When you add a new disk into your machine, you should initialize it before it can be used for storing and retrieving. In other words, a new added disk must be registered in your operating system by initializing it. This feature allows you to initialize a disk into MBR or GPT mode.
To Initialize Disk
Step1:Launch AOMEI Partition Assistant and right click on the raw disk which you want to initialize, let's take Disk 2 as an example. Choose Initialize Disk in the pop-up menu.
Step2:In the pop up windows, there will be two options for you to choose. You can initialize the disk to MBR or GPT style. Click OK to continue.
Step3:Click Apply to wait for process to complete.
The Initialize Disk option will be grayed out if the disk has already been initialized.
