected from hard disk accidentally.

Remove the side cover and check the cables connecting the drives to the motherboard.

Windows 10 computer does not see the second hard drive - Check Device Manager

The next step is to check if the hard drives are visible at all as connected to the computer.

This can be done using the device manager - if they are connected but disconnected at the same time - then they can be reactivated.

To do this, go to "Device Manager". Then we expand the "Disk drives" tab.

You will be shown your hard drives connected to your computer. If detected and enabled, they will be displayed simply with an icon, without any additional markup.

If they are connected, but for some reason disconnected, a red icon with a down arrow may appear next to them - in this case, you must right-click and select “Enable”.

Finally, there may be a third scenario - undetected disks will also not be displayed here if, for example, they are missing.

In this case, it means that it is not even detected as connected to the computer - the reason may be damage (or poor contact) of one of the cables (SATA or power supply) or even a physical failure.

Windows 10 can't see hard drive - check assigned letter

This is the most common problem and the easiest to fix. Partitions may have been unmounted during a system upgrade or reinstallation, so they do not appear in My Computer.

To check this and assign a drive letter, enter the Windows 10 Disk Management window. To do this, press the combination Windows keys+ R and enter the following command in the new run window:

A new control window will appear. Below we see the division of disks and partitions. Each partition is added with its name (if you specified one) as well as the drive letter. It may just turn out that some sections do not have a letter.

How to assign it? All you need to do is right-click on it and select "Change letter".

In the new window, click "Add" and in the "Assign the next letter" field - select one of the presented ones. Finally, click OK to close the windows.

Your drive will receive the selected letter and will be immediately visible in the "My Computer" window.

Making the second disk visible using the command line (it's better for beginners not to try)

If the methods above did not help you, and a basic disk without extended partitions (for dynamic and RAID this does not work) windows system 10 can't see run command line from administrator and enter the commands:

diskpart
list disk

Remember the disk number, which is not visible to the computer and enter the command select disk F (F is the disk number) and press Enter.

All your data will be deleted, so think carefully especially if there is something important.

If the second is not visible physical disk, use the following commands

clean
create partition primary (you can set the parameter size = S, for the size in MB, if you need several).
format fs = ntfs quick
assign letter = F

If there is an unallocated area, all the same commands are used, but without clean. Only use this option if you know what you are doing.

If you are unsure, in some doubt, save your data or refuse such a step altogether. Good luck.

In this short tutorial, we'll take a look at how you can partition your hard drive into Windows environment 10. It differs from similar materials in that we use a snap-in called "Disk Management" to solve this problem. Although the built-in tool does not have a significant part of the functions that are inherent in utilities from Acronis or the free AOMEI, it is easy to learn, operate and completely safe.

Application launch

To run a program in Windows 10 that allows you to partition your hard drive, we will use the Control Panel.

We go to the "Control Panel" using a shortcut, WinX menu or search bar.

We launch its applet called "System and Security" while rendering the elements in the form of categories. When displaying items as icons, proceed to the next step.

In the "Administration" section, click on the link "Create and format hard disk volumes".

The "Computer Management" window will appear before the user's eyes, allowing you to divide the hard disk into logical partitions.

Shrink the section to create a new one

In Windows 10, like previous editions of the windowed OS, you can partition the disk into several using the free space on the original volume / media.

Explanation: if you want to make several from one section, make sure that free space on it, at least a few percent (or better by 10% due to incredible defragmentation) more than is required to create a partition.

To create new disc, it is necessary to "bite off" some of the free space from the existing volume.

We call context menu section, which we plan to split in Windows 10, and select the command "Shrink volume ..." from the drop-down menu.

We are waiting for the polling and verification of the hard drive.

The procedure can take up to several minutes on damaged and bulky media, and if there are a fair amount of bad sectors on the surface of the magnetic platters of the drive, you will have to check it and then fix the damaged areas.

At the end of the procedure, a window will appear where you must enter the size of the compressible space.

The specified volume will be used to create the new partition (s). The size of the original disk, which it will become after compression, is shown in the last column.

After a few seconds, the "Disk Management" utility window will be updated, as a result of which the partition table will change slightly visually: the hard drive will acquire a new area called "Undefined."

Create a new section

The disk is compressed, and an unallocated one is allocated to form a new partition, that is unused windows 10 area.

To turn the unallocated space into a full-fledged partition, you need to call its context menu and select "Create simple volume".

In the first window of the wizard for creating simple sections, click "Next".
In the second window, set the desired size of the new volume (by default, the maximum value will be entered), if you need to create several partitions. Otherwise, do not touch anything.

Select a free letter label from the drop-down list and click on the "Next" button.

In the formatting window, set the desired parameters and click "Next".

Choose NTFS as your file system due to support for files larger than 4 GB.

In a few seconds, Windows 10 will prepare the hard drive with the new partitioning scheme for use. Now the new volume can be used to store personal data, install another operating system(for example, any of the Linux distributions) or Windows installations from the hard drive, which eliminates the need to create a bootable USB flash drive.

Greetings, dear readers.

Some computer users are faced with the problem when the drive does not see Windows disks 10. If you see similar "symptoms" on your device, do not immediately run to the store for a new reading component. Such an ailment can appear as a result of various reasons. There are many ways to bring an element back to life. In the article below, I'll show you how to do this.

The first thing to start with is to determine the nature of the disease. Check if the problem only appears when reading some or all of the disks. So, if it performs its functions selectively, the drive is most likely faulty. If the situation repeats with everyone - a software failure.

How to fix it at the software level?( )

What to do when your discs suddenly stopped reading? Remember what exactly has been installed on the equipment lately. It could be games or programs. Often, virtual managers such as Alcohol 120, Daemon Tools and the like are a problem. In addition, such "symptoms" appear as a result of being placed on a laptop or desktop computer programs for data recording - Nero.

To solve the problem, you just need to uninstall the previously installed software. If that doesn't work, use the System Restore tool. I have already talked about this more than once before.

If the ailment disappears, we try to install other versions of solutions that will not interfere with the operation of the drive. And in general, it is better to remove all unused software from the device. This has many positive aspects.

Driver( )

In addition, sometimes problems appear as a result of driver failure. The solution is as follows:

If the DVD drive continues to refuse to perform its functions, we make additional movements:

If this does not help, we take a few more steps:

Opening the tree “ IDE ATA ...". We are looking for the controller to which the floppy drive is connected. To do this, open each channel in turn and check " A type».

We find the option " Enable DMA”And mark it. If she was there, we shoot. We restart, and then we return it back.

Hardware failure( )

Why the drive might not work at the hardware level? There are many options. The first thing to do is change the connection cable and power plug.
Alternatively, you can use a dedicated cleaning disc. It has micro brushes that will clean the laser head. But before that, make sure they are flexible.

Well, the worst option is, of course, the complete failure of the component we need. The solution is to buy a new one.

This article is intended to solve the problem when Windows 10 does not see the hard drive or part of it. That is how to work with sections.

We go to "My Computer". For example, in our example, a 2TB hard drive is connected on the computer, but in the list of partitions only one 300GB is visible.

If the second hard drive is connected, then it is also not visible. This means that either it is not connected, either it is not there, or simply no partitions have been created.

Let's start solving the problem. Click on the right mouse button on the start icon and go to the "Disk Management" section.

A window will open in which we will see that 500 MB are reserved by Windows, 300 GB, as we have already seen, are allocated to the "C:" section, and 1562.5 GB are not defined.

Click on the right mouse button on the unallocated volume and click on the "Create simple volume ..." item.

The "New Simple Volume Wizard" starts. Click on the "Next" button. In the next window, you can specify the size of the partition to be created.

You can leave the entire free space, or you can specify a smaller size if you want to create more partitions. Click "Next".

At the next step, you need to choose which letter to assign to the section. Next, it is proposed to choose file system... It is desirable to keep NTFS. We put a tick on "Quick formatting".

The next window shows all the data about the partition, where all your previous settings are listed. Click on "Finish".

In just a few seconds, a new section appears in the system.

There is an option that the section will appear, but it will not be available for work. To fix this, you can right-click on it and select "Format".

To create several disks, you need to repeat the procedure for creating a partition, only indicate not the entire available volume, but only a part (for example, 500 GB out of 1500 GB).

Then repeat the procedure again, including the remaining amount of free memory in the next section (the remaining 1000 out of 1500).

Be sure to check the box "Quick formatting" otherwise it will start formatting as usual, which will take a lot of time.

You also need to know that you cannot share discs with information, because it will be deleted.

As a result, we get 3 sections.

To delete a partition, enter the familiar "Disk Management" and, by clicking on the right mouse button on the partition that you want to delete, click on "Delete volume ..." or "Delete partition", whichever you want to delete.

Thus, we can work with disks if we do not need information on them. That is, before splitting a volume, you need to format it.

And such sections as the section with the system cannot be formatted.

Now let's take a look at what actions can be performed with hard drives in Windows 10.

Right-click on the section and select "Properties".

In the "General" tab, we can rename our section, allow files to be compressed or indexed.

For the changes to take effect, you need to click the "Apply" button.

On the "Service" tab, you can check the disk or optimize and defragment disks.

To disable scheduled optimization, click on "Optimization".

In the window that opens, go to "Change parameters".

Uncheck the "Scheduled optimization" box.

You can leave this feature enabled, but it may freeze the system during optimization.

The "Hardware" tab displays what disks are on the computer (DVD-ROM, hard drive).

V " General access»You can enable access to files and folders for other users if the computer is connected to a local network.

In the "Settings" tab, you can define the format of files on the disk, change the image of the disk display.

There are also tabs "Quota" for sharing hard disk between different users, " Previous Versions"And" Security ", where you can set access rights for different users.

In general, all the settings are not very different from Windows 7.

What to do when the computer (PC) on Windows 10 does not see the hard drive

The other day I bought new hard drive and was somehow suddenly surprised that it was not identified, or rather did not even show it, my computer. The solution turned out to be the simplest and was right under my nose.

The fact is that this is a feature of the operating system (OS) Windows 10. Even if hard drive visible in BIOS(BIOS), the computer will still not recognize it and will not show it until you allocate its volume or create a new partition. This can be done in the following way.

Disk Management on Windows 10

To turn on " Disk management"on Windows 10, right-click on" Start"in the lower left corner.

A program window will open in front of you, where all your internal drives and hard drives are listed ( HDD). We are interested in a disk on which the volume is not distributed across volumes.

To open the window " Simple Volume Wizard", click on the area of unallocated disk space ( shaded area) right-click and select " Create simple volume".
