I dont know if this is an issue from my RAM tinkering or is it another bug in the platform...
I had this exact same behavior on my Prime. Have a Samsung 840 EVO on SATA0, two identical WD Black 2.0TB on SATA1 and SATA2, and BD-RW on SATA3; SATA0 is not recognized more than half the time. I had to plug it in SATA4 and it is now always detected..
I had read somewhere that it may be related to how the SATA specs do it things on detecting SATA0 and 1.
I'm using AHCI and software RAID for SATA1 and SATA2, CPU-Z hanged when using Firmware RAID + AMD RAID Driver; it was hanging with HDD Guardian too.
