CPU/Disk Drive Troubleshooting
A5 Disk Drive Description
Drive Partitioning
The A5 Disk Drive assembly has been divided up into four different partitions.
They are:
In addition, a hidden recovery partition is located on the drive. This partition
contains an image of the C: drive as it was when the instrument was shipped
from the factory.
C.
This partition contains the operating system and software installed at the factory. This is an open system
which means you can install additional software, which should be installed on the C: partition. However,
only a limited set of software applications are tested for use with the instrument software. The
installation and/or use of other software is not warranted, and could interfere with the operation of the
instrument software. If the Instrument Image Recovery process is ever run, the original version of the C:
partition, as shipped from the factory, will be restored. The user will need to reload any other software
that was previously installed in the instrument.
Do not save any user data to the C: partition, as any data saved in this partition will be lost if the
Instrument Image Recovery process is run.
D.
This partition is reserved for user data storage. The My Documents folders for the user accounts that are
preconfigured from the factory are mapped to the D: partition. This is for the convenience of backing-up
the user data. You should always back-up the data on the D: partition. This allows you to restore the
data if the A5 Disk Drive assembly ever needs to be replaced.
Data saved in this partition will not be lost if the Instrument Image Recovery process is run.
E.
E.This partition is reserved for Keysight's use. The primary use of the E: partition is for storing of the
instrument calibration and alignment data. Do not change or overwrite the files on this partition. This
could cause your instrument to not meet specifications, or even to stop functioning properly. It is
recommended that you back up the calibration database saved on this partition. For information on how
to backup this data see
“Calibration Data Backup and Restore”
. This allows you to restore the data if the A5 Disk Drive assembly ever needs to be
replaced, which could otherwise require that all instrument adjustments be performed.
While data saved in this partition will not be lost if the Instrument Image Recovery process is run, do not
use this drive for user data storage.
