I have a fit-pc3 device that I have installed debian 10.3 headless on a 4GB SD card and I have a 160GB 2.5" HDD I would like to use for storage in it. This drive exists, and the lsblk command lists it as sda with 10 partitions. When I tried fdisk /dev/sda it says no such file or directory. When I type fdisk -l it lists sda and all 10 of its partitions.
Does anyone have any ideas?
Edited for proper path to device that fdisk can find but can't find.
