Do you have an Hitachi hard disk drive that's 3TB or greater, but your Windows system can't support it? The Hitachi GPT Disk Manager solves that problem. It’s an easy to use software application that's designed to overcome the 2.2TB limitation of Windows systems. With the Hitachi GPT Disk Manager you can tap into the full capacity and power of your Hitachi ultra-capacity drive as one massive data drive without having to install new hardware. The Hitachi GPT Disk Manager works by augmenting your Windows systems to add support for GPT (GUID Partition Table) for hard disk drives exceeding 2.2TB. It can also help you create and format new partitions.
