Shortly after a power outage, one of my drives was unable to mount giving a Buffer I/O error logical block 0, async page read.

Run a long test on the drive, also worth replacing cables and posting new diags after doing both.

Can't seem to run a long test as it won't let select the drive. Replaced cables and card and still won't show up.

If the drive doesn't show up not much you can do, you can swap cables with a known good one, if it still doesn't show up it's likely dead.
