Если вас не устраивает буква, назначенная для диска, или у вас есть диск, который еще не получил букву диска, можно использовать управление дисками для ее изменения. If you don’t like the drive letter assigned to a drive, or if you’ve got a drive that doesn’t yet have a drive letter, you can use Disk Management to change it. Чтобы вместо этого подключить диск в пустой папке и он отображался как обычная папка, см. статью Назначение диску пути к папке точки подключения. To instead to mount the drive in an empty folder so that it appears as just another folder, see Mount a drive in a folder.

Если вы измените букву диска, где установлена система Windows или приложения, могут возникнуть проблемы при запуске и поиске этого диска. If you change the drive letter of a drive where Windows or apps are installed, apps might have trouble running or finding that drive. По этой причине не рекомендуется изменять букву диска, на котором установлена система Windows или приложения. For this reason we suggest that you don’t change the drive letter of a drive on which Windows or apps are installed.

Вот как изменить букву диска: Here’s how to change the drive letter:

Откройте модуль управления дисками с правами администратора. Open Disk Management with administrator permissions. Чтобы сделать это, щелкните и удерживайте (или щелкните правой кнопкой мыши) кнопку «Пуск», а затем выберите элемент Управление дисками. To do so, select and hold (or right-click) the Start button, and then select Disk Management.

В оснастке управления дисками выберите и удерживайте (или щелкните правой кнопкой мыши) том, для которого хотите изменить или добавить букву диска, а затем выберите команду Изменить букву или путь к диску. In Disk Management, select and hold (or right-click) the volume for which you want to change or add a drive letter, and then select Change Drive Letter and Paths.

Если вы не видите команду Изменить букву или путь диска или она недоступна, возможно, том еще не готов к назначению буквы диска; эта ситуация может возникнуть, если диск не распределен и должен быть инициализирован. If you don’t see the Change Drive Letter and Paths option or it’s grayed out, it’s possible the volume isn’t ready to receive a drive letter, which can be the case if the drive is unallocated and needs to be initialized. Возможно также, что он не предназначен для доступа; это относится к системным разделам EFI и разделам восстановления. Or, maybe it’s not meant to be accessed, which is the case of EFI system partitions and recovery partitions. Если вы убедились, что у вас есть отформатированный том с буквой диска, к которому можно получить доступ, но букву по-прежнему невозможно изменить, к сожалению, этот раздел, скорее всего, не поможет. Рекомендуем обратиться в корпорацию Майкрософт или к производителю своего ПК за дополнительными сведениями. If you’ve confirmed that you have a formatted volume with a drive letter that you can access and you still can’t change it, unfortunately this topic probably can’t help you, so we suggest contacting Microsoft or the manufacturer of your PC for more help.

Чтобы изменить букву диска, выберите Изменить. To change the drive letter, select Change. Чтобы добавить букву диска, если ее еще нет, выберите Добавить. To add a drive letter if the drive doesn’t already have one, select Add.

Выберите новую букву диска, затем нажмите ОК, а затем выберите Да при появлении уведомления о том, что программы, использующие букву диска, могут работать неправильно. Select the new drive letter, select OK, and then select Yes when prompted about how programs that rely on the drive letter might not run correctly.

How to Change a Drive Letter in Windows

Sometimes when you plug in a USB device, it doesn’t show up

A task you will most likely have to perform a few times in Windows is changing the drive letter for an external hard drive, mapped network drive, or DVD drive. Sometimes when you plug in a USB flash drive, it doesn’t automatically get a drive letter assigned to it and it may not show up on your computer.

In those types of cases, you have to change the drive letter for the device and it will normally pop right up. In this article, I’ll show you how to change the drive letter for these devices using the GUI and also via the command prompt.

Change Drive Letter via Disk Management

You can open disk management on a Windows PC by either right-clicking on the Computer or This PC icon on the desktop and choosing Manage or by clicking on Start and typing in diskmgmt.msc.

You’ll see a list of volumes at the top and the disks and partitions at the bottom. Any partition that has a drive letter will be shown in the white area. If you connected a USB drive and you see it listed, but it doesn’t have a drive letter, you can now assign one.

To assign or change the drive letter for a disk or partition, simply right-click on it and choose Change Drive Letter and Paths.

A window will pop up with the current drive letter, if there is one, and a couple of options. Here you want to click on Change.

Next, you will choose the new drive letter from the dropdown list. You can pick from the letters A to Z.

That’s about it. Click OK to close out all the dialogs and the drive should now show up in Windows with the new drive letter. If you’re having issues using the GUI interface or you simply feel more comfortable using the command prompt, read the instructions below on how to use diskpart.

Use DiskPart to Assign Drive Letter

If you need to change or assign a drive letter via the command prompt, you have to use the diskpart command. I’ve written a bit on how to use diskpart, which is really useful for many disk management tasks.

To get started, open an administrator command prompt in Windows by clicking on Start, typing in CMD and then right-clicking and choosing Run as Administrator.

Now type in the following commands, each followed by the Enter key.

Above, you’ll replace x with the volume number in the list that corresponds to the drive you want to change and with the letter you want to assign to the drive. Here are the commands I ran for an external USB drive:

You’ll also notice that under the Type column, external drives will show up as Removable. That’s a good way to check before you select a volume. You can also figure out which drive is correct by looking at the size and also looking at the Info column. Volume 0 in my case is the system partition, so I wouldn’t want to mess with that by accident.

Overall, it’s a fairly simple process and hopefully you won’t run into any problems. There are times, however, when things don’t work properly. Below are some possible reasons.

Troubleshoot Can’t Change Drive Letter in Windows

One problem that I have seen is that the Change Drive Letter option is simply greyed out. This can occur for a few reasons. One of the main reasons is the volume is not formatted in FAT or NTFS format. For example, if you are attaching a disk from a Mac computer, you will not be able to change the drive letter unless you format the drive into a compatible format.

Another reason is if the drive is set to read-only. If so, you’ll have to Google the steps to change the drive to allow read/write access.

Also, if you don’t need any of the data on the volume in question, a simple solution is to delete the volume, which is normally never greyed out. Once you delete the volume, you can right-click again and create a new simple volume. Now you will be able to change the drive letter.
