There is nothing as sad as having all your important data disappear right in front of your eyes. All those music collections, the movies you had saved, the documents your whole life. As for now your computer is as good as dead with out the data you relied on a lot. your heart is racing fast, you know its all over and there is nothing you can do to bring it back. You take it to the computer fix shop and they to give you the sad news.
Actually there is something you can still do to get the stuff you value most.
If you have tried using data recovery software's and you still don't get anything out of it try to place it in the freezer.
A hard disk contains plates inside it and niddles that read and write information on them. They are very sensitive and the niddles are so close to the plate surface even a small dust particle can make it crush. That's why hard disk drives are air proof. if he niddle became lose and lost its position its probably touching the surface of the plates making it impossible to read the information on the disk. but placing it in the free the metal niddle will contract and regain there original shape allowing you to harvest as much information from it as possible. This method is not permanent, as soon as the hard disk becomes warm it will lose its position. but you will have collected some data from it. you can try it again until your feeling satisfied.
