… the file copied to the ntfs disk is missing. …
A: On the writing FreeBSD side, make sure the file system was properly unmounted. Until it is unmounted, changes to the file system can be held in memory. On the reading Windows side, make sure the file system was completely re-mounted and all caches cleared. Personally, I would do a full shutdown of FreeBSD, followed by a cold boot (not restart from hibernation or sleep) of Windows.I'm testing with ntfs-3g and when I copy or move a file to disk when restarting, no changes are saved. That is, the file copied to the ntfs disk is missing.
Command: sudo ntfs-3g \dev\ada3s1 \mnt\ntfs
