the following command will list all drives and partitions in your shell

BASH

sudo lsblk -o UUID,NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL,MODEL

It should look something like this depending on your drive setup

You can aso run blkid to list all partitions, not in a tree view

BASH

sudo blkid

I added a larger external drive, but the red light on the pi was blinking so, i guess it does not have enough power to handle that drive and the others

Apparently if the light blinks on the 2b it means it is not getting enough power.
