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. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
