Hey,

Looks like you are trying to recover some e-mails. You may be able to recover them but it requires a little bit of computer skills for doing that.

If could download a copy of FTK (Forensic Tool kit) from www.accessdata.com and install it , it may be possible. However, since you will not be having a licensed version, FTK will be able to recover only 5000 files/images. Essentially it will bring up a list of all the images , deleted files etc.. (only upto 5000 !) . Now all you have to do is to look under various sections (like deleted files, slack space etc...) to find the file.

The other ways are complicated and requires making an image of the drive. After that you can add the image to open source tools like sleuth kit to index through image.

Additionally, you can also go to forensicswiki.org to find some tools that will do this for you.

Good Luck!
