I don't fully understand what your problem is
Welcome baz136
Yeah I tried to help with this before there were any replies, but couldn't figure out what you were actually asking. Eventually I gave up concluding that one of us must be under the alfluence of incohol :lol:
If I now get the gist of it, you are booting into an A1200 with Workbench 2.05 and trying to use PC0. You could also try putting 'fat95' into the L drawer of your Workbench floppy and double clicking on MS0 to read PC formatted floppy disks.

This avoids all the jumbled up file names and under Workbench OS3.9 you actually get an icon for the floppy disk with a Windows logo on it :-)
