Abstract: Systems and methods for saving critical data upon power loss are described. In one embodiment, the systems and methods include performing a write operation to a first track of a storage drive, monitoring a voltage level of a storage drive to detect power loss on the storage drive while performing the write operation, identifying a track ID of a second track adjacent to the first track upon detecting power loss on the storage drive, and storing the identified track ID in a non-volatile memory on the storage drive.

Abstract: A method or system comprises determining an end data track of a write operation in response to a request for the write operation in a media storage device, saving data from an adjacent track following the end data track to a cache, performing the write operation. In one implementation, performing the write operation is comprises writing data to a plurality of data tracks in a band.
