Hey, I have tried so many different approaches as to how to solve this error. I have a DSC-F707. I have 3 - 128mb memory sticks and 1 - 64mb memory stick, all Sony and all the sudden non of them were reading it would pop up the same error. I tried the ERASER, I tried messing with the little prongs inside the camara that touch the memory sticks, I tried inserting each memory stick rapidly for more than 10 times and nothing ever worked. My last resort was a post on page 4 at the bottom about someone that bangged the camara a bit out of frustration and fixed it. BANG THE CRAP OUT OF YOUR CAMARA!, in everywhich angle. The first 5 blows didnt do it so I tried different areas to bang the camara and after like 10 times hitting it medium and softly with my palm it finally started reading ALL the memory sticks. I formatted them quickly just incase, but I dont think that that was the problem with my camara. USE THIS ALTERNATIVE AS YOUR LAST IF YOU DONT WANT TO PAY MONEY. I strongly recommend banging your camara to an extent that you dont break it if all else fails. HUGO

I got this same error. I looked inside the slot and everyhting seems fine. The tabs on both sides looked fine. I've tried newly-reformatted disks as well as disks that had pix previously taken/saved on this camera. I still can't get rid of the error message.

Hi, I have the same problem, according to the manual if it is now a disk that was not formatted correctly, then it states the battery level of the Floppy Disk Adaptor for Memory Stick is low. But nowhere in book does it show where this other battery is? Or if we can fix on our own.

Check out the message I posted a couple of months ago to see how I fixed this problem. The link is below.

Be sure to reformat one of your floppy disks (using your computer and floppy drive,) after you adjust the little metal tabs that are just inside the floppy disk opening on the camera--to make sure they are straight and not bent. If one of the tabs is bent a little, it can cause this error message on the camera. But my camera didn't start working again until after I reformatted a floppy disk on my computer and inserted it into the camera. Then the other floppy disks worked fine after that.

Hope this helps.
