Abstract: Torn write mitigation circuitry determines if a write operation to memory is in progress at or about a time of power loss. In response to the write operation being in progress at or about the time of the power loss, the torn write mitigation circuitry causes torn write data and metadata to be stored to a non-volatile cache. The torn write data comprise data left in a degraded or uncorrectable state as a result of the loss of power. The metadata describe the torn write data.

Abstract: A plurality of aligned or unaligned data packets are received in a data storage device. A data bundle is constructed by concatenating different ones of the plurality of unaligned data packets. Data loss protection identifiers are utilized to track the construction of the data bundle. The data loss protection identifiers are employed to prevent at least one of packet data loss or metadata loss in response to detecting a state reset of the data storage device.

Abstract: An imminent state reset of a data storage device is detected. In response to determining volatile data of the data storage device could be lost in response to the state reset, the volatile data of the data storage device is stored to a backup memory of the data storage device together with first header data that facilitates recovering the volatile data. The backup memory includes non-volatile, solid-state memory. In response to determining the volatile data would not be lost in response to the state reset, second header data is stored in the backup memory. After the state reset, a recovery of the volatile data from in the backup memory is attempted if the first header data is detected, or a host device is alerted if neither the first header data or second header data is detected.

Abstract: Physical subsector error marking allows for selectively marking subsectors of a physical sector of a storage medium as unreadable. The error marking may include a bad sector mask to indicate that the subsector is unreadable combined with an error signature to confirm that the bad sector mask was set intentionally. The remaining readable subsectors of the physical sector may be returned to the host.
