Hey dvl,
I've had similar problems.  This has come up a few times on the mailing
list in the past, especially regarding certain lines of IBM drives.
Suggestions include replacing your IDE cable, making sure it's not longer
than 18 inches...and replacing the drive as it's probably on its last leg.
Back it up while you can.
