Problems with 20D

[adcolon]

I have a Canon 20D which has worked perfectly for the past 6 months. Yesterday I was using a SanDisk 2 giga Ext. III to take some pictures and when I tried to download them to the computer I got a message saying the compact flsh card was empty and asking if I wanted to reformat the card. I put the card in the camera and could see the pictures. Since I needed the pictures I bought a program called PhotoRevovery and was able to download. I next tried a Lexar compact flash card and the same thing happened. Has anyhone had a similar experience? In the camera damaged?:cry:

do you use a cardreader or the cam to download the pics to your PC?

Did you try to format the lexar card? (with the cam, not the PC)

Like GeForce said, always format a card in your camera before you use it. I always use a card reader, you must be using one of those if you're using an image recovery program, right?

I use a cardreader to download. Actually I have two. One SanDisk and the one that came on the computer. And I always format the cards in the camera before unsing them. The funny thing was that I could see the pictures in the camera but non of the readers, including using another computer could see the pictures. Today I used the cards again. The Sandisk worked perfectly (after using the recovery program to "wipe" it, but the Lexar continued to give me problems. Then I mounted the lexar on another computer (which I had done previously without results) and it worked perfectly.

Can you run a byte level scan on the card using windows? Ie write to the card and read it, and see if it works? Not sure what program does that.

If you write anything at all to the suspect CF card, you might be overwriting some image files that have not been recovered yet.

Before you do anything, you should attempt image file recovery.
