Don't worry about it too much, the relevant files on all disks work. Only the X-Copy Pro 3.1 disk actually had bad files:
l:Aux-Handler, l:Shell-Seg, devs:Mountlist, devs:printer.device
These can probably be taken from any 1.3 wb disk, but the good bits are all there anyway, so why bother.
Let's coordinate the next batch a little better. I'll send you a pm once it's time. :-)
