I`ve bought a 4GB memory SDHC memory card to my Canon powershot A 430 camera, and when i put it in my camera - it says memory card error. I tried to unlock it by the small button, but didin`t help. What should i do? Is there anywhere wherein the SDHC Card can be used on Canon PowerShot A430

The SD200 works with SD cards. Your 4GB card is actually an SDHC card. While it fits into the slot, it is electronically incompatible and will not work in this camera. You need to use SD cards, 2GB and smaller.

There are several possible causes for "memory card locked", "memory card error", or "no memory card". The most common cause is having the tiny slide switch on the side of the card in the wrong position. The second most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. There are also other common causes if the above didn't help, with troubleshooting steps for this problem listed here.

The most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. Other causes include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card). Troubleshooting tips for this problem may be found at this link. And finally, if the cards that you've been using are 4GB SDHC, that's your problem.

The A430 works with MMC and SD cards. It will not work with SDHC cards. You need to use SD or MMC cards, 2GB and smaller.

First, make sure your camera can accept SDHC cards. If the camera says the card is locked, move the slide switch on the side of the card.

I'm guessing you bought a new 4GB SDHC card. Although it looks exactly the same as a standard SD card, the format the card uses is very different. Unfortunately your camera was designed before the SDHC format came out. Sorry, but a SDHC card will not work with your camera.

You'll need to use standard SD cards (usually those 2GB or less). But if you really want to use a 4GB card, do a Google search for 4GB SD "non HC", with the non HC in quotes. Believe Transcend makes one.

It's a good bet that anything 4GB or greater is a SDHC card (look on the card, see if SDHC is written there). Your A530 was designed before the new SDHC format came out. Sorry, but your camera will not recognize this type of card. Recommend instead that you get a 2GB standard SD card. They're relatively inexpensive these days.

Apparently IXUS 55 is not compatible with a 4GB SD card. Use a 2GB and you would be fine.

SDHC memory cards are relatively new, and are sadly compatible with only the newest model cameras. For your model camera, recommend a maximum 2GB standard SD card. Fortunately, these days a 2GB card is very inexpensive.
