Michael Foot's image writing utility worked fine and so my problem is
solved - thanks everyone.

This explains a lot - my disc had never been used before and so it
appeared to work first time I tried it. However, not being sure which
file to run I tried Welcome80. This said something about converting to
80 track format and then hung up. Since then the disc has not worked and
reports "Disk fault 50". I guess there was an error on the 80 track
side.
