Solved: Degraded RAID 1 Volume : how to ID the failed disk

steveb_online · ‎01-16-2023

I am not very savvy about RAID volumes, so apologies for any stupid questions.

I am running a GIGIBYTE MB with two identical SSDs in RAID 1.

My PC has started to boot VERY slowly and the BIOS does not see one of the drives as a bootable device (as it used to before the problems emerged) although it sees both drives on the SATA controller.

I had a look at the RST utility and it reports a degraded volume. Both the SATA disk are show as "OK" on the "Manage" page and I can see their ID's OK. Screenshot attached.

I cannot "see" both the SSDs in Windows Devices or SeaTools to do a SMART check.

No Events were recorded for the RAID array by the Windows 10 OS

I have the option to rebuild the array but here's the thing...

How do I determine which drive is the one that should be used as the master?

What happens if I select the wrong drive to be rebuilt?

If I buy a new (identical) SSD drive to rebuild the array, I still have the same problem. Which is the master drive that should be used to rebuild the array?

Any help would be appreciated. It is quite probable that I have the wrong end of the logical stick.

Thanks

SOLVED

Having opened the PC case and probed around a bit, I see that I can ID the drives from the SATA ports they are connected to. I wasn't confident that I would be right but, having shut down the PC and disconnected the drive I ID'd as being the one that had died, the PC restarted OK and confirmed my suspicions. I tried the removed SSD in a remote connector to test the drive and it is definitely dead. Regrettably it went out of warranty 6 months ago. I am now waiting for a replacement drive to be delivered.
