External USB Drive Problem in Fedora 14


I am getting "USB" drive error while inserting into USB Port in Fedora 14 i386. Yesterday, I was getting auto mounted drive of any external device,but since today morning, below error has occurred.

Using "tail -f /var/log/messages" command giving below output.

"fdisk -l" command is also not showing the drive volume label.

Please let me know how to mount "USB" external drives automatically? What was the problem & which file i need to check to troubleshoot the problem?

Advanced Thanks If Anyone Found Solution.

Two possibilities come to mind:
a) have you run a system update between last night and this morning. If so, the udev rule governing external usb drives may have changed.
In a terminal, run "ls -l /etc/udev/rules.d" (or whatever the path to the udev rules is in Fedora). Run the command without the quotes. If any of the files changed between last night and this morning, you may have to edit one of them the get your usb drive mounting automagically again.
b) there is a right way and a wrong way to unplug an external hard drive. The right way is to unmount the drive, then stop the platters spinning before unplugging the drive. That is to prevent physical damage and also prevent possible data corruption. The wrong way is to simply unplug the drive while it is mounted and spinning.
So, you may have to consider the possibility that the drive is damaged. Test it by plugging it into another computer.

Boot to live cd and then see if the usb mounts correctly.
