I shot over 3.5GB of pictures on my 4GB SanDisk Ultra SDHC card. This is the card that is always in my X100 and I usually format the card in camera after I transfer pictures to my computer. Never had an issue till date. The card shows 3.65GB of data used (54.5MB free) when I check properties in windows explorer. But when I browse the file system, it shows the directory structure on the Panasonic LX5 with 12 pictures in the DCIM folder! No sign of the Fuji folders or the pics! I have reformatted the card on the X100 at least a dozen times since I used it with the LX5. I've tried connecting the camera directly to the computer, as well as plugging in using a card reader, with the same response. I tried using a SD card recovery software, called CardRecovery, which scanned the sectors (apparently) and did nada. Just threw up the same 12 Panasonic pictures. The SD card still shows 3.65GB used space in Windows Explorer, after running the recovery software. Any ideas what to do next?
