OK. I shouldn't have shouted. My basic point is that ntfs worked
very recently, and therefore we owe it to ourselves to give it some
time to get fixed. fuse is unknown, not even in head and the
performance characteristics between the two aren't known. Also, I use
ntfs to recover data from "crashed" disks because it copes well with
bad spots on the disk. None of the other filesystems in the tree does
this, and that makes it a very powerful tool for dealing with crashed
disks that others say are unrecoverable.
