|reformatting was not a good decision, you could have tried a repair install thus not losing all your data.|
For lost pics and documents I have used file scavenger. It has a demo that you can see what files are still on your PC. Then you pay for the program to get it.
The more you add to your PC, the more you will lose what was on before you reformatted.
Someone else may have some different software in mind for recovery. If no-one answers this post, try reposting asking for recovery software. File Scavenger was the only prog that worked for me, I saved tons of documents as well as loads of pics from a PC that had 8 yrs of stuff on it before it was reformatted through the advice of Dell (they never told her to save her data before reformatting).
Some HELP in posting on Computing.net plus free progs and instructions Cheers
