RAID Volume Missing in Windows* Disk Management but Intel® RST Shows All Disks

When reviewing the RAID 5 status on Disk Management, the volume is missing; however, in the Intel® Rapid Storage Technology (Intel® RST) all disks are visible.

When the available information shows that everything is fine under Intel® RST and not in Windows*, it should not be an Intel® RST issue, but these may be early indications of a failing volume.

Intel recommends to verify and repair, to see if the discs and arrays are fine.

Verify and repair volume feature

The RAID volume verification feature identifies any inconsistencies or bad data on a RAID 0, RAID 1, RAID 5, or RAID 10 volume and reports the number of inconsistencies or number of blocks with media errors found during RAID volume data verification.

When the verification process is complete, a dialog will appear that displays the number of verification errors, verification errors repaired, and blocks with media errors that were found.

1. Under Status or Manage click the RAID volume you want to perform the verify operation under storage system view. The volume properties now display on the left.
2. Click Advanced’ and then click Verify.
3. For RAID 0 the verification process starts once you click Verify. For RAID1, 5, 10, Recovery volumes, a dialog box with checkbox option is present to repair the errors found automatically during the verification process. If the you want to perform repair, select this box and then click verify’
4. The verification progress is shown under Status

Under the volume properties to the left under Advanced you can view the number of verification errors, verification errors repaired, and blocks with media errors that were found.
