Claim 13:
14. A data storage device, comprising:
a memory device storing a first copy of a boot partition and a second copy of the boot partition, wherein the first copy and the second copy comprises a same number of boot chunks, wherein a first boot chunk of the second copy corresponds to first data of a first boot chunk of the first copy, and wherein the boot partition corresponds to second data associated with a boot operation of a host device; and
a controller coupled to the memory device, wherein the controller is configured to:
maintain a delta table, wherein the delta table tracks which boot chunk of the first copy matches a corresponding boot chunk of the second copy and which boot chunk of the first copy is different than a corresponding boot chunk of the second copy;
determine that the boot operation is occurring; and
utilize the first copy, the second copy, and the delta table in a decoding operation to provide the boot partition to the host device.
