Subject: *COPY Disc Corruption
I have tried everyone's suggestions and I haven't really got to the
bottom of what has happened, although I did find a solution.
I manually LOADed and SAVEd the three files from the 5.25" drive
to the 3.5" drive, but this died on the third file, giving me disc error
18 again. The only thing I could possibly think of is that there might
be some timing problem with the drive when writing something on track 0
and then going back to sector 0 to update the catalogue (or the other
way round, whichever way DFS does it).
If I saved a larger file first on a blank disc, taking up more than the
first track, then *COPY worked fine for the three files I was copying.
I then deleted the big file and compacted the disc and it was fine.
All I was trying to do was copy of few bits onto a 3.5" disc so I could
make a disc image to e-mail to somebody, and it turned out to be
very troublesome!
Best wishes,
Ian

What happens if you write to a disc in :1 in other ways? Does that
corrupt the catalogue too, or is it just *copy?
