Abstract
Disclosed is a method and apparatus relating generally to analysis techniques for data integrity following an un-safe power down occurrence of non-tape media components comprising a storage system. The data storage system comprises at least one random access memory storage device adapted to be power cycled in at least an on and off condition. The random access memory storage device comprises at least one storage medium comprising a first stored data segment. The storage device is adapted to receive data for storage on the medium in at least a second data segment. At least one state bit has a first state associated with the second data segment during the storage of the second data segment and a second state associated with the second data segment after completion of the storage of the second data segment wherein the state bit is stored in non volatile memory associated with the storage device. The state bit is capable of being accessed to determine completion status of the storage of at least the second data segment after the storage device is power cycled in the on condition.
