Yes, I stopped using Petrov DOSFS very much because the slightest
touch by a Windows machine screwed up addresses. It's useful for
doing quick&dirty copying to&from DOS disks. Nowadays I tend to put
the DOS disks in the A5000 and drop eveything over to the server
from there.
Even with RISC OS, if Pretov DOS FS stores a load address of
&FFFBBC00, which is filetyped to &BBC, RISC OS doesn't see it. It
only sees the filetype if DOS FS has stored &000BBC00, which is a
bit pants.
I tend to zip things on the Beeb before putting the zip archive on
a DOS disk nowadays to keep all the metadata.
