Splendid. It sounds to me like you have some sort of more serious problem, because Windows should be able to boot and run fine on a RAID 5 array even while it’s rebuilding. It will be SLOW, but it should work. CHKDSK won’t help – it only works on the file system, not the underlying RAID configuration.

Should you run chkdsk on RAID?

Chkdsk is a filesystem utility primary and all file system actions work just fine on RAID. The scandisk functionality rolled into NT’s chkdsk should just return no results, don’t use it, but it shouldn’t be a problem – the array will hide the actual disks from the utility.

How do I check my RAID hard drive status?

To view the RAID status, go to System Settings > RAID Management. The RAID Management pane displays the RAID level, status, and disk space usage. It also shows the status, size, and model of each disk in the RAID array.

Can I run chkdsk on a RAID controller?

A RAID controller offers a logical construct to the OS which appears as a drive, there is no greater nor lesser reason to run CHKDSK on such. Theoretically, and normally, physical errors on the HDDs are detected by the RAID itself and the mechanical side of failure is dealt with by the RAID controller.

How do I run chkdsk on boot?

If Y is pressed, the utility will try to close all open handles and locks on the volume. If it is successful, chkdsk will run. If it is not successful, you will have the option to set autochk to run on boot (see running chkdsk on boot volume).

Why is CHKDSK not working on my array?

In some instances, you may need to run the command multiple times to repair all corruption. Try to avoid running on a degraded array – chkdsk is NOT raid aware and can cause issues. Never run on an array that is in the rebuilding state.

Why does CHKDSK need to be restarted every time?

(Y/N) Chkdsk needs exclusive access on a volume and since the boot volume contains operating system files, a restart of the computer is necessary to run chkdsk before the files are accessed and locked by the operating system. As an alternative, Recovery Console can be used to run chkdsk to get exclusive access to the volume.
