摘要： A hard disk drive (HDD) minimizes the effects of far track erasure (FTE) by counting the number of writes to the data tracks and incrementing counters based on the known effect of FTE on each track. The extent of the FTE effect is determined for each track within a range of tracks of the track being written, and based on the relative FTE effect for all the tracks in the range a count increment (CI) is determined for each track within the range. A counter is maintained for each track. For every writing to a track, a count for each track within a range of the track being written is increased by the CI value associated with the track number within the range. When the count value for a track reaches a predetermined threshold the data is read from that track and rewritten, preferably to the same track.

摘要： 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.

摘要： A data storage device has a data storage medium. A data storage capacity of the data storage device is divided into slices. Each slice has a set of sectors. Data storage device firmware is configured to store copies of a system image in the slices on the data storage device. Each of the slices stores a different copy of the system image.
