Windows – USB Drive is Read Only

I attached a USB drive to my Windows 2008 server today and when I went to copy a file to it, the drive is “write protected”.

I didn’t see a way to undo this readily and I’m not sure how it happened in the first place, but the following commands worked:

  1. Start a Command prompt with elevated administrator access
  2. Type the following commands:
    1. DISKPART <ENTER>
    2. LIST  VOLUME <ENTER>
    3. SELECT VOLUME X <ENTER> (where X is the USB drive)
    4. ATTRIBUTES DISK CLEAR READONLY <ENTER>
    5. EXIT
  3. Close the command prompt

This worked!
