Abstract
Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator mechanism configured to position heads proximate to a recording medium of the disks; and one or more processing devices. The processing devices are configured to detect a criterion for inserting padding on the recording medium proximate to data containers to be written to the recording medium, the containers configured for assigning logic blocks to the containers, the logic blocks configured to store data to be written in an interleaved pattern across sectors based on a distributed sector encoding scheme, wherein detecting the criterion comprises detecting a mismatch in size between at least a portion of a zone and an integer number of containers in which to write the at least a portion of the zone; and insert mapping indicators to a mapping to indicate padding blocks proximate to the containers.
