I formatted a 8TB Seagate IronWolf hard drive via an external USB enclosure. It worked fine: Windows 10 recognized both GPT partitions:
- Partition 1: GPT, 128 MB
- Partition 2: GPT, 7451 GB.
But when connect it direct via SATA, Windows recognize the drive as MBR:
- Partition 1: MBR, 2048 GB, Protective Partition.
- Unallocated: 5404 GB
When put the drive back into the USB case, all works fine. How can I force Windows to recognize the hard drive type as GPT?
Setting the partition type id with a tool like Partition Wizard, doesn't make sense, because the drive which holds the partiton, is recognized as MBR. Of course I dont't want to reformtat it, because it holds a prtition with data. Software like Active Partition Manager stops on a convert to GPT action with: "Unable to convert GUID Partition Table. Impossible to place partitions outside of target area on devices having GPT".
Hardware details:
- Windows 10 x64
- Seagate Archive HDD v2 8TB (ST8000AS0002-1NA17Z)
- AMD Ryzen 7, Asus Prime X370-Pro
Correct recognized partiotioncs (via USB):
- Partition 1: ID=E3C9E316-0B5C-4DB8-817D-F92DF00215AE (GPT, 128 MB)
- Partition 2: ID=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (GPT, 7451 MB, Encrypted via VeraCrypt)

Wrong recognized Partitions (via SATA):
- Partition 1: GPT Protective Partition(GPT, 2048 GB)
- Unallocated: 5404 GB

Any idea why its not possible to operate my drive internal?
