  • Data storage device and data erase method
    Publication number: 20080112072
    Abstract: A data storage device with a recording medium for which a data erase function unit is introduced to achieve both partial non-erasure of data for analyzing a cause of data error and full erasure of data for protection of personal information. This data erase function unit sequentially performs automatic erasure of data on a hard disk in units of sectors (SC) by turning on a jumper switch, but skips the automatic erasure for any error sector including error among the sectors (SC). For this purpose, it is provided with both an erase unit for full erasure of data and a skip control unit for a partial non-erasure of data.
