OK, here are the challenges. AMD hasn't released RAIDXpert for 8xx series yet. HDDErase does not work on this board regardless of mode (SATA3, SATA2, AHCI, IDE) or controller (SB850, JMicron). There is no other way to reset Gen 1 x-18/25 on this board except PerfectDisk+AS_Cleaner.

Just installed OS on my third drive and going to bench SSDs in single mode and see what the hell is going on with SB850.
