I have had two cards of the many cards I have used and re-used become "corrupted" By corrupted, I mean that the cards previously were working, contained images, which had been viewed and deleted on the computer, and used again, in the same manner, until such time as I would put one of the cards in the computer, and viola, it would say, Unreadable, do you want to format this disk [smart media card]? So the card was working well before the corruption. Yes, and the second time it occurred was at a SmartDisk booth at PhotoShop World 2002, when man whose name I will not say was trying to demonstrate the ability of the dual SmartDisk reader he was selling, to read my card, which I pulled out of the camera and handed to him. Mind you, this was a brand new disk with only a ton of images on it from the PhotoShop World exposition, and I had just taken a photo at his booth, so when he could not get it to work, because of whatever?, he gave me back the card, and I continued to take photos. When I got home, to put the card into my reader to download the images, I got the message, "unreadable, do you want to format this disk?" So I emailed him three times, but he ignored my email. I blamed the malfunction, of course on his reader. What do you think. I normally use a Lexar reader, and i believe that I was using a 32 mb Kingston smartcard. Do you think that could be the problem? Various reader incompatibilities. These guy who was at the booth, was not a demonstrator, but rather a computer guy from Smart Disk, who was filling in for the Demonstrator of their products. I have thought of going to Ritz camera and seeing if their reader could read the images. I do not know how Data Rescue's PhotoRescue could rescue images that no reader could read? They are probably on the disk, but they cannot be seen by the reader.
