It is interesting that both of these cases relate to MP3s. I have also seen a case where MP3 files and their parent directories disappear, but they are not gone. What happens for me is that there is a problem with UTF8 character set mapping and NTFS-3g treatment of names with these extended characters. when this happens I see messages like this in /var/log/daemon.log: Apr 9 21:35:41 alohomora ntfs-3g[3487]: Skipping unrepresentable filename (inode 5941)
For example, I do this: [~]% ls /media/sda7/music/listened/Keith\ Jarrett total 0 [~]% killall mpd [~]% sudo umount /media/sda7 Password: [~]% sudo mount /media/sda7 [~]% ls /media/sda7/music/listened/Keith\ Jarrett total 4 drwxrwx--- 1 4096 2005-07-06 20:02 The Köln Concert/ The culprit is the umlaut in Cologne. In my case, running Ubuntu, I think there is some startup problem with the NLS system in which NTFS-3g starts and mounts the filesystem too early. Hence, umount/mount gets it working again. If the directories you are missing make use of extended characters, this could explain the problem.
