You might search around for the TLER utility. TLER ("Time Limited Error
Recovery") is the feature on their RAID Edition (RE) drives that limits the
time that they will spend attempting to read/write a bad sector to 7
seconds. The idea is to tell the controller that the sector is bad and let
it recover it based on redundant data, rather than have the whole drive
drop.I haven't played with WD's absolute latest drives, but you could run the TLER utility on their older desktop-line drives to enable it. All 12 of the WD5000AAKS drives in my RAID6 array have the TLER set to 7 seconds.
