I would advise that whatever you replace it with, avoid a Maxtor as I have read horror stories on this board and heard from other sources about how lousy they are. I have one in my PM, but it hasn't been used for very long, so I am unable to advise based on personal use. However, I have had good luck with IBM drives, so I don't think that you can go wrong there. But hey, all mechanical things are capable of having or developing defects, whatever you buy 😉
