I have used several products (probably four or five) to recover data from corrupt disks, both on the Mac and Windows platforms. The only one to work consistently well is Lexar's Image Rescue. Unfortunately, it only works with Lexar media and only their USB enabled CompactFlash cards. I frequently work with government agencies which may have dozens of cameras in the field, with hundreds of memory cards in use. I have recommended that they all move to Lexar cards because of the success I have had with their software. Many have, and have indicated similar success.
