Drives not showing up

Forgive me for my ignorance this is my first go at setting up raids.

So I have a HP z800 it has 2 x 500gb evo ssds, 6 x wd blue 750gb 2.5 disks in an icy dock and 2 x fusion iofx 420gb pcie drives. I would like to set up a RAID 5 or 10 on the 6 wd blue’s for and a raid 0 on the fusion io’s and leave the two ssds as is for system and applications. Ive tried following the guide to use intel matrix storage manager to set up the raids but it only recognises the two ssds, any ideas on how to fix this or setup raids another way?

thanks

Marc

@ spill:
Welcome at Win-RAID Forum!

Are you sure, that the HDDs are connected to Intel SATA ports?
The Intel RAID Utility is only able to create a RAID array with drives, which are connected to Intel SATA ports.
Have you already tried to unplug the SSDs while trying to crate the RAID array?
