The problem is definitely with VCC.  If you pad out the Urbane.dsk
file to exactly 161,280 bytes (630 sectors) VCC will still not be able
to access it properly.  I think it is seeing the data in track 0
sector 1 and deciding that it must be an OS-9 disk (even though it
isn't). It then uses that information to setup an incorrect disk
geometry.
