For anyone (or my self in the future) who runs in to this, I also had this problem and tested through a bunch of config parameters but finally got my 4TB "raw" hard disk to show up correctly in SR, seemingly even with SMART.
Important for me was to use version 9 of the "Machine", add the disk as IDE (even though it´s physically a SATA drive) and use the LSI scsi controller.
