Hi, I'm working on a computer and hooked up the drive on another computer to run a check disk. It said I needed to force a dismount before it could continue. I looked this up and everyone seemed to say to do so, let it run, then restart the computer. I forced the dismount, but then nothing happened. It just shows a drive is there, but if you try to do anything to it, it says the drive needs to be formatted before I can use it. Please help.
