Chapter 15
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. When HD-CHECK is run on such a sector, repairs will be
made, but all data in the sector will be lost. A write-suspended sector may be repaired only
by HDD-CHECK (0); if not TYPE-TYPE=0, the task will be limited to an FS level check.
If the write-suspended sector happens to be a critical sector that holds a control area, there
is no way of repairing it; you will have to execute HDD formatting.
- Replacing the HDD
1. Turn off the main switch.
2. Connect the new HDD.
3. Start up the machine in safe mode.
4. Connect the SST, and execute full formatting.
5. Using the SST, download the system software (System, Language, RUI).
6. Turn off and then back on the power. (It may take about 5 min for the machine to start up).
