need some quick help... i'm reinstalling xp on a friends machine and when it got done (upgrade version) the hard drive had an icon that xp uses for unrecognizable file..and i couldn't double clip to open it...though if i right clicked and pressed open it works fine... it knows its a hard drive... also theres a partition, that works fine. i tryed reinstalling xp and reformatting, it did it to the partition...which is fine i wanted it reformatted and xp installed on it...but it didn't do anything to the main partition... same problem. i tried reformatting it by right clicking and pressing format...it tries and by the end says it is unable to format how do i reformat it? or solve this problem? i don't care if the end result is to get rid of the partition..and reinstall xp.. thats fine..i jsut want to wipe everything clean and restart..what is the best way?
