There is no support from the manufactures for service for these drives.
They are considered disposable, especialy when considering value of the
labour cost, and the setup to be able to service these.

The only thing you can do for yourself, is to open the drive unit, and
see if there is anything that you can mechanicaly fix yourself.

If you have some basic service skills, you can look to see if there are
any loose connections, or if something is mechanicaly jaming., or if
there are any visible cold solder connections.
