Some card readers or host devices are not compatible with the larger SDHC and SDXC cards. If the reader or host is not compatible with the larger capacity the card will be re partitioned to a size that is supported.

For example if your card reader or camera is compatible with a SDHC card with a maximum capacity of 32GB using this reader or camera to format a 64GB SDXC card will result in the card being re partitioned to 32GB (~27GB usable capacity)

If you experience this issue you will need to use a reader or host that supports the full capacity of the card and use the SD formatter to recover the full capacity.

WARNING: Formatting will erase all data on the card. Back up all your data before proceeding.
