A4 Hard Disk Drive
A4 Hard Disk Drive
The CXA A4 Hard Disk Drive is physically connected to the CPU assembly.
Failures of this disk drive can be either hardware or software related. The first step
in trouble shooting is to determine if the failure is software related. If software is
found not to be the issue, the hard disk drive should be replaced.
IMPORTANT Calibration File Backup
Backing up the calibration file before changing the A4 Disk Drive is highly
recommended. To do this you will need to connect a USB mouse and follow the
steps below:
a. Right click on the Start Menu.
b. Left click “Explore”.
c. Navigate to the E:\ drive (Calibration E:).
d. Click on the E:\ drive.
e. Double click on the AlignDataStorage folder.
f. Save the CurrentDataSet.xml file onto a USB storage device.
Once the new A4 Disk Drive is installed, copy the Current DataSet.xml file from
the USB storage device to the AlignDataStorage folder on the E:\ drive
If this file cannot be backed up because the instrument will not fully boot, go ahead
and change the A4 Disk Drive and perform all adjustments listed in Chapter 14 ,
“Post-Repair Procedures” for the A4 assembly.
