I'm trying to create non-bootable Tier-drive with 120 Gb Kingstone SSD (empty, formated) and 2 TB Seagate HDD (there I hold my games, downloads, etc), but I can't pick this drive in a menu. When I hover the mouse, I see a message: "Can't add this drive to a Tier-drive because it is non-SATA (not supported in this version)" — non-SATA? What? 
But, however, I have no problem with my other HDDs (marked yellow)
How can I fix it? Maybe I should change SATA port on the MB? (asus rog strix b450-f gaming)
PLS HELP!
