    • For limiting data loss due to ATI or ATE, an apparatus may include a storage module, a tracking module, and a refresh module. The storage module is configured to store a risk value for a tracked storage division. The risk value indicates a risk level of data loss for the tracked storage division. The tracked storage division is one of a plurality of storage divisions of a data storage device. The tracking module is configured to update the risk value to indicate a higher risk level based on a write to a physically proximal storage division. The physically proximal storage division is within an interference range of the tracked storage division. The tracking module is configured to reset the risk value based on a write to the tracked storage division. The refresh module is configured to refresh the tracked storage division based on the risk value meeting a threshold value.
    • 为了限制由于ATI或ATE引起的数据丢失,设备可以包括存储模块,跟踪模块和刷新模块。 存储模块被配置为存储跟踪的存储分区的风险值。 风险值表示跟踪的存储部门的数据丢失的风险级别。 跟踪存储部是数据存储装置的多个存储部之一。 跟踪模块被配置为基于对物理近端存储分区的写入来更新风险值以指示较高的风险水平。 身体近端存储部门在跟踪的存储部门的干扰范围内。 跟踪模块被配置为基于对跟踪的存储分区的写入来重置风险值。 刷新模块被配置为基于满足阈值的风险值来刷新所跟踪的存储部门。
