FAQ:

The solution for booting a hard disk drives beyond 2.2 TB.

Most legacy systems built before 2011 have a traditional PC BIOS. This type of BIOS uses a Master Boot Record (MBR). The MBR Partitions can define a disk drive capacity up to 2.2TB. Windows operating systems that boot from an MBR are therefore limited to 2.2TB per MBR. Such as a 3TB disk drive in a legacy BIOS and Window system will need a DiscWizard device driver to access the full capacity of a 3TB disk drive. Two partitions will be necessary because of the MBR limitation. The device driver mounts the capacity above 2.2TB with another MBR which looks to the system as a second virtual “physical” device.

GUID Partition Tables (GPT) can define drives larger than 2.2TB. You can use GPT today on any Windows 10/ 8.1/8/7 and Vista system as a non-booting data drive. Windows can only boot a GPT partition on a new type of BIOS called UEFI.
