I bought a 3 TB segate hard drive. I formatted it to get rid of the segate software. Formatted it as a GPT drive and it works fine while in the enclosure. I took the hard drive out, connected it to my PC as an internal hard drive and the hard drive is recognized as MBR and I can't see the GPT partition. I connect it back to the enclosure and it works fine.

why is that?

I have other 3 TB hard drives that are internal and work fine.

The bridge firmware in Seagate's 3TB external HDDs is configured with 4KB LBAs. When you remove the drive and attach it directly to your computer motherboard's SATA port, you are exposing the drive's native 512-byte LBAs. This means that you will still be able to see the partition table in sector 0, but the actual partition data will be in the wrong place.

so is there anyway to match that bridge on the machine and how would I be able to check how the hard drive is configured, is there a software that does that?
