Format 4k ext4 hard drives properly

Find out which device you want to format. In the following example we will assume it’s /dev/sdb This example will create a ext4 partition spanning the entire size of the device, making sure it’s aligned to the sectors and while we’re at it, we’ll remove the reserved space allocation so we can use the entire space. parted --script /dev/sdb mklabel gpt parted --align=min --script /dev/sdb mkpart primary 0% 100% parted --script /dev/sdb print mkfs.
