Hello,
I just plugged a hard drive into one of the secondary (Marvell) SATA slots of my DZ77GA-70k board and booted into the BIOS. I observed all of my other drives plugged into the Intel SATA ports, and I also observed the secondary SATA controller check box checked as operational, but I didn't see any devices listed there. Continuing to boot into the OS, of course the drive was invisible there as well.
I've confirmed that it's not the drive by swapping sata cables with another drive that had been plugged into an intel SATA port -- when I did that, the new drive appeared and the old one disappeared. I've also tried several different cables.
Any tips or guidance would be greatly appreciated.
