repaired. As a result, you no longer have to synchronize
RAID level 1 and RAID level 5 logical drives on a weekly

redundancy for the logical drive is correct. For RAID
level 5, the parity bit is computed and then written to the
parity drive.
To synchronize a logical drive:
1. Select the logical drive that you want to synchronize
from the Main Screen of the Administration and
Monitoring utility program.
A screen similar to the following appears.

2. Click on Synchronize to synchronize the drive.
