Disk Drive Recovery Process
Disk Drive Recovery Process
The Instrument Image Recovery System can be used to repair software errors 
on the instrument's disk drive, or to restore the original factory configuration of 
the system software. The Instrument Image Recovery System is stored in a 
separate hidden disk drive partition. Repairing errors on the disk drive may 
result in loss of data or files. Restoring the original factory system software 
does not restore any of the following items:
— Windows system configurations that were made after the instrument was 
shipped from the factory. For example, Windows and Service Pack updates, 
user accounts, and windows configuration settings. After a recovery, these 
configurations will have to be redone by the end user.
— Additional software that was installed after the instrument was shipped 
from the factory. After a recovery, that software will need to be re-installed 
by the end user.
— Any data or programs saved on the D: or E: drives. This data will be retained 
on the drive and not altered by the recovery process.
— Any updates that were made to the Keysight measurement application 
software.
Calibration data is not lost during this process because it resides on the E drive 
partition.
