Or as I'd seen in earlier documentation, "mount -t ntfs-3g ..." would now work. If that's the way it's supposed to work, it doesn't! I did publish the runes on freebsd-questions when I'd figured them out. When you say mount_ntfs was in older versions, technically correct but with due respect to your accuracy, still not perticularly helpful. It turned up in 1999 with 3.4, I believe, and disappeared without warning (to users) a couple of weeks ago. The first I knew of it was when I needed to mount an external USB drive in a hurry, and got "Command not found". Okay. mount -t ntfs /dev/da0 /mnt/ntfs mount: /dev/da0: Operation not supported by device Build and install fuse stuff, and try again with ntfs-3g as mount's FS and the same unhelpful message appears. Not the best example of user-friendly design I've ever seen (although IBM's "An error occurred during the physical insertion stage" still beats it on style). The current handbook still says (vaguely) that NTFS is available (20.1). Putting something in 4.7.2 that's useful in this respect (i.e. -t options in mount can be one of.... and if you want to mount NTFS, he's how) would be a good start. I suspect mount_fusefs has something to do with the new solution, but to quote its current man page: DESCRIPTION Basic usage is to start a fuse daemon on the given special file. In practice, the daemon is assigned a special file automatically, which can then be indentified via fstat(1). That special file can then be mounted by mount_fusefs. The second paragraph is even more opaque, and it goes down-hill from there. This is probably a great improvement (the old NTFS driver was ropey, although R/O was fine for me). But the documentation and implementation isn't great for anyone trying to use it. I'd be inclined to tackle this, but I don't know FUSE and I've spent enough time trying to figure it out to realise that it's best left to the gnostics. Regards, Frank.
