I like parted or the gui version gparted, but I also have fdisk and sfdisk. There's a live CD of gparted which can probably also be written to a USB stick or a small SD card in a reader. Having it on an independent device means you can use it on about anything, from a new hard drive to an SD card. Most of my old favorites won't deal with drives as big as 1 TB so I had to find something new.
https://sourceforge.net/projects/gparted/ Parted (not gui) looks like this: hp# parted GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands.
