Hard disk failure

First my laptop didn’t want to boot. Then while backing up everything to external drive it also failed. I bought new 250GB hdd and replaced the old one but now I’m listening to weird noises from right fan beneath my keyboard. Yyyy :/ Is seems that I’ll have to open my laptop once again..

Most of will probably ask “Do you have any backups?” Hmm. Yes I’ve backed up all my projects. But some of my music, videos and photos are lost. We will some how much I can recover from my old disk.
