Under File Encryption, click the drop-down button of the
Ignored Devices field.
In the editor list box:

Enter the required device names to exclude specific devices from

SafeGuard Enterprise logs all devices it connects to and you can
display a list of attached and ignored devices by using registry
keys. For further information, see Displaying ignored and attached devices on Windows.
You can exclude individual (network) disk drives from encryption by creating a
File Encryption rule in a File Encryption policy and set
the encryption Mode to Ignore. You
can apply this setting only to Windows administered drives and not to Mac OS X
