Been a long time since i last posted on this forum :P
For a little while I have been curious about data recovery programs for the mac; by that I mean actually creating one from scratch. I know that this isn't the best area to post this question but the software, i would imagine, may have to be created using the Xcode application of OS lion. Or failing that using a software language I am familiar with; like java.
So does anyone have any experience in this area or should I rely on ready made expensive software for my solution?
