The problem seems to be filesystems with 16k cluster sizes (>1028Mb).
If you're encountering this problem, you'll see an error about cluster
sizes when you mount the partition. Umount it immediately or risk
trashing the whole system.
The only time I've seen something similar to what you're
describing is using the shareware XFS software (NFS server
for MSDOS). FreeBSDs NFS implementation would do very strange
things - I think it was something to do with the size of the
file type attribute being returned to the FreeBSD box. When
you did an "ls" of the top level NFS directory, you'd get a
recursive listing, but "find" would just show you the top
level directory (unless things got buffered, then they got
better).
I'd suggest doing a dos SCANDISK.EXE on the dos filesystem
in question and making sure that it's cluster size is <= 8k.
