DATA STORAGE DEVICES AND METHODS FOR POWER-ON INITIALIZATION

摘要

Methods and systems are disclosed to generate a data map for a data storage device. A data map may be generated by scanning, during a power-on initialization process, data units of data stored on a data storage medium of a data storage device. The scanning may start from a selected data unit and proceed through the data units in an order opposite to a write order to identify a first data unit that is not fully erased. Also. an error recovery status of the first data unit may be determined based on an error correction code. A likely erased status of the first data unit may be assigned when the determined error recovery status is unrecoverable.
