I had a 3TB drive in my Windows 7 desktop computer filled with mostly media. I'm fairly certain I had it formatted as GPT, but I'm not 100% sure on that.

I bought a USB3 Sata dock to hook it up to my new Windows 8 laptop but it's not working. It's showing in Disk Management as a Healthy GPT Protected Partition. It's showing in Device Manager (when I go to drive properties and populate the data) that it's an MBR drive. Meanwhile it's not showing in My Computer at all. Disk Management gives me no options with the drive.

What can I do to retrieve my data from the drive?
