$ rm ~/tmp/foo.img
$ ~/src/_readonly/mtools/mtools-4.0.30/mformat -C -T 4800 -h 2 -s 30 -H 
1710948352 -i "~/tmp/foo.img|data_map=1s,zero31s,28s,skip1s" ::
$ ~/src/_readonly/mtools/mtools-4.0.30/mcopy -i

$ ~/src/_readonly/mtools/mtools-4.0.30/mcopy -i 
~/tmp/foo.img\|data_map=1s,zero31s,28s,skip1s * ::
Cannot initialize '::'
