It all starts with that strange sound… In my machine’s case, a whining noise.  As a sysadmin and/or experienced geek, you know something’s wrong.  I suspect the head assembly has become detached and is scraping along the disk surface at 7200rpm…

Naturally, the usual recovery tools don’t work… and the drive sounds shot.

This is the third 1TB Seagate ES.2 drive I’ve had develop bad sectors.  Although they have a 5 year warranty, they seem to start expiring after 3.

Thank goodness I have backups…
