cfdisk

tune2fs: Bad magic number in super-block while trying to open /dev/sdb
Couldn't find valid filesystem superblock.
The issue above seems to be that you're trying to use an e2fs tool (tune2fs) on a device that contains a single VFAT file system. Before we go any further, could you say whether you want a vfat or an e2fs filesystem on the USB stick? Could you also say if you get the same write error when you do
sudo cfdisk /dev/sdb1
