+This command runs the L<ntfs-3g.probe(8)> command which probes
+an NTFS C<device> for mountability. (Not all NTFS volumes can

+if the volume can be mounted read-write. Set it to false if
+you want to test if the volume can be mounted read-only.

+The return value is an integer which C<0> if the operation
+would succeed, or some non-zero value documented in the
+L<ntfs-3g.probe(8)> manual page.
