On the right side you see the EWF Control commands, each with a help button aside
(the commands which are not available in the current constellation are greyed and di-
sabled):
• Enable: Enables a currently disabled overlay on the specified EWF-protected volu -
me. This function requires a reboot.
• Disable: Disables a currently enabled overlay on the specified EWF-protected volu -
me. This function requires a reboot.
This function is not available at all for the volume C:\ which holds the registry,
because the change in the registry for the new state of EWF cannot become
persistent. Use “CommitDisable live ” instead to disable EWF for C:\.
• Commit: Commits all current level data in the overlay to the EWF-protected volume.
This function requires a reboot. After the reboot the EWF status of the volume is still
“ENABLED”.
NOTICE
All changes on the volume since the last reboot become effective. Do not
execute this if you are not sure about the extent of the changes.
• CommitDisable live: Immediately commits all current level data to the EWF-protec-
ted volume and then disabled EWF. This function does NOT require a reboot.
NOTICE
• All changes on the volume since the last reboot become effective. Do
not execute this if you are not sure about the extent of the changes.
• The changes become effective immediately with reboot and thus
without the possibility to undo this command by “Clear Command”.
• Clear Command:
Clears a pending command for the volume that would have oc-
curred on the next restart.
5.7 Dependent Volumes
As mentioned other volumes than C:\ (typically and in the following E:\ which is the
CFast on KEB devices) are dependent from C:\ to change their configuration, because it
is stored in registry which resides on C:\ and thus registry is also protected against any
change if the EWF is enabled for C:\.
If EWF is disabled for C:\ all commands for the dependent volumes can be used inde-
pendently.
Otherwise, if EWF for C:\ is enabled , the following rules are effective:
• Enable and Disable: If one of these commands is used the following message box
asks if the Commit command for C:\ should also be set. It is recommended to con-
firm with “Yes” because otherwise the Enable or Disable has no effect. The message
will not appear if the Boot Command for C:\ “Commit” already.
