Unusual CF card problem?

[mark_stephan2]

<p>I shoot with Nikon and Canon. Last year I purchased two Kingston 16gb 600x Ultimate CF cards. When I use them with the Nikon D300s I get a message when I put the card in the computer to look at pictures. The message says <strong>Scan and Fix or Continue without Scanning</strong>. I usually choose Continue without Scanning and I get to see my images. The cards are always formatted in camera. Now if I use the same two Kingston cards in my 40D or 5D I don't get the messages and they work perfectly. I always format the cards in my Canon camera's when I use a Canon body. <em><strong>Have you ever heard of such a thing?</strong> <strong>Why the messages with the Nikon and no messages with Canon?</strong></em> With the Nikon body I've switched back to Sandisk 16gb Extreme cards and I don't get any messages when I put the card in the computer to view pictures? It seems like a compatibility issue. <em><strong>Could it be that the cards were made for Canon and not Nikon?</strong></em> I've never heard of such a thing but I guess it could be possible! Can the 40D and 5D take advantage of the 600x speed or the 16gb size of the cards?</p>

CF card problems are EXTREMELY unusual for FD cameras, Mark!

<p>If you shot a little more with the Canon, you'd be on to the fact Rick refers to. ;)</p>

<p>For better or for worse, there are no digital Canon FD cameras. Ask a moderator to move your post to the Canon EOS forum, but frankly, I don't think that the cards are made for any one camera marque. This would be close to madness for any manufacturer, and I can't imagine why anyone, much less Kingston, would do it.</p>

<p>However, the problem could be with your computer or its built-in card reader, if that's what you're using.</p>

Read the responses to the thread that you started yesterday.</p>

<p>I get that response everytime I put any USB Flash drive into just about any computer, but I virtually never get them when accessing CF cards. My understanding is that, often, it is the computer, not the card. Windows is annoying to the extreme in this regard.</p>

<p>In answer to your question: Can the 40D and 5D take advantage of the 600x or the 16gb size?</p>

<p>Yes, they can both take advantage of the 16gb size. They can also utilize 32gb cards, though I never used 64gb cards with either, so I am not sure if they can read those.</p>

<p>No, they cannot utilize the 600x speed fully. The 5D can write no faster than ~13MB/s, and the 40D caps out at under 20MB/s. For either camera, a 133x card is as fast as the cameras can fully utilize. Neither supports UDMA.<br>

However, a faster card will likely increase the speed at which you can download images to your computer. </p>

If you use Windows' "Safely Remove Hardware" before removing the card from the reader, next time you put it in, it should not show that message.

Try formatting the cards in your camera's first, before taking any shots. Don't switch the same cards

between cameras without formatting. I've heard of this happening before. It's uncommon but it does happen.
