The Keysight Recovery System is stored in a separate hidden harddisk drive partition.Repairing errors on the hard disk drive may result in loss of data or files. If youneed more information about the Windows “chkdsk” error repair process, seethe chkdsk documentation in the Microsoft Windows Help and Support Center.Restoring the original factory system software does not restore any of thefollowing items:— Windows system configurations that were made after the instrument wasshipped from the factory. For example, Windows and Service Pack updates,user accounts, and windows configuration settings. After an KeysightRecovery, these configurations need to be redone.— Additional software that was installed after the instrument was shippedfrom the factory. After an Keysight Recovery, that software needs to bere-installed.— Any data or programs saved on the D: or E: drives.— Any upgrades that were made to the Keysight measurement applicationsoftware.Restoring the original factory system software will not synchronize the code inthe Field Programmable Gate Arrays (FPGAs) on the various hardwareassemblies. As a result, you may see an error dialog box appear during the finalboot-up at the end of the recovery process. This typically occurs when thereare significant differences between the software version installed prior toperforming the recovery and the version restored by the recovery. In thesesituations, upgrade the software to the latest version.Calibration data is not lost during this process because it resides on the E drivepartition.
