I don't have ntsf-3g installed here, and have no use for it, and can't be arsed to install it to check :-) But, it's mount command ought to obey the usual permission model for using foreign filesystems on Unix, which is: As the models are so different and can't be mapped one to another sanely, mount fudges the permissions. Basically, it assigns the same umask and ownership to every object on the volume. The default is umask=, owner=root:root (actually 0:0), but that's just a default and it can actually be anything. Look into the docs for such mount options as uid gid umask fmask dmask The last two are from vfat, they just let you use one mask for directories and another for files (which is quite sane actually - otherwise you get every file on the volume being executable which is crazy). Assuming your uid is 1000, primary group 1000, you can then use options something like: uid=1000,gid=1000,dmask=0007,fmask=0117 which gives a sane unix-like set of permissions. Nothing close to windows but a) you don't have to be root to use it and b) the www user can't trash your files on the ntfs volume.
