Sometimes then I transfer files between my Canon PowerShot digital
camera and WinXP (gphoto mostly works, but there are unrelated reasons
for using WinXP some of the time).  Microsoft's Scanner and Camera
Wizard tranfers the pictures and places them into a folder of my choice,
usually within My Documents/My Pictures.

So far the problem has only appeared once, but it had me stumped for a
couple of hours: I had transferred a set of 6 pictures, then, a couple
of days later, tried to access them from FreeBSD, and could not find
them in the directory where I could swear I'd put them before. An 'ls'
on that directory comes up with, well, nothing - no files, no subdirs,
no nothing (well, '.' and '..' are there alright).  The funny part is,
the directory seems to contain DOS-style 8.3 names only, and no NTFS
(type 2) names at all!  A couple of debugging printf's in ntfs_vnops.c
revealed that ntfs_readdir() never sees the directory because
ntfs_ntreaddir() never finds it; it's not a matter of
ntfs_nameispermitted() returning false, as seen from the mount -a case
below.

Since I know nothing about NTFS's directory organization, that's the
point where I give up.  Please tell me what other information you need,
and I'll provide it - well, short of the full 15GB raw partition dump,
since that would be a bit unwieldy to keep in GNATS, besides other
reasons ;)

Fix: 

Hopefully one can be found before 5.3 ships :)  Not critical in any way,
though.
How-To-Repeat: 
No, I'm not saying you can repeat that by executing the below commands;
still, that's what they do for me.  The 'My Pictures' directory is fine,
but its subdir 'mrs sarbenishka 20040910' contains six files that WinXP
can see just fine, yet FreeBSD's ntfs.ko cannot.  Further down, mounting
with NTFS_MFLAG_ALLNAMES shows six DOS-style names and that's all.
