By including the EWF Manager console component in your configuration and building it into your image, you enable use of the EWF command line control utility and the corresponding commands. To use the Enhanced Write Filter command line control utility: 1. Select Start > Run. 2. Type CMD in the Open field to access the system DOS prompt. 3. Click OK. 4. Type ewfmgr c: 5. Press enter. When you enter the ewfmgr -[boot command] syntax, use the following commands in the boot command variable of the command line: ● -all Displays information about all protected volumes and performs a command, such as disable, enable, and commit, on each volume, if specified. ● -commit Commits all current level data in the overlay to the protected volume, and resets the current overlay value to 1. You can combine -commit with the -disable command to commit and then disable. ● -disable Disables the overlay on the specified protected volume. ● -enable Enables the Enhanced Write Filter so that data written to the protected media is cached in the overlays. The current overlay level becomes 1 as soon as EWF is started, and a new overlay is created at level 1. ● -commitanddisable Commits data in the overlay upon shutdown and disables EWF after the system reboots. ● -description Use with -setlevel or -checkpoint to add a description for the overlay level that is being stopped. ● -gauge Displays a percent full gauge for the EWF volume. "X" is a number from 1 to 100 and indicates the gauge stepping value. (The default stepping value is 1.) 10 Chapter 2 Enhanced Write Filter (EWF)
