1.3.3 Troubleshooting at factory

When the trouble is recovered by replacing the drive at field (Subsection 1.3.2),
troubleshoot the replaced drive to isolate the trouble to the subassembly parts.
To shorten the troubleshooting time and repairing time, gather the data, such as
environmental data and other information, from the user and then return the failed
drive to the factory with the media defect list to repair.
At the factory, user environment is made and a reappearance test is performed.
To reappearance a same trouble at user, the failed drive is connected to the host
system. If no trouble occurs by the normal test, the reappearance test is
performed by adding the voltage/temperature load using a disk drive tester or
tools according to the user environment.
When a trouble reappeared, troubleshoot the cause of failure. Then, replace the
failed unit or parts.
As this level maintenance is made by a factory, this maintenance level is beyond
