ABSTRACT:
Method and apparatus for sending data from a disk drive as that data is being read. Error correction and checking is performed after the data is sent, followed by a calculation and transmission of communication cyclic redundancy check information. If error correction and checking identifies a problem, corrected replacement data is determined and sent. Data off-sets can be sent to inform the host system where the corrected data is to be applied.
