Having taken 150 or so pictures on my holiday, get to the last day and the memory card suddenly gave up the ghost. It is unreadable in any camera and my PC card reader. Jessops had a look and returned it. It's a Kingston 512mb compactflash, used in a Nikon D70. Kingston will replace it but then of course I lose all the pics. Does anyone know of a data recovery service - the stuff I've found on the web is more about recovering corrupt or deleted files rather than an unreadable card?
