Technical Examples
- A disk array system having first and second housings and a controller for controlling the first and second housings. Fiber channel hard disk drives are received in the first housing, and serial ATA hard disk drives are received in the second housing. When reading data stored in a serial ATA hard disk drive in the second housing, the controller reads a plurality of pieces of data including the data to be read and parity data for the plurality of pieces of data from all the hard disk drives of an RAID group to which the hard disk drive storing the data to be read belongs. Thus, the controller examines whether the plurality of pieces of data including the data to be read are written in the hard disk drives with erroneous contents or not.

- A security structure of portable hard disk drive is disclosed to include a bracket fixedly mounted in a computer case, a plurality of portable hard disk drives inserted into respective sliding grooves inside the bracket at different elevations, and a locking rod, for example, a long screw for insertiing through a through hole on the top panel of the bracket and a respective through hole on each portable hard disk drive and threading into a nut at the bottom panel of the bracket to affix the portable hard disk drives to the bracket. The locking rod is kept from sight after installation of the portable hard disk drives in the bracket and closing of the computer case.
