I have a HP Pavillion machine, and I'm using the RAID controller built into the motherboard (H-RS880-uATX, some consumer grade RAID controller, not sure who).
I got a slew of event log errors from the AMD RAID API the other night. I ran a SMART test from the BIOS on both drives and the second drive failed on reads.
I think the right answer here is to break the RAID array, to run off a single drive for a while, buy a new drive to replace the drive that is failing SMART testing, and rebuild the mirror.
However, I'm not sure, so I'm asking. It would be nice to salvage the second drive if possible. Could I run a checkdisk on it and continue using it as part of the RAID array? What about as an extra non-RAID data disk?
