Sorry to barge in, but should there be a mount point created in /mnt for it, for example:
sudo mkdir /mnt/Pendrive
sudo mount /dev/sdb1 /mnt/Pendrive
Not sure where this command mounts it to:

sudo mount /dev/sdb1 /mnt
? Or am I missing something? I'm aware you are fairly expert, sudodus, so I probably am missing something.
