Drive Removal and Replacement
1. 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 the “Calibration Data
Backup and Restore” section in Chapter 15, “Post-Repair Procedures.” of
this manual.
If this data cannot be backed up because the instrument will not fully
boot, go ahead and change the A5 Disk Drive and perform all adjustments
listed in Chapter 15, “Post-Repair Procedures.” for the A5 assembly.
2. Turn the instrument off and remove the AC power cord.
