PhotoRescue
Not only will this application find files you accidentally overwrote during a reformat, or the ones you deleted "by accident," you'll also uncover photos you really did intentionally delete sometime in the past. I was amazed to discover some of the photos I took several months back, still completely intact. Another thing I like about this product is availability for both Windows and Mac OS X users - especially since I qualify as both. Essentially, this app allows you to recover files you thought were destroyed, from SmartMedia, CompactFlash, Memory Sticks, and Microdrives. In many cases, you'll also be able to recover files from other types of physical drives as well. A preview window allows you to decide which found images you want to keep, before you actually rescue them from your media. Geared more specifically toward JPEG and TIFF images, PhotoRescue will recover most common image file types. [9x/NT/W2k/XP $29]
