The hard disk drive contains pre-loaded software. Be
sure to reload the software on the primary hard disk
drive (Drive C) when replacing it.
IMPORTANT: The drives in the system you are
servicing may have been rearranged, or the
drive startup sequence has changed. Be
extremely careful during write operations, such
as copying, saving, or formatting. Data or
programs can be overwritten if you select an
incorrect drive. Ask the customer to back up
any additional software from the hard disk
drive before you reload the software.
How to Diagnose Combined FRUs: If an adapter or
device consists of more than one FRU, any of the
FRUs might cause an error code. Before replacing
the device or adapter, remove the FRUs one by one
to see if the symptoms change.
If a newly replaced FRU does not correct the
problem: If you have reached this point of the check
procedures and were instructed to replace a FRU but
doing so did not correct the problem, reinstall the
original FRU and go through Start again.

READ THE FOLLOWING:
Human Error is a cause for concern when applied
to check procedures. It exists in every first time
set of analysis procedures. It is therefore
essential for effective and time-efficient servicing
that each stage of every procedure be verified.
(For example: When a symptom is found, or when
a symptom appears to have been cured; the
preceding steps should be repeated for accuracy
of analysis.)
