SDXC card not recognized


I recently purchased a 64GB SDXC card. It is not recognized properly by my computer or camera. Is there some type of compatibility issue?


There are three versions of the Secure Digital standard:

  • SD – Secure Digital v1.0/1.1 (Secure Digital Standard Capacity) – supports card capacities up to 2GB
  • SDHC – Secure Digital v2.0 (Secure Digital High Capacity) – supports card capacities from 4GB up to 32GB
  • SDXC – Secure Digital v3.0 (Secure Digital Extended Capacity) – supports card capacities from 64GB up to 2TB

The SD Association website has a very thorough and informative page regarding SDXC compatibility and how to use your SDXC card. Please take a moment to review the information there.

If you wish, you may also contact our team Customer Support with your computer, camera, card reader or other device make and model information and they can research whether SDXC is supported or not on your device.
