oK, so what we'd like to do is get the backup RAID volume back in
working order. You said it's made of 2TB Caviar green drives, but
didn't mention the RAID controller type... As I understand it, you
power-cycled the RAID array, so the cache is gone, whatever have been
in it...
All arrays I know will happily reassemble a working RAID if you
succesfully revive the failed drives.
Logically the failed drives are almost certainly not really dead, but
in a temporary failure state mode. First, you must check WD support and
utilities to see if something may apply to your configuration. Anyway,
checking the failed drives' health with the western digital disk
utility should allow you to determine if they're toast or not.
In the case they're not actually dead, you could try to revive the
badblocks with Spinrite (www.grc.com), it saved my life a couple of
times, however it's quite risky when used with SMART-tripped drives.
