Is 3TB enough? Because there are reasonablly priced 3TB disks out<br>
there. I got two WD Green ones for backups.<br>

The trick is to use parted, with some trick that I forgot now (but<br>
easily Googleable), because fdisk does see over 2TB.<br>

2TB is still a limit anywhere in Linux these days!!!<br></blockquote><div><br>No. Not anymore. <br><br>I have the 3TB drives with a 3TB partition and filesystem on it. <br><br>Basically, you use parted (not fdisk), and create a label as gpt.<br>
