Yes, first I tried 8, then 0x8000, then 0xFFFF and finally I've come to 0x0001. The last is the one I use currently cause it disables the Dialog (0xFFFF does too). I dont know if there is any other possibility (Mode) to do this, but a dialog poping up three times for each file tested with -e on a path that points to a empty CD-Rom is really annoying.
