Disk Drive Troubleshooting
This will format the entire disk drive, both the partition used for the firmware
application software and the user stored data files. Because of this, once the
formatting is complete the instrument firmware will need to be reloaded, and
all user files will be lost.
1. See “Boot Service Menu” in Chapter 5, “Service and Utility Menus,” for
instructions on how to access the menu.
2. Once in the Boot Service Menu highlight Format SSD and press Select.
3. The drive will be completely formatted.
4. After the format completes, highlight Reboot and press Select to restart
the instrument.
When the instrument is restarted after the disk drive is formatted the following
errors may be seen:
— 315, Configuration memory lost; Persistent state checksum is bad. Using
factory defaults.
— 256, File name not found; /USER/USERFLAT/LAST
— 256, File name not found; /USER/PTRAIN/LAST
The instrument will correct these errors after the power is cycled again.
However, the instrument will not be able to recover from the following error by
itself:
— 310, System error; Failed to start Application or CalTest harness
To recover from this error the instrument firmware will need to be reinstalled.
See Chapter 19, “Instrument Firmware and Operating System,” for information
on how to reinstall the instrument firmware.
If after formatting the disk drive the original problem persists, replace the A4
Solid State Disk Drive.
The Format SSD function will not ask for a confirmation of formatting once
selected. Be sure this is the desired function before selecting it.
