ABSTRACT:
Method, system and computer program product for reporting and recovering from uncorrectable data errors in a data processing system using the Advanced Technology Attachment (ATA) or the Serial ATA (SATA) protocol. The invention utilizes the data scrubbing functionality of SCSI hard drives to provide a higher level of data integrity in an operating system implemented RAID environment. If an uncorrectable data error is found on a hard drive during a background data scrubbing operation, information concerning the data error is logged in a S.M.A.R.T. (Self Monitoring Analysis and Reporting Technology) error data structure. When the host operating system identifies the uncorrectable data error during normal operation, a Host Array Manager issues a Write Command to write the data from a redundant drive after the defective Logical Block Address (LBA) has been reassigned.
