So these drives are 520b sector? I don't have good experience with an Ebay seller from Germany selling me 2x 2TB Seagate DKS2C-H2R0SS by givning me false information. He stated it was ST32000444SS, but it wasn't. Tried to format them using sg_utils, it went fine, but even with 512b sector, CentOS 7 refuses to accept them. Fdisk nor parted can detect these drives.
Dmesg reported the following:

Googling reveals these could have been NetApp disks hence some weird FW issue perhaps.
Just me paying €200 as these were "new"
I'll omit buying 520b disks in the future.
Sorry, if totally OT here.
