USB Disk read only

If you unplug an USB disk while it’s in use, or I can image in thousands of other situations, it’s possible that the system recognizes that unit as read-only disk, and replug the disk or reboot the machine doesn’t solve the problem.

So here they are some commands to regain full access to the disk:

Open a DOS prompt and use diskpart command:


DISKPART> list disk

Disk ### Status Size Free Dyn Gpt
——– ————- ——- ——- — —
Disk 0 Online 1862 GB 0 B
Disk 1 Online 465 GB 1024 KB

DISKPART> select disk n (where n is the readonly disk)

 Disk n is now the selected disk.


A message will confirm the success of the operation.
