Comment 8 for bug 163386

Still doesn't work. I ran fsck and it modified the FAT partition a little, which caused it to show up in Computer as a "black drive" but it sill won't mount if I click on it. It gives me error message "Invalid mount option when attempting to mount the volume" and "DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

Every partition mounts just fine if I do it manually. Why won't the computer recognize them automatically?
