Abstract
A disk drive comprising a rotatable disk, a head actuated over the disk, and a controller is disclosed. The controller is configured to write data on the disk using the head, to store logical-to-physical mapping information for data already written on the disk in a circular buffer as the data is written on the disk, and to write a plurality of metadata files on the disk using the head, wherein the plurality of metadata files are interspersed with the data on the disk and each of the metadata files includes contents of the circular buffer at a time the metadata file is written on the disk.
