so i just bought and installed a new hard drive. i wanted to switch this drive to my master boot drive, cause my old drive was seriously fucked up. so i installed windows xp on it, switched it to my master boot drive, and now everything is working fine, BUT i want to reformat my old drive and clean it completely. but when i right click -> format drive... it says its unable to complete the format. it wont give me a reason. im not runnin my os from that drive. its completely empty now. any ideas whats going on or how i can format it? thanks.
