Auto mount target on Mountain lion

[Jeff48]

I'd like to put my $0.02 in here.

Since SD is not currently auto-mounting the volume (I too want to keep it dismounted when not in active use by SD so as to keep its contents inviolate) I thought I'd get "cute" and use the "Run Shell script before copy starts" option using this script:

#!/bin/sh
diskutil mount "SG SuperDuper! Backup"

The script runs fine when run by itself, but SD does not seem to run it until after its decided that its target volume is not available, causing an error.

Is there any way to get this capability back in one way or another?

MANY thanks for a GREAT product!!

Jeff
