external hard drive not detected after ubuntu crash [restarting machine]
- by Netmoon
today i tried to watch movie [with vlc media player] from my external hard drive [expansion portable 500 GB], and it's play good, then pause the movie and play it again, and my Ubuntu crashed! [Ubuntu 12.04]i had to restart the machine, so did it, but after that Ubuntu can't recognize this hard drive! i changed USB cable but it was not effective.
this is my dmesg command result :

note:
I am able to hear the sound of the external drive lens.
When attach hard drive to usb port, the status light goes on, but it's low bright and i think its power is low!
try to mount in Microsoft Windows 7, but nothing happened.
