Can not mount volume

benny, ask please with more circumstances in order to understand your question.

yes the alert box said cannot mount and the description print Error org.freedesktop.DBus.Error.AccessDenied.
see message bus configuration file (rejected message had interface "org.freedesktop.Hal.Device.Volume" member "Mount"
Where the come from org.freedesktop and whats that?
What circumstances mean anyway...
I have try with live cd and mount disk is working properly

Yo!
I go to synaptik paket manajer found:
FreeDesktop.org shared MIME database and spec
This is the shared MIME-info database from the X Desktop Group. It is required
by any program complying to the Shared MIME-Info Database spec, which is also
included in this package.
At this time ROX and GNOME use this database. KDE is expected to follow soon,
and hopefully others too.

Do I should remove the software? but many software will remove hmm
How to?

Hope circumstances above help you to understand my question, now the disk still unmount in 2 days. Have you ever have problem with mount and unmount disk pasca/after org.freedesktop enter your system... pass it what?

Unfortunately it is possible it is a bug.

"Don't seem like a lot of people have actually used Linux much. They haven't had to deal with an updated Enterprise Linux distro making their screen go blank because the X server crashed, or boot them out to a command-line log-in. Or some of the wireless problems some users have. Or the shoddy hardware support that Linux gets from a lot of vendors (long waits for driver updates after a kernel/OS upgrade)"

or... look at me my disk can not run! 3 days to search help find no solution to fix duh

If you persist with Ubuntu the lightest way is reinstalling Ubuntu. If it is successful you will not need periodical reinstallation like with Microsoft.
Keep in mind Linux comes with a lot applications and you don't have to pay for them. Naturally they come with no guarantee. But does MS satisfies it's own guarantees?

My advice is: try installing Ubuntu once again, better from LiveCD.
