Problem while trying to format harddrive
I am trying to reformat my harddrive so that i can install xp pro. When i try to format it i get " Format cant run because the volume is in use by another process. Format may run if this volume is dismounted first. ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID. Would you like to force a dismount on this volume? (Y/N)" So i typed y and then I get "Cannot lock the drive. The volume is still in use." Does anybody have an idea of what I should do?
