9. TROUBLE SHOOTING
9-19
(22) HDD rebuild occurs..
<Possible cause>
If there is no response from the HDD above a certain level and the timing of the system
power off overlaps, rebuilding may occur in rare cases even if the HDD is not replaced.
1. There is no problem if the rebuild is completed normally due to a transient failure.
2. If it occurs repeatedly or if an HDD error is detected in the hardware status display
window, it is considered a drive failure and it is recommended to back up the HDD data
and replace the HDD.
