I have some 4T SATA drives in GPT, they only be detected as 2T drive under Windows server 2016, but they all be seen as full capacity = 4T under FreeNAS.
All the hardware configuration is the same, drives are connected to SATA Ports. Difference is OS only.
I am not sure if this is an issue with SATA controller or an issue with drive itself. I have tried 3 party utilities, reset the drives, convert to GPT and so on, the issue remains the same. Windows wont see the full capacity of those drives.
Anyone had similar issue before?
