Abstract: In a storage system, a disk device performs recovery and transfers read data to a control device, and the control device judges the validity of the recovery to prevent a transfer of erroneous data. A control device read-accesses a disk device, and the disk device returns read data and a recovered read error response. A control device, at the time of an initial recovered read error, performs a retry of a similar command, and if an error does not occur for read commands including the retry read command, judges the data to be valid. Uncertain data (suspect data) upon occurrence of a recovered read error is restored through disk retry, and accurate read data can be transferred to the host.

Abstract: A structure in which an electronic part is mounted on a substrate via mount resin and has electrodes thereof connected to electrodes arranged on the substrate for wire bonding by conductors is disclosed. A frame for preventing the mount resin from flowing out is formed on the substrate between a portion for mounting the electronic part and the electrodes for wire bonding. The structure prevents the mount resin from flowing out with a relatively simple scheme at low cost, and allows the number of semiconductor chips or similar electronic parts to be increased in order to implement high-density buildup wiring.
