Abstract
Managing data stored in a Data Storage Device (DSD) including a volatile memory and a non-volatile memory including a circular buffer. Metadata stored in the volatile memory is logically divided into blocks of metadata. At least one changed block of metadata is identified that has changed during operation of the DSD and the at least one changed block of metadata is stored in the circular buffer of the non-volatile memory.
