Abstract:
A data process can be performed without lowering the data processing efficiency even when the sector length of the host device side is different from the sector length of the hard disk side. Partial data or whole data of a second data block which is based on a long sector defined on the hard disk side and surrounds the starting end and terminating end addresses of a first data block based on a host-defined sector is read from the hard disk and written to a flash memory before the data process using the flash memory as a cache is performed based on the command.
