Would a methodology that'll do
if read error then
recreate the block from parity
write to sector that had read error
wait until write has completed
flush buffers
read back block from drive
if block still bad
fail disk
log result
This would give the drive a chance to relocate the block to its spare
blocks it has available for just this instance?
If you get a write error then the drive is obviously (?) out of spare
sectors and should be rightfully failed.
