RAID Volume Data Verification and Repair
The RAID volume data verification process identifies any inconsistencies or bad
data on a RAID 0, RAID 1 or RAID 5 volume. The table outlines what occurs for
each RAID level:
Replacing and Reverting Recovery and Master Volumes
If a master or recovery drive fails you will need to add a new identical drive and re-
build the recovery volume to the drive. You can also revert the master drive to the
state of the previous volume update. For details on how to do this see the help file
“Intel® Rapid Storage Technology Help” on page 7 - 11 .See over for details on
how to verify and repair RAID volume data. Verification will identify and repair
data inconsistencies on the volume.

RAID 0 Bad blocks are identified. N/A
RAID 5
Bad blocks are identified.
Parity is recalculated and compared
to the stored parity for that stripe.
Bad blocks are reassigned.
If the newly calculated parity does not match the
stored parity, the stored parity is overwritten with the
newly calculated parity.
RAID 1
Bad blocks are identified.
Data on the mirrored drive is
compared to data on the source
drive.
Bad blocks are reassigned.
If the data on the mirrored drive does not match the
data on the source drive, the data on the mirrored
drive is overwritten by the data on the source.
