1-1 The machine will not permit the use of
service mode; go through the following:
1-2 Turn off the power. Then, turn on the power
while holding down on the 1 and 9 keys so that
the repair routine for the sector for which the
write operation was suspended will
automatically start up and the screen will turn
solid black.
1-3 Wait for about 40 to 50 min. There will soon
be an indicator of progress of work. The screen
will turn solid white when the routine ends.
<if the spanner symbol is indicated>
1-1 Set 'CHK-TYPE-0', and execute 'HD-
CHECK' (50 to 50 min); thereafter, turn off and
then back on the main power switch.

start up in safe mode; then, format the HDD (full)
using the SST, and re-install the system software
(System, Language, RUI), and turn off and then
back on the main power switch.
3. If the symptom still exists after the foregoing,
suspect a fault on the HDD, and replace the HDD
and re-install the system software.
