Similar problem. I have a music player that acts as a usb vfat storage. It is now mounted with root rights only so I cannot change its contents.
I have an edgy eft laptop besides this feisty box and it works fine. On edgy it mounts as /media/usbdisk, on feisty it mounts as /media/disk (which is weird to me). I am attaching screenshots and a small screencast demoing the problem. ** Attachment added: "screenshots / screencast" http://librarian.launchpad.net/6629591/media-disk.tar -- Kubuntu Edgy: Can't write to USB stick https://launchpad.net/bugs/88147 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
