Disclosed herein is a data storage device comprising a data path and an access controller. The access controller generates a recovery private key, generates encrypted authorization data based on the recovery private key, stores the encrypted authorization data, and sends the recovery private key to a manager device. When recovery is desired, access controller receives a recovery public key, calculated based on the recovery private key, from a recovery manager device, decrypts the encrypted authorization data based on the recovery public key, generates a challenge for the recovery manager device based on the decrypted authorization data, sends the challenge to the recovery manager device over the communication channel that is different from the data path, receives a response to the challenge from the recovery manager device over the communication channel, and based at least partly on the response, enables decryption of the encrypted user content data.

Recovery key for unlocking a data storage device

Systems and methods are disclosed for validating firmware and/or firmware images. A data storage device may transmit a request to validate a firmware image, to a storage drive. The data storage device may receive data indicating whether the firmware image is valid, from the storage drive. The data storage device may initiate operation using the firmware image if the firmware image is valid.

Validating firmware for data storage devices

Systems and methods are disclosed for programming non-volatile storage. Methods involve identifying boot loader code stored in a first partition of a non-volatile storage, the boot loader code being marked as active, executing the boot loader code using one or more processors of the computing system, loading a firmware image to a second partition of the non-volatile storage, the second partition being separate from the first partition, and marking the firmware image as active. Methods further involve detecting a power loss event and, following a power cycle, determining that the firmware image is stored in the second partition and has been marked as active, and, in response to said determination, making a copy of the firmware image and storing the copy in the first partition.

Memory programming providing corruption protection

Systems and method are disclosed for processing data storage commands for enclosure services. In one embodiment, a data storage device may include a virtual ATA packet interface (VATAPI). The VATAPI may identify itself as a SCSI enclosure services (SES) device. The VATAPI may allow the data storage device to use SES operations/commands to perform operations/commands for enclosure services.

Processing data storage commands for enclosure services

A host including a controller configured to be connected to a storage device separate from the host. The controller is configured to maintain random access memory (RAM) code on the host, the RAM code configured to provide a destructive function, temporarily load the RAM code onto a volatile memory in the storage device during a manufacturing process, wherein the loaded RAM code, when executed by a processor in the storage device, is configured to cause the processor in the storage device to perform a destructive function on the storage device, and remove the loaded RAM code from the volatile memory after the manufacturing process, wherein the destructive function is unable to be performed by the processor when the loaded RAM code is removed from the volatile memory.
