there was some data in my laptop and suddenly its window became corrupted and i have to reinstall the window xp in it again and after that i could not find my data in the laptop. i came to know that it is stored in the hard disc of my laptop and it can be restored with the help of a software. so i want to know the information of that software and also want to know that whether the software could be downloaded free from the internet for my personal use for trial.
