I'm not sure what's wrong. In my D7000, I have two cards. For whatever reason, I occasionally switch the cards around. Sometimes my camera will tell me the card is corrupted. I switch cards and go on shooting. The other night I just took the card out and put it back into the same slot and went on as if nothing happened, and never lost a shot. Cards aren't expensive, but I'm not sure if the problem might actually be in the camera. At this point it is merely an inconvenience, but at some point, I will miss the shot. How can I test the cards or the camera. The cards are both Sandisk 8gb.

It's probably just a matter of R&R the card that helps it make a better electrical contact in the camera.

Does the problem always arise with the same slot, regardless of what card is in it, or with the same card, regardless of which slot it is in? The answer to that should tell you where the problem lies. Also, take a close look at the contacts on both cards. They should appear the same with no noticeable damage or discoloration.

You can check it for errors in windows explorer. Insert the card into your SD card reader, open Explorer, right-click the drive and select properties and under the tools tab select the error checking button.

Thank you, Thank you! I always download with USB from the camera, so I never knew that feature existed. The computer tells me everything is fine, so I'll keep track of what goes on and try to track it down if it happens again.

Glad I could help.

Are you formatting the cards before the swap? Don't know how camera would like it if there are images left on card when swapped.

Buckwheat, I know of no sure-fire way to test the integrity of a card, other than just seeing if you can perform normal operations with it, such as copying to the card, deleting from the card and formatting.

I've made a habit of formatting my cards in the camera (as someone else has already mentioned) just prior to going on a shoot. If they format okay, then I have every expectation they will perform for the shoot. I have had the experience where one of my cards would not format, and it had been working just fine up to that point.

They are kinda like light bulbs. :-)

You may have oxidized contacts. If the problem occurs for the same card in either slot then the problem would be the card's contacts. A pencil eraser can be used to clean contacts.
If the problem occurs for both cards in only one slot then the problem would be the slot's contacts which are more difficult to clean. You can buy an electronic contact cleaner in a spray can. Radio Shack would be a source or other electronics store. Use sparingly!
Hope this helps.

A camera does not normally corrupt a card. If it were that defective electronically, there would be other symptoms as well. The problem is most likely mass production and built in lifespans. Card makers have to eat too.

I appreciate the replys. I've never been able to resurrect and reuse a light bulb. Cards are cheap compared to film. Rather than take any more chances, I'll just replace both cards.

Did you format the card in its new slot before using it? If you have your camera set for RAW and JPEG and then switch the cards without formatting them, then I can see where your problem would be. I hope this helps.
