Perhaps the Cygwin DLL is trying to identify the Cygwin root directory
as one higher than its own location so that it can locate /etc/fstab
etc. If it's in the root of a drive maybe it's getting confused. Create
an x:\bin\ directory (where x is the drive letter of the UDF device)
into which to place cygwin1.dll and the executable.
