Idle Read After Write

Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods,

no active system requests, the drive reads recently written data from the media and compares it to valid write

command data resident in the drives data buffer. Any sectors that fail the comparison result in the invocation of

a rewrite and auto-reallocation process. The process attempts to rewrite the data to the original location. If a

verification of this rewrite fails, the sector is re-mapped to a spare location.
