ABSTRACT:
A system for detecting write errors in a storage device is disclosed. The system comprises a storage device; within the storage device, means for storing one or more data blocks in a storage group, the storage group comprising the one or more data blocks and a check block, wherein the check block comprises one of the group of: a combination of the one or more data blocks of the storage group, a combination of one or more bits of a logical block address associated with the storage group, and a combination of one or more bits of a phase field that is updated each time the storage group is written; means for updating the check block each time the storage group is written; and means for detecting write errors by checking the check block.
