Problems with inserting a new lexar SD card

Are your computer's card reader and camera compatible with SDHC cards or only with SD cards? While SDHC cards will fit into SD devices, they are electronically incompatible and will not work in devices not designed for SDHC cards.

It's a lost cause. The A540 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in devices not designed for them. You need to stay with SD cards, 2GB and smaller.

If it's still a usable card, I would suggest just placing it back into your camera and then connecting it via USB cord.

If that doesn't work, check if your computer has a slot for SD cards. If it does, try placing the card in one of the slots gently.

The DX7440 works with MMC and SD cards. While SD cards fit into the slot, they are electronically incompatible and will not work. You need to use cards 2GB and smaller.

The V530 works with SD cards. Your new 8GB card is an SDHC card. While SDHC cards will fit into the slot, they are electronically incompatible and will not work. You need to go with SD cards, 2GB and smaller.

I suggest formatting the card using the utility in the camera. This will delete any data that is currently on the card.

Use the camera to format the SD card not your computer. There should be a menu option to format it.

I am not sure this will work, just a suggestion

Try inserting the micro sd card in the larger sd adapter that will allow you to put it into your computer reader. Try formatting it there instead

Honestly, it is most likely a defective memory card or not compatible with your camera. Sorry.

Usually the memory card (which is what the SD card is - it is like film for a non-digital camera) is inserted in the same area as the battery or batteries. If you open the battery compartment, you may see a slot next to where the batteries are placed. You should insert the card with the metal parts in the same direction as the matching ones inside the slot (there may be a small diagram on the door of the battery compartment).
