Comment 17 for bug 442398

Sorry, I don't know the details of the mounting process and how the system get those property information

But I noticed that Chris suggest you to change the /usr/share/polkit-1/actions/org.freedesktop.devicekit.disks.policy

Maybe you should try to change them back ?

I installed Karmic yesterday and changed nothing but deleted that file. The USB storage auto mounted in /media/<their labels>, and the properties can be accessed. But I also cannot rename the disks, unless I choose to format them in the right click popup menu. The Palimpsest shows the label of the disk but it's in gray and unchangeable. Maybe there are some permission problems?

It's so weired that many people claims no such problems even after the latest upgrades. Probably it's related to the hardware ?
