Abstract:
A method for providing for write once read many (WORM) times from at least some addresses of a storage drive that is otherwise manufactured for multiple writes to individual addresses. In at least one embodiment, a WORM area(s) is defined by a START_LBA and an END_LBA and the method uses a HWM_LBA to determine whether a LBA in the WORM area has been written to previously and to prevent previously written to LBA(s) in the WORM area from being rewritten. In at least one embodiment where there are multiple WORM areas, each WORM area has its own respective START_LBA, END_LBA and HWM_LBA.
