Not sure, but perhaps it is a plugdev group issue?

or in a more flexible way, practical if you have several users, allow
for instance the users in the plugdev group (usually those who are meant
to be able to mount removable disks, desktop users) to create files and
sub-directories on the disk:

    *   sudo chgrp plugdev /media/mynewdrive
        sudo chmod g+w /media/mynewdrive
        sudo chmod +t /media/mynewdrive

The last "chmod +t" adds the sticky bit, so that people can only delete
their own files and sub-directories in a directory, even if they have
write permissions to it (see man chmod).
