D HDD data read failure
The data written to the HDD cannot be read normally.
Bad sectors were generated during operation.
(An error occurred in partition "a" (SC863-02) to partition "v"
(SC863-23)).
Guide for when to replace the HDD
1. When SC863 has occurred ten times or more

The interval is short.

Repeatedly occurs in the same situation (At power-on,
etc.).

Startup takes a long time when the main power is turned
ON.
2. It takes a long time after main power on for the operation
panel to become ready.
HDD access may be consuming time. Normal HDD access
time after main power on is about 5 seconds. If the machine
is not waiting for the engine to be ready and it still takes 20 to
30 seconds or more, the HDD may be the cause. If there is a
problem with the HDD, HDD-related SCs such as SC860
and SC863 will occur frequently. Print the SC log data and
check them.
