Either of the windows as shown below is displayed. The message "[C drive is ....]" displayed at the top of the screen shows the EWF state at the moment.
[Protected] means that the EWF function is enabled, but writing to a CF card is disabled.
[not Protected] means that the EWF function is disabled, but writing to a CF card is enabled.

|
| Important |
| After performing a certain process, return the status back to the "EWF Enable" (or "Protect ON") with the same procedure. It makes writing to a CF card disabled afresh so that unexpected data update or deletion cannot be performed. In the Windows XP Embedded environment, the "EWF Enable" (or "Protect ON") is recommended for usual operation. |
