Obviously, an NTFS-based machine would be great, but they aren't playing nice, and I'm afraid my Winfoo isn't up to snuff (and I was up most of the night with it, so my RTFM is suffering, too) FreeBSD mounts and reads both partitions on the drive, but when I attempt to read the large file, every operation seems to truncate the file at about 2 GB. Since I've tried cp(1), dd(1), tar(1), cpio(1), FTP, and SMBFS, (plus Freesbie, Knoppix, and NTFS for Win98) I'm starting to think that it's the underlying FreeBSD NTFS layer that's at issue (in the FreeBSD portions of the problem, I mean). Can anyone confirm my hunch? I think there are PRs about this. I don't find many, but, I've not spent too much time on the search page. Most applicable one I see was from 2004, about 5.2 days. I would assume that any changes would reflect in 6.0. Of course, if I really *wanted* to know, I could check the cvsweb, eh? And, even better, have you got a surefire way to get "my_very_important.bkf" off the disk? ;) /usr/ports/sysutils/ntfsprogs/ ? Kris Thank you very much for your reply. I'm hopeful that this will help!

Where can I send $beverage? For the archives: 1. Install port mentioned above. 2. ntfscat -fv /dev/ad3s2 important.bkf > /usr/recovered.bkf 3. restore as per Windows SOP. So, "ntfscat" is able to handle large file operations (>2GB) in FreeBSD, operations that seem to fail with mount_ntfs and standard 'Nix tools (cat, cp, cpio, tar, dd, etc). Important: I've not yet verified that the disk is still readable by Windows, but since the data's off, I'm not sure I care, and Windows wasn't seeing it properly anyway. A reformat should do the trick. YMMV.
