Abstract
A storage system having a plurality of disks arranged into a RAID array and a logging process and apparatus that identifies corrupt or invalid data and which prevents the corrupt or invalid data from being sent to a user application or used in any computations internal to the functioning of the array. In the preferred embodiment, a plurality of status bits, each having a first and second state are associated with each data block and parity block. If the status bit indicates that the block may contain corrupt or invalid information then that block is not used in regenerating data for an unavailable block or sent to a user application upon a read request.
