I use a [Toshiba 1GB] compact flash card in my Nikon D2X and the first time I went to download the images, to my horror, there was nothing there. I was able to playback the images on my camera at first, but now, I no longer can. I know a compact flash uses memory on a chip as upposed to a hard drive, which stores data magnetically on a disc. But is it still possible to recover data from one?
