I bought a Maxell 8gb 400x cf card and it failed almost immediately. It seem to write the images okay in the camera (a Canon 50D) but failed to read them in my PC. When I put the card back in the camear all the images were gone. I have never had any trouble with my SanDisk cards so I returned the bad card to Maxell for replacement. I got the replacement card and had the exact same thing happen. To be sure that it's not my camera or computer I repeated the experiment with a couple of my SanDisk card and all is well. The moral to this story is to stay away from Maxell!!!
