Starting the download only firmware (*1)
A power-on diagnostics error occurred.
A thermal alarm occurred.
An error occurred during writing to the WRITE cache (*2)
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.
The blinking of the LED for the error during writing to the WRITE cache is
cancelled by ejecting the media.
