I'm no drive expert, but this may cost as much as the drive itself.
For ten years, "Winchester" disks have been manufactured as disposable
technology.  Here's why it might be cheaper to throw away the drive --

(1) The inside of the drive is like a clean room, with only so many
ppm of particulate matter.  This must be maintained, and the drive
must be re-tested ($$$) when the repair is complete.

(2) Have you ever tried to open a motor to change the grease?  I
thought you hadn't.
