If it's a SDHC your PC card reader must support SDHC
Older readers do not support High Capacity card reading.

I had the same problem with my K20 when I bought it. I was using a USB 1.2 4 way hub.

I replaced it with a USB2 hub and all was well.

Are they SDHC Cards, by chance? Some card readers are not compatible with cards over 2GB (SDHC). I had to replace my 4 year old card reader when I went to the high capacity cards as the SDHC standard wasn't in effect at the time it was made.

I'm betting you didn't format the cards did you?
You will need to download the files from the camera and then format the card.
This presumes that your reader is compliant with the cards.

Most likey the reader does not support sdhc.

SDHC cards are usually larger then 2gb.

You can find a few 4gb non-sdhc though. Transcend makes one.

If your usb reader supports sdhc it will not matter what version of USB your computer has. It will just read/write slower using usb 1.0 vs 1.1 or 2.0.

Your OS should be able to read whatever is on the card regardless if its in fat 16/32 or ntfs. Formatting is not needed just to read it if your camera has already written pictures to it. The only way this would be needed was if you formatted it under linux using ext3 or 3 and windows wont read it without extra drivers or hfs+ mac format for that matter.

Thnaks for the fast responses. However I do not think it is the type of reader or the type of card: One of the 2 cards is a normal SD card.... And the card reader is a USB2.0 one .....

I did delete the pictures in them on the PC using windows explorer, and then started using them again in the camera....

My old PC didn't recognise the SDHC cards but it downloaded the pictures when I connected the K10 to the PC via the USB cable.

Hey Pieterpost, try this. Once you delete the photos, put the card back into the camera and format the card in camera. Always format the card in camera. I reformat the card everytime after making the transfers to the computer and I never experience this problem.

Two thoughts:

1) Bad card reader? Certainly not the first time I have seen one fail.

2) Assuming you are using Windows, do not use the "Unplug/Eject" hardware before you pull out the SD card from the reader. This will actually turn off the reader and you will need to reboot the computer.

If you are having to do that, there is a problem. The last time I formatted my main card (Sandisk Extreme III 4Gb) was a year ago.

There is a card generation in between SDHC and SD, (for example, the sandisk ultra II 2gig); it doesnt say SDHC but the tech is already different from normal SD cards. Are you sure that your reader can read SDHC?

While you figure the issue out, in the meantime you can use the cable that comes with the camera. (*edit: I see that you are already doing this)

I think this is an old advice from the early days of digital. I see no harm in doing it so that you have a "fresh" card though. I still do this myself as I feel safer doing it than deleting the contents in my PC

1. Try connecting the camera to the computer with the USB cable and uploading the photos that way.
2. Try putting the card into a card reader and plug it into a USB port instead. (I have found that card readers on my computers sometimes fail to read the card). If that works, the problem is to do with the built-in card reader.
3. If neither USB connection works, try the card in another computer if possible. If it doesn't work there either, I would suspect the card (even though the camera can read it).
