unable to add a second usb-disc as target to Windows backup (server2012)

Hi,

we have a server 2012 Essential and there is running windows backup on it with 1 usb-drive as target. Now we want to add another usb-disc to rotate the targets. If i use the gui, it says after formating the the system cant find the path.
So i used comand-shell (started with admin rights elevated).
wbadmin get discs shows me that the guid of my drive is {111-111-111-111} (e.g)
so i use "wbadmin enable backup -addtarget:{111-111-111-111}"

The system asks if i want to use the disk - i say yes
The system asks me if the disc should be formated - i say yes
The systems tells me that the path couldn´t be found.

After that i look with "wbadmin get discs" after my discs -> the disc now has the guid {222-222-222-222}

It seems that the formating gives the drive a new guid, but wbadmin after that itselfs tries to add the drive with the old guid...
If i don´t accept the formating wbadmin stops the process.

Any idea what to do ?
