IMO, only 2 brand of card is good. Lexar and Sandisk :thumbsup: :thumbsup: :thumbsup: . I will not risk my photos for the cheaper prices of other brands. Money cannot buy precious moments captured in the photo. Imagine if you shoot your friend's wedding and your card failed at the end of the day without backing up... :angry: ;( Safest way is to invest a good card and backup frequently.
i have a Lexar 1GB, and it failed me a few months ago, it has this message for some of my images "No Image Data" and it will hang my D70s, the LCD which usually displays how many images left to be shot, it will display CHR instead. then i got to off the camera, take out the card and put it back in before it works again. The last shot will however be corrupted.
It's very frustrating and i know how you must feel.
