I should add that I formatted the drive as NTFS.
I also tried the connecting the drive as GPT (1 volume, 3TB) to my Synology 916+ and it detected the drive just fine.
Since RN102 detects the drive when formated as MBR I think this is software issue.

It could be. There are some fixes in 6.6.1 beta for USB drive detection.

Hopefully 6.6.1 will adress this issue.
The drive was manufactured on october 2016 and is a Buffalo HD-PNF3.0U3-GBD. (Released in january 2016)
