*1 The ODD control firmware is stored on the flash ROM and can be downloaded from the host with the WRITE BUFFER command. However, if any problem occurs during downloading, such as power failure, downloading is interrupted and the microcodes in the control firmware may be damaged. To download microcode data again in such a case, the ODD starts the emergency download firmware that simply supports only the WRITE BUFFER command and other basic commands.
