<P>PROBLEM TO BE SOLVED: To prevent information leakage from a disk drive removed from a disk array system simply at a low cost. <P>SOLUTION: The disk array system is provided with a memory for storing a first key data unique to the disk array system and a disk controller for controlling input/output of data to/from the disk drive. The disk drive is provided with a disk medium having a system area storing a second key data unique to either of disk array systems and a data area storing user data, and an HDD controller for controlling the data input/output to/from the system area and the data area. The HDD controller compares, when the disk drive is loaded to the disk array system, the first key data with the second key data. If they do not match, an operation mode is executed which inhibits read access from the disk controller to the data area. <P>COPYRIGHT: (C)2007,JPO&INPIT |
