   Your card reader is incapable of dealing with memory cards that are 
of that size or type.  SDHC only usable to 32 Gig, above 32 Gig the 
format changes, the name changes to SDXC.

According to the SD specifications, any SD card larger than 32GB is an 
SDXC card and has to be formatted with the exFAT filesystem. This means 
the official SD Formatter tool will always format cards that are 64GB or 
larger as exFAT.
