Abstract:
1. A storage apparatus comprising: an I/O controller configured to receive an access request sent from an information apparatus communicatively coupled thereto and write data to or read data from a storage drive in response to the access request; a storage drive mounting unit, in which the storage drive is detachably mounted, capable of mounting therein a plurality of types of the storage drives with a same drive voltage and accessible in accordance with different access methods and allowing different numbers of times of data write; a drive power supplying unit configured to supply drive power to the storage drive mounted in the storage drive mounting unit; and a drive voltage identifying unit configured to be capable of identifying a voltage allowing data write to or data read from the storage drive by raising a drive voltage applied to the storage drive mounted in the storage drive mounting unit from a voltage not higher than a rated drive voltage of the storage drive; checking whether data is writable to or readable from the storage drive in accordance with an access method of the storage drive; and checking whether data is writable to or readable from the storage drive while applying the access methods of the storage drives in ascending order of the allowed number of times of data write, wherein when the I/O controller writes data to or reads data from the storage drive, the drive power supplying unit is configured to apply the identified voltage to the storage drive to drive the storage drive.
