• Disconnect the drive from your computer.
• Look closely for a lock/unlock slider.
• Place it in the unlock position, then reinsert the drive.
• Try using DiskPart again.

If the switch is already open, proceed to software-based repairs.

Method 2: Run Command Prompt as Administrator

This error is mostly the result of not running DiskPart with admin rights.

2. Windows Win+X Command Prompt → Run as administrator

Enter the following commands:

• diskpart
• list disk
• select disk X   (replace X with your disk number)

attributes disk clear readonly

The output should remove the read-only attribute if the command runs. If not, proceed with the registry and group policy ways.

Method 3: Use Windows Registry Editor

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

1. In the right-hand panel, find WriteProtect.
2. Double click this and put Value Data = 0
3. Restart your system.

Computer Configuration > Administrative Templates > System > Removable Storage Access

1. Search for entries like Removable Disks: Deny write access.
2. Finally, double-click and set the entries to Disabled.

After all these are done, restart your system and try opening DiskPart again.

Method 5: Check Disk Errors with CHKDSK
