My harddisk is broken

Bad news again for me, that i have to lost some of my data that i didn't save it to dvd, it because of my harddisk is broken and can't be used again. Last night i try to back up after office hour, but it only detect usb but not the harddisk, so i just try to ask my friend, if he know something to repair it so i can make back up data again. But... i heard from him, this harddisk is broken/died.
Arkkk... but lucky me, i still can save some photos and some data from that.
Good bye my data :(
