- HD-CLEAR
When you have executed HD-CLEAR, all contents of the partition in question (files, sub directories) will be lost.
The actual formatting will take place when the machine is started up after it has been turned off upon execution of
HD-CLEAN.
At this time, the Startup screen shows a progress bar, its edge reaching the end in about 5 min. Be sure not to turn
off the power while the progress bar is moving.
This function (i.e., mode item) cannot be used for BOOTDEV and DOSDEV4; to re-format any of these 2 partitions,
you will have to use the SST.
Keep in mind that formatting of the HDD in service mode will necessarily be full formatting.
- HD-CHECK
If the power is cut while data is being written to the HDD, the occurrence of a write-suspended sector is a possibility.
YY Description
13, 25 The ongoing write operation
has been suspended.
10, 12, 14, There is a system error or a
22, 23, 24 packet data error.
Remedy
There is a likelihood of the presence of
damage to the file data on the HDD (e.g.,
Box).
1. Set '0' for TYPE-TYPE, and execute
HDD-CHECK (40 to 50 min). Thereafter,
turn off and then back on the power.
2. If the symptom still exits after the
foregoing, set '1' for TYPE-TYPE, and
execute HDD-CLEAR.
(In the case of DOSDEV4 or BOOTDEV,
execute formatting and re-installation once
again.)
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.
The data may be corrupted or there is a
software bug.
1. Start up in safe mode, and execute full
formatting using the SST and re-install the
system software (System, Language,
RUI). Thereafter, turn off and then back on
the main power.
2. If the symptom still exits after the
foregoing, suspect a fault on the HDD, and
replace the HDD and re-install the system
software.
