If memory serves me, over in community.spiceworks.com's Data Recovery forum, somebody indicated a USB and/or DVD Linux boot containing some real good data recovery tools, I think. I read in other forums across The 'Net that MiniTools Power Data Recovery, R-Studio, Stellar, Ultimate Restorer, and so many more -- all can help, to some extent.
Thanks for the tips! Would the tool you saw on Spiceworks sound familiar if you heard it?
eg Knoppix, SystemRescueCD, Trinity Rescue Kit, Ultimate Boot CD, Lsoft Active Boot Disk, Lsoft Active Data Studo?
I'm going to start by trying these after I make a DD image of my HDD, which I really should've already done.
