I'm running Fedora 11 Rawhide with the latest updates as of today. My internal disks used to automount in Fedora 10 but now I only get an error when clicking on them in nautilus. External disks automount though. The error message: "Could not mount volume org.freedesktop.devicekit.disks.filesystem-mount-system-internal auth_admin" I guess that this problem is caused by the move to DeviceKit instead of Hal. All the internal disks are SATA and the partitions are formated as NTFS. Tell me if you need any more information!
