Abstract
A data storage device has a data storage medium configured to store a first version of data in parent sectors. The data storage device is configured to store a second version of the data in child sectors. The child sectors have the same logical block addresses as the parent sectors. A host operating system can read data from or write data to the child sectors by sending logical block addresses and a sector set number to the data storage device. The logical block addresses and the sector set number identify the child sectors. In response to receiving a request to access the child sectors, the data storage firmware identifies physical addresses that correspond to the logical block addresses and the sector set number. The data storage device uses the physical addresses to identify the location of the child sectors.
