I had the problem. Simply using setup on your camera and formating it will solve the problem. Very simple.

To all who have received this error using memory sticks - I re-inserted the memory several times, opening and closing the memory door while the camera was on. After a few tries, the camera read the memory, I re-formatted it and worked fine. Don't give up if re-inserting the memory doesn't work the first couple of tries. Good luck!

Necesito ayuda para solucionar el error que se presenta en mi camara digital SONY DSC 75 Gracias de antemano Jose Alfredo

When inserting my Sony Memory Stick Pro Duo (256MB) into my new camera, I receive a Memory Disk Format Error (C: 13:01). Is there a way to correct this?

I found out the problem with Sony W80! try this out! slowly insert the stick and stop right when the message " acessing " appear on the screen, and keep it right there,you'll have to use your finger to hold it at that position, with the other hand try accessing your picture, or shot , or record, everything is ok.there's another way to do it: insert the stick and then slowly pull it out until the message "accessing" appear. does this mean the stick is not really fit with the socket? Sony's fault?

oh,i've just bought Sony W80 today and i've got the "reinsert memory stick" too, and i just tried pressing the memory stick hard in to the socket and turn the camera on while still pressing the stick and it work!

No kidding guys... dropping your camera on the floor works! My sis and I both own cybershots and this error happened to us both. My sisters worked after the 2nd drop and we had to drop mine a few times and bit harder to get it working again. Thanks heaps everyone!! I was about to buy a new camera too :)

Is there a program you can use to retrive MPG videos? I have a program that can retrive almost everything except that type of file which is what my Sony does video in.

YOU ARE ALL THE BEST THANKS XXXXXXXXXXXXXXXXXXXXXXXXXXXX E61 HAS GONE YOU MIGHT HAVE TO DO IT QUITE A FEW TIMES HAHAHAHAHA

I have got the same error too
