I've got a second disk installed on my new desktop that I am trying to format, but nothing is working. I tried running the format command from the command prompt and it said "Format cannot run because the volume is in use by another process. Format may run if the volume is dismounted first. ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID. Would you like to force a dismount on this volume?" I said yes "Cannot lock the drive. The volume is still in use." I then tried rebooting the system and got the same result. I also tried formatting it from Windows Explorer, but got an error message that says "Windows cannot format this drive. Quit any disk utilities or other programs that are using this drive and make sure that no window is displaying the contents of this drive. Then try formatting again" Where do I go from here?
