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?
