Full format won't check for errors any more than a quick format surely?
I would have thought
format "drive letter"
would have done the trick from a command prompt however.
I wouldn't bother personally, as a decent amount of use after a quick format will have deleted everything on the drive previously before too long.
disk 0 is about the right size for a Linux swap partition ...have you ever had Linux on that disk ? ...as for Windows though ...I dunno, W7 will typically place a 100MB partition at the start of the disk but not one of over 7GB ...unless the computer was an off the self one in which case it could be a restore partition.
To answer your question.
If your so paranoid about the full format thing. Download "Gparted" Burn the .iso to a disc. Boot from the disc (you can also use universal usb installer and boot off the usb like you have been doing) You will then see your hard drive there and you can format it anyway you like. It's a lot more stable and versatile than Windows built in commands.
If you then want to check for errors or check the health status of the disc. Run your manufacturers diagnostics utility on it. If it passes, stop freaking out and juse use the thing. Seatools for dos is really good (even if you dont have a seagate).
Now. If you continue to cry about the format C: volume label and want to check for errors using DOS. Well... I vote for you to be banned!
Looks like he forgot about this thread and decided to make a whole new one on what is the command for 'format C'. Can anyone say spam?
