if you call fdisk you see what disk you use.
Here Sven thought, makesd would access /dev/sdg
but did access /dev/sdc!

That is a different thing.
fdisk does not do any writes when it is called without a device name to
work on!
makesd does.

Sven's sudo construction is just equal to calling
makesd *without* DEV set!!!

In that case makesd should not take a predefined device.

Maybe makesd also should display a list what it wants to do
asking for final confirmation

The best thing would be to call makesd from NAND with a graphical

No, that would not work, because you want to mount the device and
create device nodes on it, which would require root privileges again.
