摘要： A data validation method comprises associating a validation chunk with one or more data chunks stored on one or more storage mediums. The validation chunk comprises validation information for verifying whether data recorded in a subdivision of the one or more data chunks is lost. A request is received for an operation to be performed on first data stored in a first subdivision of a first data chunk from among said one or more data chunks. One or more portions of the validation information are examined to determine whether the data recorded in said first subdivision is deemed to be lost.

摘要： A write error detection mechanism for a computer data disk drive or storage controller writes and then verifies data to detect disk write errors. It allows the heads to be moved to other tracks to do other jobs in the time it takes the disk to rotate from the point the data was written and to return there again so it can be read to verify the write. The data written is temporarily stored in feature table memory outside the disk, so it can be used as in the comparison later when the written data can be read for the verify. In the interim, other write-and-verify and read operations can be pipelined, or multitasked using the same head, even on different tracks.

摘要： A storage controller and associated disk or disk portion where after the controller terminates its access to said disk or disk portion, data integrity problems in the disk or disk portion can be detected. Before host data associated with a write command is written from the cache memory to the disk or disk portion, an identity of the storage controller as a current user of the disk or disk portion and indication that the controller is operating in a mode it stores data in a cache is recorded on the disk or disk portion. If the storage controller is shut down abnormally, the record of the identity of the controller and the indication are not cleared. The storage controller is restarted or rebooted and the record is read to learn that the controller was using the disk or disk portion and operating in the foregoing mode before the shutdown.
