You cannot convert .mds file (Alcohol 120% disk image descriptors) to MagicISO format (.uif). For a successful mds to uif conversion, you would also need a corresponding .mdf file that actually contains the disk image which is needed for the conversion. This means that a lone .mds file is somewhat useless to you for conversion purposes.
