SP1 didn't do any good. Well, not with this problem, but it really helps with Vista.
System restore? Dude. Thats a little out of the question. I don't have the time or the patience to do that. I would be better off looking for a different drive.
Speaking of which, how about this drive: http://www.newegg.com/Product/Produc...82E16827151161
Its IDE, which I need (I would go for SATA, but I would rather have IDE since I will have an open IDE plug if I get rid of my problem drive), its cheap, it has good reviews, and comes from a good brand/ site.
