I partitioned a microSD card (
mmcblk1) into two partitions
If use a dedicated card reader I am able to see the entire SD card and its partitions using various disk management tools on my PC.
I am able to mount both partitions on my Android phone. However when I put my phone into USB Mass Storage mode, only
mmcblk1p1 appears as a drive letter on my computer.
mmcblk1p2 remains mounted and usable on the phone.
Isn't the partition table (GPT or MBR) stored outside of
mmcblk1p1and thus not accessible to the computer?
Assuming (1) how does the computer clearly show a disk with only 1 partition in various disk management tools as if it was a physical disk? Is the phone's Mass Storage mode performing some kind of abstraction?
What exactly would happen if I partitioned this disk on the computer? Would the phone then see a new
mmcblk1p3. How would it even be possible without access to the real partition table?
