A5 Disk Drive
The standard A5 disk drive is a solid state (FLASH) drive. There may be
different drive capacities being used, and due to continual changes being
made by the drive manufacturers these will continue to change from time to
time.
Failures of this disk drive can be either hardware or software related. The first
step in troubleshooting is to determine if the failure is software related. If
software is found not to be the issue, the disk drive should be replaced.
Before replacing the A5 disk drive it is highly recommended that the factory calibration data be
backed up to an external drive if at all possible. If this data is not backed up prior to replacing
the disk drive all instrument adjustments and performance verification tests will need to be run
after the drive is replaced.
For information on how to backup this data see “Calibration Data Backup and Restore”
on page 647.
