It works (tested today) under Windows. I have used it with several
linux distros in the past without problems.

Things got even more weird today... Now copying with sync option
enabled don't help at all :(

Besides, another strange problem appeared:
I copy some files to memory stick under FreeBSD
Reboot and read them under Windows (they contain errors, of course...)
Then I copy some files under Windows.
Another reboot into windows - I can see files that were copied under
FreeBSD (with errors) and Windows (no errors).
Reboot into FreeBSD. I mount memory stick ang guess what? I see only
files that were copied under FreeBSD :) Files copied during Windows
session disappeared...
