Fix: The Disk Is Write-Protected error for Removable Disks

We all use removable disks in Windows. Well, sometimes, you may came across such errors with these removable disks, that may make you believe that  the disk has malfunctioned and can’t be used at all. Today, in this article, we’ll discuss on such scenario I recently faced with a USB Drive. Actually, whenever I plug that drive and perform any operation with this drive results in following error:

The disk is write-protected. Remove the write-protection or use another disk.

Obviously, the Try again button shown in above error box does nothing significant to fix the hitch. Due to this, you might feel that the disk is not usable and you should throw it to dustbin. But wait! If you’re really going to do so, why not try something to make this disk again this writable. Here are the two fixes you can try to make your USB drive working again:

The Disk Is Write-Protected

FIX 1

1. Press Windows Key + R combination, type put regedit in Run dialog box and hit Enter to open the Registry Editor.

2. In the left pane, navigate here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

3. In the left pane of this location, right click Control key and select New -> Key. Name the new sub-key so created asStorageDevicePolicies. Now come to the right pane of this sub-key i.e. StorageDevicePolicies, right click and select New-> DWORD Value. Name the newly created DWORD as WriteProtect. In some cases, you might find that this DWORDunder the sub-key already exists and the DWORD has a Value set to 1. Double click on the DWORD to modify its Value data:

4. In the above shown box, change the Value data to 0 from 1. Click OK. Close the Registry Editor and check if the issue is resolved, else try FIX 2 mentioned below.

FIX 2

1. Open administrative Command Prompt.

2. Type these commands one by one and press Enter key after each:

diskpart

list disk

select disk # (# is the number of USB drive with which you’re getting error and is plugged in, see screenshot below)

attributes disk clear readonly

You may now close Command Prompt and re-plug the USB drive and check if the issue is resolved. If the disk is still showing same error, there could be a possibility that the chip-set of this drive is broken.
