    Abstract: An implementation of a system disclosed herein provides an apparatus, comprising a system on chip, wherein the system on chip is configured to receive a sleep command from a host and in response to the sleep command, calculate a primary checksum of a block of data from a low latency memory such as a tightly coupled memory (TCM), copy the primary checksum and the block of data into a volatile storage media, preserve interface variables of the system on chip in the volatile storage media, operate the volatile storage media in a self-refresh mode, and shut down power to other components on the system on chip.

    Abstract: A data storage device that includes a data storage medium and a controller communicatively coupled to the data storage medium. The controller is configured to receive commands from a host and to detect a hung state in the data storage device. The controller is also configured to determine an execution status of a command, of the commands from the host, associated with the hung state. The controller is further configured to dynamically carry out a self-recovery operation in the data storage device to clear the hung state. The self-recovery operation includes steps that depend upon the execution status of the command associated with the hung state.

    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.
