Welcome to cdfreaks.
I’m not that familiar with latest nVidia mobos but will give it a shot anyway.
You said you tested all SATA connectors, I think there is a SiI3112 controller installed with an internal connector (black?) at top of mobo.
Are all drivers installed, this also for the SiI controller? And bios option for SiI, by default its set to RAID mode I think.
Without knowing your BIOS settings for all SATA controllers/ports and what other opticals/HDD’s you run its almost impossible to advice more.
Read mobos manual, maybe that will guide you further.
The error seems to be well documented with pioneer drives…
Well, I’ve not seen that many posts about this error in our Pioneer forum anyway.
[I]BTW,[/I] there must be hundreds of members here having the same mobo. Give it some time and I’m sure you’ll get more suggestions.
