I have philosophical question about the RAID software.

I think you are right.
After a read error, the raid system would do well to:
  read a few other random blocks on the drive
    (first/last/middle/superblock) to see if the whole drive is dead
    or not
  Updates a failed-read-count in the superblock - abort if this fails
  regnerate the data from redundant info
  attempt a re-write
  On success assume the device has coped.

All we need now is code .... are you offering?
