I recently lost a file because I reformatted my computer and forgot to back this file up. As soon as I realized my mistake, I panicked and sought data recovery software, and found GetBackData. As I was loath to disconnect my hard drive (i use a laptop) and slave it to another computer, I wrote an image of the hard drive onto an external drive and decided to hope for the best. However, when I run scans, all I find is the files that are already readily available on the drive. What am I doing wrong?
