Just a thought, but in normal circumstances files *are* written to, even when they are just being read: the access time is updated (unless you mount the fs with the noatime flag). quite true, but isn't that file metadata and not the actual file? I thought most filesystems had a file-entry

Ans set 'hw.ata.wc=0' in /boot/loader.conf to stop the drives from caching writes. it will GREATLY reduce write performance. not just a bit, but many times. WRT softupdates/gjournal, see below. In case of frequent power outages, I guess the right answer is get a UPS. :) it is definitely

If the files themselves are disappearing, then it could be the directory entry that's getting corrupted. The files are there, but their content is corrupted. Even if you're not doing it directly, is your mp3 software writing temp or other status files to that directory? If you're curious,
