Ok, i've done this a hundred times, but its giving me trouble now. I want to reformat, so I open up DOS and type in "Format C:" --- then I get this message. "Format cannot run because the volume is in use by process. Format may run if this volume is dismoun ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE IN Would you like to force a dismount on this volume?" --- Then after I hit yes, it says "Cannot lock the drive. The volume is still in use." How do I format?!?!
