I have some drives of various sizes, 1TB, 2TB etc. I am currently working with a 2 TB drive. I place it in a powered external USB-3 drive enclosure. I can see it in lsblk as the correct size (as SDA) , but the disk manager does not see /dev/sda, and fdisk only wants to let me create a 5 GB partition.

If I dd if=/dev/zero of=/dev/sda bs=400K status=progress writes 5 GB and claims my 2 TB drive (In this case) is full.

Is there a way to reclaim this drive? Any information on the drive is unimportant.
