Hmm.. perhaps I have gained from not using the editors to do anything except
calculate checksums then. The data part is certainly different - it appears to
be just contiguous data - but I have successfully edited a ffs volume several
times working from guesses and the 1.1 AmigaDOS manual, so don't despair.
Perhaps you need as simple minded a program as possible, eg disked.
Stay clear of the files, and just change directories, and you may be ok.
Of course, it all depends on whether validation fails in a well defined place..
Still.. good luck.
