To cut a very long story short,Lastnight i formatted my pc backing up all the work i needed on to my sisters computer,Then later that evening i put it all back on my pc and deleled the data from my sisters pc.But this morning my pc went all funny so i had to format again,Losing all my data from my pc i had before,But i seem to remember something on the news lastyear about some kind of software that can find deleted data on ur harddrive from years ago?
