A data transfer control device includes an ATA device-side I/F, an ATA host-side I/F, a transfer controller, and a processing section which performs emulation processing. The processing section performs the emulation processing including, when the device-side I/F has received a command from an ATA host, issuing a command corresponding to the received command to a ATA device, starting data transfer through a bus ATABUS1, the device-side I/F, the host-side I/F, and a bus ATABUS2 after issuing the command, and, when the host-side I/F has read a status from the ATA device after completion of the data transfer, returning a status corresponding to the read status to the ATA host.
