I formatted disk9 and then I replaced disk1. I rebooted and let the system go through a full parity check and everything is now back to normal.

Yes, the new controller is a Pcie controller

This is the latest Diag. New controller card in place,

The original disc1 is still in place in the array as disc1

Not using VM's, cables are not bundled, I did try resetting the marvel controllers, I have ordered 1 non-marvel controller in case that has something to do with it. Connectors are on solid and have plenty of slack. I am not sure what VT-d is. Should I just remove the 2 drives that are showing unmountable?

I am considering this power supply. Thermaltake Toughpower GF1 850W 80+ Gold SLI/Crossfire Ready Ultra Quiet 140mm Hydraulic Bearing Smart Zero Fan Full Modular Power Supply 10 Year Warranty PS-TPD-0850FNFAGU-1 Opinions?

I checked both sata cables and power cables for all the HDD's. Restarted and the same 2 disc are showing unmountable again. Main page shows parity not valid, dashboard shows parity valid. Diagnostics attached. tower-diagnostics-20220809-1956.zip
