CPU/Disk Drive Troubleshooting
A4 Hard Disk Drive
Overview
The A4 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. To restore the C: drive using the image stored in this recovery partition
see the section titled “Hard Drive Recovery Process” on page 159.
C.
This partition contains the operating system and software installed by
Agilent. This is an open system which means you can install additional
software, which should be installed on the C: drive. 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
Agilent Recovery process is ever run, the original version of the C: drive,
as shipped from the factory, will be restored. The user will need to reload
any other software that was previously installed into the instrument.
Do not save any user data to the C: drive partition, as any data saved in
this partition will be lost if the Agilent Recovery process is run.
D.
This partition is reserved for data storage. The User Accounts that are
preconfigured by Agilent and their My Documents folder are mapped to
the D: drive. This is for the convenience of backing-up the user data. You
should always back-up the data on the D: drive. This allows you to restore
the data if the A4 Disk Drive assembly ever needs to be replaced.
Data saved in this partition will not be lost if the Agilent Recovery process
is run.
E.
This partition is reserved for Agilent's use. The primary use of the E: drive
is for storing of the instrument Calibration and Alignment data. Do not
change or overwrite the files on this drive. This could cause your
instrument to not meet specifications, or even to stop functioning
correctly. It is also recommended that you back up the contents of this
drive. 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 Agilent Recovery
process is run, do not use this drive for data storage.
