=OK, Let's do it=
First we label the drive with a GPT partition
{{Code| parted /dev/sdb mklabel gpt}}
Now we select sectors as a unit of measurement
{{Code| parted /dev/sdb unit s}}
Now we make the partition.
{{Code| parted /dev/sdb mkpart primary ext4 2048 -1}}
Parted may complain about the last sector and will automatically suggest a correct sector, just say Yes to the prompt.
