Hi,

I have two Samsung Evo 840's plugged in to my ASRock H97 Fatal1ty Performance motherboard. The BIOS recognizes both, but when Windows 8.1 Pro is running, it will only ever see one of the drives in Disk Management. Both drives are formatted NTFS. If I put in a Sandisk Extreme II in place of one of the Evo's Windows sees both, no problems. Any ideas?

Here is where it gets interesting... I moved all the drives over to an old Gigabyte motherboard. When it was all set up, I could see both Samsung drives... so maybe this is an ASRock thing?
