Ahh... you do know that the IBM DeskStar drives
have a huge failure rate.  There was a processing
error in the manufacture of drives during those
years.  Major PR problems for IBM, class action suit
and they sold the drive division after that.

If you still have data on them that you want to keep
you should copy them else where.
