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 translation: 检测到数据存储装置的即将状态复位。 响应于确定数据存储设备的易失性数据可能会响应于状态复位而丢失，数据存储设备的易失性数据与有助于恢复易失性的第一报头数据一起存储到数据存储设备的备份存储器 数据。 备份存储器包括非易失性固态存储器。 响应于确定易失性数据将不会因状态复位而丢失，第二标题数据被存储在备份存储器中。 在状态复位之后，如果检测到第一标题数据，则尝试恢复来自备份存储器中的易失性数据，或者如果没有检测到第一标题数据或第二标题数据，则主机设备被警告。
