The other partition 'at fault' is a WinXP-style NTFS filesystem, formatted during the WinXP SP1 installation some time ago. So far, I've only seen the problem in WinXP's special 'My Pictures' directory. >Description: 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 ;) >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.
