Currently just the first found partition is auto mounted and sd cards w/o partition table.

Currently just vFAT/FAT32 is supported, other file systems fail to be mounted due to the mount options given which just make sense for vfat mounts. (But can be mounted by hand if developer mode is enabled).

It looks like that windows native tools do not allow to format huge (>= 64GB?) sd cards with FAT32 and forces exFAT. Also newer sd cards (>= 64GB?) are now a days more often pre formatted with exFAT. Formatting the sd-card should be done with under Linux with mkfs.vfat. I'm not aware of a Windows tool which allows it?

NOTICE: Reformatting the sd card with an other supported files ystem deletes all files on the sd card irrecoverable! So before doing that, make a back up of the files on the sd card.
