Hello friends! Recenttly I've bougt an external USB 3.0 HDD - Samsung 3TB D3 Station (model: STSHX-D301TDB). This device has a 3TB Seagate ST3000DM001 (Barracuda 7200.14 series) inside. Because I don't need so much storage space on an external drive i want to swap the HDD inside with a 1TB from my desktop and install the 3TB drive inside my desktop, where it's needed and it's more secure. I found this step by step guide for the disassembly of the external drive, and i managed to remove the HDD from the plastic case without any damage to the case, so I still can reassemble the drive in case of waranty issues . So far so good, but after I installed the 3TB HDD inside my computer over SATA 3, I found that the System doesn't recognize the format on the drive and I get a notification that the dive is unformatted and I need to format the drive. And this is how it looks in Disk Management:
It seems like there is a special formatting on the drive (I guess related to the 2.2+TB drive problem and GPT paritioning???) that it's SATA 3 to USB controller is also meant to understand and manage... but I don't have enough knowledge to understand what happens behind the scenes.... If I replace the HDD in it's case and use it's SATA 3 to USB 3.0 controller and connect it over usb, I get access to the entire storage space ~2,72TB, and I can see the data stored on it: My biggest concern is what would happen if I install a different HDD (1TB) in this external drive case? I don't want to lose data. Will that controller mess with the partitions of the smaller drive? It's not a problem to format the 3TB drive to use it in the desktop pc, because I havent't stored any data on it, besides it's 500MB of preloaded software. But will it be possible then to acces it using the sata to usb controller if i want to restore the drive back in it's original case?
