Waiting for more information (see comment #1).
(In reply to comment #1) > Can you access it from a terminal? No, can not access from terminal. btw, if use "umount" & "mount" in terminal, and try it for serveral times, can access successfully.
We guess if the device has not been cut down power under kde env.
Can you try restarting a daemon called either "udisk" or "udisk2" ?
Closing the thread for lack of activity. Please, please! if you are still able to reproduce this with KDE 4.10 feel free to reopen the bug!
