Restore Access to a Write-Protected Hard Drive

1. Open a Command prompt.

2. Type diskpart and press Enter.

3. Type list volume and press Enter.

4. Type select volume #, where # is the number of the drive that's giving you the "write-protected" error. In my case, I ended up typing select volume 3.

5. Type attributes disk clear readonly and press Enter.

6. Type exit and press Enter.

You should have full write access to the problem drive.
