After inserting the new SanDisk, SDHC Card, 8GB the camera prompts "Memory card requires formatting", press continue; warms that formatting will delete everything on memory card; pres continue; "Formatting"; then prompts that it requires formattig again & again

Normally, you can only insert an SD card one way. Try a different SD card or check to see if the SD card you're using has the "write protect" switch on. If that's not the issue try formatting the card in your PC and then format it in the camera.

The Digimax A7 may not be compatible with "High Capacity" SD Cards (SDHC). If this is the case you will need to locate an SD card that is 2GB or less in size as anything larger than this is a high capacity card.

SD card wikipedia page

There are no 8GB SD cards. Cards this size are SDHC (High Capacity). SD and SDHC cards fit the same slots, but many cameras won't work with the SDHC cards. SDHC is not backwards compatible.

SD and SDHC cards fit the same slots, but many cameras won't work with the SDHC (high capacity) cards. SDHC is not backwards compatible.

8MB or 8GB? If it's actually an 8MB card, you'll be able to put maybe two or three pictures on it, so I'll assume it's an 8GB card.

The DX4530 is designed to work with SD cards. Your 8GB card is actually an SDHC card. While SDHC cards will fit into SD devices, there are electronic difference that prevent them from working there. SD cards will work in SDHC devices but not the other way around.

You need to use SD cards, 2GB and smaller.

No. Can you get into the camera menu when you turn the camera on? If so, go to "format" by way of the menu rather than clicking on continue. Also, be sure the slide switch on the side of the card is in the unlocked position.

The problem is that you're using an incompatible memory card.

Your camera is designed to use SD memory cards up to a maximum 2GB capacity. Click on this link for the user manual and look at the specification on page 43 under the heading "storage".

You're trying to use an 8GB SDHC: not only is the capacity far too large for your camera to handle, but it's a later technical standard which your camera does not have the hardware for. SD and SDHC cards may look the same, but are very different "under the skin". SDHC compliant devices are backwards compatible with earlier SD cards, but SD devices like your camera cannot be updated to use SDHC cards.

Your only fix is to replace the SDHC card with an SD card of no greater than 2GB capacity.

Get a new camera :-)

Seriously, the Z740 is designed to work with SD cards, not SDHC cards. While SDHC cards will fit into the camera, they will not work. You need to buy SD cards 2GB and smaller.

This camera's software will accomidate up to 2 GB SD card, or up to 8 GB SDHC card. Check your camera manufacturer's Help Page to learn the card capacity of your camera

Hi Tony,

Have your My Computer window open and re-insert the card into the reader. If it doesn't show immediately, then right click and choose refresh. It should show up then.
