Hello. I have two HDs in my PC, one for the OS and one for backup... the OS one died randomly yesterday so I'm going to be converting my current backup HD to my primary one and just get a backup HD... kind of worried of this happening again except on my backup stuff. This is the one I've been looking at: AcomData PureDrive 500GB http://www.canadacomputers.com/index.php?do=ShowProduct&cmd=pd&pid=018858&cid=HD.342 Good? Bad? Recommendations please?
