Can anyone point me in the right direction for recovery software .... I accidently put an operating system on a hard drive by accident and I've lost all me photos and basically 10 years of work. .... I'm at the desperate stage now lol ....
The best thing you can do is to stop adding things to the computer until you are sorted.
My experience is that most of the free programmes aren't great, and it may take a professional which is damned expensive.
The program mentioned above is probably the best one out there, but try them all. I know it's too late now, but invest in an external hard drive for backup.
