And there wnet the tale of the Data Back-up did it not.
Not all lost though as you might still be able to recover some of the precious data from the HHD, this link, and yes you will have to purchase it's registration number, will allow you too recover files from the laptop hard drive, you will need another working computer and possible a caddy for the laptops HDD as well to do it.

There are also a number of free and shareware utilities available on the net but this one actually works and I use it on a regualr basis.
Walkthrough tutorials are included on the web page.
Oh when you next go to the store, buy a pack of C/D RW to back up what you recover. Just a thought to keep Mrs off ya case.
