Was transferring 6 or 7 gigs of wmv files from one drive to another. Giving drive is fat 32, receiving drive is ex-fat. While in process, started another explorer to look for something else. System hung, would not relieve. Had to re-boot to get moving again. Ex-fat drive
became read-only (not thru MY choice).
Have tried 'diskpart' in command prompt, with seeking volume #, then typing "attributes disk clear readonly" with no success.
Rebooted & tried command prompting again, with no removal of read-only. Can copy off, but have 1.2TB full on a 2TB drive.
