Gigabyte has published 3TB+ Unlock Utility, a new application that enables Gigabyte motherboards with Hybrid EFI technology to recognize and use unallocated space on new 3TB and larger HDDs. You can download this tool over here.
GIGABYTE 3TB+ Unlock optimizes HDD storage space by allowing the user to create a virtual drive with space that exceeds 2048GB, the maximum amount of storage recognized by 32bit versions of operating systems such as Windows XP. The virtual drives are limited to 2048GB, and the user can create up to 128 partitions, as long as there is additional unallocated space on the HDD. 3TB+ Unlock supports both GPT (GUID Partition Table) and MBR (Master Boot Record) partition styles, however with MBR the number of partitions are limited to 8.
3TB+ Unlock currently supports new high-end motherboard models based on the Intel® X58, Intel® 6 series and AMD 8 series chipsets, and is in the process of being ported to older chipset models so that it will support all motherboards that are currently shipping.
