Getting Started Guide 151Test Set Operating SystemHard Drive Recovery ProcessHard Drive Recovery ProcessThe Keysight Recovery System can be used to repair errors on the test set's C:drive partition, or to restore the original factory configuration of the systemsoftware. 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 test set 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 test set was shipped fromthe 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.It is recommended that routine backups of the test set information beperformed to keep current archives of the test set information. This allows a fullrecovery of the test set information after the test set recovery systemoperations are performed. See “Backup” on page 147 for more details.It is recommended that you use a regular back up strategy. Your IT departmentmay already have a back up strategy in place which is suitable for the test set andits data. See “System Maintenance” on page 147. Using the KeysightRecovery System in conjunction with a regular back up strategy should allow youto fully recover the test set software and data.
