Problem with CF card

[kiwi]

Can anyone help ? When I put my cf card in my card reader it won't open the folder and I get a "you need to first format the device" message

I put back in camera and I can happily view on LCD and I've been able to load files onto via pc the cable

Whatcha reckon ?

Files are not on the /root?

There is a subfolder containing the images that the reader and PC are not seeing?

We get this occasionally at work.

I have found that if you format the card all will be good again

That is if you have copied the files to your computer

Do you normally format in the camera Darren?

I have heard that the problem can occur when you format in the reader / pc, and in all the time we have had Digital Cameras the problem has never occurred and the cards have always been formatted in the camera.

agree with the above, early on I had a similar problem after formatting the card with the PC, once I reformatted in camera no problems.

I always format in camera before each shoot

This has happened to me a few times, I think I can still open the files in Bridge rather than Windows explorer

I had a cheapie card reader that wasn't good for my cards. They gradually became corrupt in a way that couldn't be fixed by reformatting.

If you haven't already, have you tried reading the card directly from the camera too?

Could be a temporary issue with your computer and the card/card reader.
Also try a computer reboot as another option, or uplug the card reader if via USB and plug it in again(try different ports).

Have you done any computer updates recently?(what operating system?)

Yeah, tried two different readers on two different pcs
