Abstract
A host processing system includes a processor, a RAID controller, and a data storage device coupled to the RAID controller and operable to detect first unrecoverable data at a first logical block address (LBA) of the data storage device, log the first LBA in an unrecoverable LBA table of the data storage device, provide the unrecoverable LBA table to the RAID controller, and in response to receiving a write to the first LBA, remove the first LBA from the unrecoverable LBA table.
