<br>
Here's a proposal, using sdc as the example.<br>
<br>
# Quickly wipe the head of the disk.<br>
sudo dd if=/dev/zero of=/dev/sdc bs=16MB count=1<br>
<br>
# Create a new, basic partition table. Good for up to 2TB.<br>
sudo parted /dev/sdc mklabel msdos<br>
<br>
# If you have a disk larger than 2TB, use this instead.<br>
# sudo parted /dev/sdc mklabel gpt<br>
<br>
# Create a new, cylinder-aligned, primary partition, the full size of the disk<br>
sudo parted --align cylinder /dev/sdc mkpart primary 0% 100%<br>
<br>
The most interesting part might be that last line. I found many posts by people looking for a way to create a partition using parted non-interactively that is the full size of the disk and "properly aligned for best performance", but I didn't find anyone giving the answer. So... So that.<br>
