A few months ago I was using this Maxtor 80GB HDD (PATA, 7200, about 2-3 yrs old). After I received my 300GB drive I gave my dad the 80GB HDD. He already had a 120GB installed in his PC so he installed Vista RC1 on the 80GB to try it out. Well, I needed the drive back again a few months later since I'm currently running on 5GB and when I hooked it up my PC would not detect it. So, since it was last working on my dad's PC, I hooked it up to his, now it is not even being detected on his. I've also tried disconnecting all my HDDs and let the 80GB run alone, still wasn't detected. The drive still has Vista on it. I am clueless on how to solve this problem, if it can indeed be solved. Thanks for any help.
