New card not working


I have a digital camera Canon Powershot G9 and I bought the SanDisk SDXC on Amazon.  When I insert the card the camera says there is a memory card error. Ditto if I try formatting it.  Amazon site says it’s compatible with all digital cameras.  Is the card defective or what?

Thanks for help.

Well, it can be defective… But, can you write what exactly camera says? + Is the card works on the computer?

Have you tried placing the card in the card readr slot of your computer/laptop, and see if if it is recognized there?

If not, you may indeed have a defective card.
