There might also be the issue of the card reading hardware only supprting SDHC instead of SDXC (or SDUC).
- kop316 6y agoThat is true, though I have yet to run into that issue though for the devices I have tried it on (which admittedly is not a large sample size).
- kasabali 6y agoEven then it is actually only a driver or firmware limitation most of the time. My old laptop has Ricoh SDHC card reader. Windows can't read 64GB SD cards (properly formatted with exFAT according to the standard) on it because it's using the proprietary Ricoh driver. On Linux it works just fine because it's using the generic SD card reader driver which supports SDXC.
