Hello,
I formatted my HDD and installed Windows, but when I saw that I formatted a wrong harddisk, i deleted all files from hard disk by Shift Delete. I thought maybe it will help to recover files easyer, but now, I can recover all windows files that I installed

but not old files before formatted HDD. I can see all documents all pictures files. I recover them, it says that files were recovered, but when I try to open these files, it says that file is corrupted...
How can I delete all files that I deleted after installing windows, I mean all files and folders like Windows, Program files, and documents and settings. I dont want to see these files, I want to recover my old files before formating hard drive..
Thanks....
