Easy way to undelete from a Sony DSC-T5

(and probably many other cameras too)

I realized recently that I had deleted a picture that I kind of wanted to keep.  I deleted it using the interface on the camera, not by hooking it up to a computer.  Happily I hadn't taken any pictures since, so I figured on a reasonable chance of reclaiming the picture.

I was successful, and it was easy.  I used PC Inspector File Recovery.  The interface kind of sucks, and the hardest part I think is selecting which drive to search.  It did pick up the the FAT partition on the camera over USB though, which was good as I had half expected Sony to have some middle layer in which the camera represented the pictures it could see on the card to the computer (in which case I would have had to put the Memorystick in a separate card reader).
