I wrote the file made_in_win.txt and made_in_linux.txt before resuming windows.
I did not try writing something after resuming XP. I did look at the
two files after
XP resumed and they looked fine. I'm not saying everything is safe as
I have done only
this one test. Does this answer your question?

Thanks.
I'll take a look at this possibility. Actually, for me I almost never
write the same files
to the fat partition or share data between XP and Linux. I only use
Windows (actually
my wife does) for video chatting and thing like that. And I thought it
is very convenient
for many other people who dual-boot to have this option if it can work safely.

 Best,
