#2. Set Up The Second Hard Drive (Initialize & Partition Disk)

To make your hard drive showing up and detected correctly in your computer, you need to initialize the disk, setting up a correct partition style, and create partitions on your disk.

So which style to select? Recommended Partition Styles:

  • MBR - Disk with 2TB or smaller capacity.
  • GPT - Disk with 2TB or bigger capacity,  or a new SATA SSD.

EaseUS Partition Master with its New Disk Guide feature makes it easy and simple for you: partition hard drive and initialize disk at the same time.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
