Abstract
A Data Storage Device (DSD) includes a disk for storing data, a volatile memory for temporarily storing data to be written on the disk, and a Non-Volatile Solid-State Memory (NVSM) for storing data. Data is stored in the volatile memory in preparation for writing the data on the disk. The data is written from the volatile memory onto the disk, and it is determined whether the data written on the disk is qualified as written. In the event of an unexpected power loss, a portion of unqualified data that has not been qualified as written is transferred from the volatile memory to the NVSM.
