Abstract
Unrecoverable electronic correction code (ECC) errors in memory storage devices are usually preceded by recoverable ECC errors. A memory storage device controller is provided notice of the recoverable errors and associated information. The memory storage device controller can cause the data having the recoverable information to be rewritten on the memory storage device. Rewriting the data on the memory storage device (often in a different location) normally reduces the probability of encountering data with unrecoverable data errors.
