I mounted an ISO file on `D:`. Command line execution of `df` in Cygwin:

$ df D:\\
Filesystem     1K-blocks   Used Available Use% Mounted on
D:                329600 329600         0 100% /cygdrive/d

Output from the test:

C:\ (508674699264):
  getSpace0 total = 322122547200 free = 339768209408 usable = 259194875904
  getXSpace total = 322122547200 free = 339768205312 usable = 259194875904

D:\ (0):
  getCDDriveSpace total =            0 free =            0 usable =            0
  getXSpace total =    337510400 free =            0 usable =            0


FAILED: 'D:\ total space': 337510400 > 0
FAILED: 'D:\ size': 337510400 > 0
24 tests: 2 failure(s); first: java.lang.RuntimeException: 'D:\ total space': 337510400 > 0
java.lang.RuntimeException: 1 test(s) failed
        at GetXSpace.main(GetXSpace.java:400)

So I don't see any difference between a physical drive and a mounted ISO file with respect to this test.
