I tried the various methods to format my 64GB Micro SD card described here, but none worked on Windows XP, Vista, or Win7computers. Not using USB or SD card slots. Not using SD Formatter. I tried all combinations of FAT32, NTFS and exFAT. They all only detected a physical size under 32GB. Typically 26.5GB
I then entered the 64GB Micro SD card into my digital Panasonic Lumix camera and it detected 58.5GB and formatted it using exFAT file system in seconds!
