Data there one minute - Gone the Next. Cheers for the help !

Hi All, I have had an issues with my 32 Gb sandisk CF card. I have used this card many times over the last 2 years and had no issues. 

I have shot video on my 5D2 and the file data has disappeared.

It showed 700mb in the file details when i plugged it in to Mac and now it shows 0kb only moments later

There is a thumb nail clip but the data for the actual video clip is not there…

I have tried to play the file on the camera and i get ‘Cannot play file’ message. 

Many thanks in advance.


Seems like  we both have more or less similar problems using Canon DSLRs on Mac computers. Mine doesn’t register on the download (see my peparate post)
