RAID Volume Data Verify and Repair
| Note | Review this information on recovering a RAID 0 volume failure using Intel® Rapid Storage Technology. |
Why should I do verification and repair on data?
The RAID volume data verification process identifies any inconsistencies or bad data on a RAID 0, RAID 1, RAID 5, or RAID 10 volume.
The RAID volume data verification and repair process identifies and repairs any inconsistencies or bad data on a RAID 1, RAID 5, or RAID 10 volume.
The following describes what occurs for each RAID level:
| RAID Level | Verify | Verify and Repair |
| RAID 0 | Bad blocks are identified. | N/A |
| RAID 1 | Bad blocks are identified | Bad blocks are reassigned. |
| Data on the mirror drive is compared to data on the source drive. | If the data on the mirror drive does not match the data on the source drive, the data on the mirror is overwritten with the data on the source. | |
| RAID 5 | Bad blocks are identified. | Bad blocks are reassigned. |
| Parity is recalculated and compared to the stored parity for that stripe. | If the newly calculated parity does not match the stored parity, the stored parity is overwritten with the newly calculated parity. | |
| RAID 10 | Bad blocks are identified. | Bad blocks are reassigned. |
| Data on the mirror is compared to data on the source. | If the data on the mirror does not match the data on the source, the data on the mirror is overwritten with the data on the source. |
