Currently the SD arrived with a FDISK Partion Table and 4 partitions:
]fill to align to 2k sector/:m]
]4190209 sectors for MBR Partition (FAT32) which is not encrypted - which is around the 2.1 GB shown when the stick is connected/:m]
]22727680 sectors free ( which I assume to be the encrypted section ) - which is around 10.8 GB only/:m][/ul]
So I wonder:
Is Nitrokey Storage using a normal FDISK Table ? Or just code it as FDISK to be recognizable ?
What kind of file systems are supported ? On macOS Sierra, there is no FAT32 ( only exFAT ~which might be similar , but not recognized as such)
The current table doesn’t show the full capacity of the SD Card. Can I use a standard SD card inside Nitro Stick ?
Is there any hint/documentation (beside the source code ) to find out how the SD card is formatted ?
Any help is appreciated as I still struggle with the portions and hidden volumes. I also want to give the encrypted partition more room and so wonder, if I could re-format/partition the SD card different with a smaller size for the standard functions
I found the following in your source file git://nitrokey-storage-firmware/src/CON … _mmc_mci.h
#define SD_SIZE_UNCRYPTED_PARITION (1024*2*2048) // SD Blocks a 512 Bytes = 2048 MB
#define SD_MAGIC_NUMBER_HIDDEN_CRYPTED_PARITION 0x23636923 // u32 for secure
#define SD_START_HIDDEN_CRYPTED_PARITION (1024*2*1024) // SD Blocks a 512 Bytes = 2048 MB
Do I need to assume that you have hard-coded the partitions ?
