I leave tomorrow HELP I have a Canon Powershot A530 and when I put in an 4GM memory card I get Memory Card Error

Question edited for clarity.

Your memory card is too big and beyond the capabilities of the camera. 512Mb is recommended. Page 34 of the manual

What type(s) and size(s) cards are you trying? The A530 works with MMC and SD cards, 2GB or smaller. It will not work with higher-capacity SDHC cards.

No, but it might be that new 4GB SDHC card if you're trying to use such in an A530. Please see this article for troubleshooting steps for memory card error problems.

The A530 works with SD cards. It will not work with higher-capacity SDHC cards. You need to use SD cards, 2GB and smaller.

Having gone nearly two years without a response to my query, I assume my suggestion to use an SD card instead of an SDHC card solved the problem.

Actually, your camera is probably telling you the internal memory is full. To get the camera to write to the card, you need to get rid of everything on the internal memory. Here's how...with no card in the camera, go into the menu and find "format"...follow the on-screen instructions to erase the internal memory. Then, your card should work properly.

The A530 is designed to work with SD cards, not SDHC cards. You'll need to go with cards 2GB and smaller.

When this problem occur you need to set the memory card unlock or not protected. Remove the memory card from camera and you can see a small button in the memory card, so you need to slide that to set the memory card unlock or not protected.

Check the slot and see if the pins inside are fine, no breakages, free from dust etc. Try turning the camera on and off (completely remove batteries etc).

Connect your memory card to a computer by using a card reader. Format the memory card in your computer treating it as a hard drive. Good luck!
