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.
摘要翻译：硬盘驱动器（HDD）通过根据每个轨道上已知的FTE效应计数对数据磁道的写入次数和递增计数器，从而最大限度地减少了远跟踪擦除（FTE）的影响。针对正在写入的磁道的磁道的范围内的每个磁道确定FTE效应的范围，并且基于对该范围内的所有磁道的相对FTE效应，对该范围内的每个磁道确定计数增量（CI）。为每个轨道维护计数器。对于对轨道的每次写入，在被写入的轨道的范围内的每个轨道的计数增加与该范围内的轨道号相关联的CI值。当轨道的计数值达到预定阈值时，从该磁道读取数据并将其重写，优选地改写为相同的轨道。

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.
摘要翻译：数据存储设备具有数据存储介质，其被配置为在母扇区中存储第一版本的数据。数据存储设备被配置为在子扇区中存储数据的第二版本。子扇区具有与父扇区相同的逻辑块地址。主机操作系统可以通过向数据存储设备发送逻辑块地址和扇区集号，来读取数据或向子扇区写入数据。逻辑块地址和扇区集号确定子扇区。响应于接收到访问子扇区的请求，数据存储固件标识对应于逻辑块地址和扇区集号的物理地址。数据存储设备使用物理地址来识别子扇区的位置。

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.
