I think the problem comes earlier: the (let ((default-file-modes ?\700))
should make sure that the directory created there is owned by the use
and not by some Administator group.

Of course, on FAT there's just nothing we can do and the
server-ensure-safe-dir functionality simply cannot be provided, so we
should then just skip the safety checks,
