I am hoping someone could direct me to the right solution.
I recently purchased a 16GB Sandisk Ultra card (the newer 30 mb/s model) when on a trip in NYC. I had 3 8GB Ultra cards and wanted a bit more room.
I shoot with a Canon 7D on the 1.22 firmware.
I was using the card with no real problem for the first few times. In late August, I was out shooting with a friend and got an ERR 02 while shooting. The error shows that “the card cannot be accessed”.
I turned my camera off, removed the card, put it back in, turned the camera back on.
Everything was fine. I thought it was just an odd glitch. Technology, ya know, stuff happens.
So this past weekend, Sept 4th, I was shooting a wedding. I was using the same card. It was about 10 GB full (wedding prep, arrival, beginning of ceremony shots on there). I get the ERR 02 message again. Without time to fuddle around, I switched to another card.
When I had free time, I put the 16GB card back in my camera and all but the last 30 pictures could not be displayed. The LCD gave me a “image cannot be shown” message.
Totally stressed, I put the card away, finished the day. When I got home, I put the card back in the camera, connected it to my PC and managed to copy over all the images. Nothing was lost.
But I question the quality of the card I bought. I searched online and I got mixed messages from firmware issues with the 7D, 7D tech issues, card issues,… not sure where to turn.
Thoughts? Next steps?
