I can't really afford to get a new computer right now, so I decided to frankenstein 3 comps that I have. I decided to install WIN XP on the computer, it used to have 2000. Pre XP my 20 gig hard drive worked fine. After XP I get a message that hard drive is unformated or unrecognizable format. Hard drive is Fat32. Hard drive also used to work just fine on another comp with xp. Any idea how I can get the new XP machine to recognize the HD?
