Windows hides a drive when you remove its drive letter in diskpart or apply the Hide these specified drives policy. Both methods remove the drive from File Explorer. Neither method blocks access because the data remains on the disk. Use BitLocker or NTFS permissions when you need real protection.
You may want a drive to disappear from File Explorer so family members or coworkers do not browse it. Windows has two built in ways to do that.
Hiding a drive is not the same as protecting it. This guide shows both methods and the step that adds real protection.
What are the Ways to Hide a Drive in Windows?
| Method | What it Does | Blocks Access |
|---|---|---|
| 1. diskpart remove letter | Removes the drive letter from the volume | No |
| 2. Group Policy hide drives setting | Removes the drive icon from File Explorer and the Open dialog | No |
How do You Hide a Drive With diskpart?
Microsoft documents remove as the diskpart command that removes a drive letter or mount point from the volume that has focus. You must select a volume first. See diskpart remove.
- Open Command Prompt as administrator.
- Enter diskpart and then list volume.
- Select your volume by number.
- Remove its drive letter.
diskpart
list volume
:: Replace 3 with the number of your volume
select volume 3
:: Replace D with the letter you want to remove
remove letter=d
exitMicrosoft states that you cannot remove drive letters on system, boot or paging volumes. Choose a data volume only.
How do You Show the Drive Again?
Select the same volume and give it a letter. Microsoft documents assign for this task. If the letter is already in use the command returns an error, so choose a free letter. See diskpart assign.
diskpart
list volume
select volume 3
assign letter=d
exitHow do You Hide a Drive With Group Policy?
Microsoft describes the policy Hide these specified drives in My Computer under User Configuration, Administrative Templates, Windows Components and File Explorer. It removes the drive icons from File Explorer and from the Open dialog box of programs. See Microsoft guidance on hiding drives.
Policy values use one bit per drive letter. Letter A has the value 1 and letter D has the value 8. Select the option for the drives you want to hide.
Does Hiding a Drive Protect Its Data?
No. Microsoft states that this setting does not prevent users from using other programs to reach local and network drives. It also does not stop users from viewing drive properties in Disk Management.
Microsoft points to other controls such as NTFS permissions when you need to block access. BitLocker encrypts a whole volume to protect data if a device is lost or stolen.
