HBA showing 8 disks when only has 4

Recommended Posts



I have 3x "StarTech.com 4 Port PCI Express 2.0 SATA III 6Gbps RAID Controller Card with HyperDuo SSD Tiering - PCIe SATA 3 Controller Adapter"

Amazon Link: https://www.amazon.co.uk/gp/product/B00BUC3N74/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1


After I have updated the synoinfo files to let me use all these there appear to be a batch of 4 disks after each card that show up but cannot be used.




Why are these blank spaces showing?


Ports 1-6 = Motherboard

7-10 = First PCI HBA

11-14 = Always empty

15-18 = Second PCI HBA

19-22 = Always empty

The issue this causes me is that I have a single RAID 6 which contains all theses disks, (11 disks) when I upgrade the synoinfo file resets back to 12 disks so only 11 of my disks are on this.
