I guess what you are asking is: With raid5, I would like the drive to handle a read request by reading all the blocks in the stripe and checking the parity. If the parity is correct, return the data blocks. If it is not, then fail the read request. Is that possible? No, it is not. If you are really asking something else, please be more specific.
