SSD + HDD not showing up (bios or disk management)

[annisnaeem]

Hi guys,
I've been researching the last week every thread I could find here on this subject. I looked through various things and I just can't come up with an answer. I found the amazingly nice and detailed WyomingKnott's thread, and went through it step by step repeatedly to no avail.
So now I turn to you nice folks, and hope I can get this to work .

My problem is that I cannot see my attached hard drives in my disk management utility. I do, however, see them at startup for a few seconds. But not in my BIOS. Which is odd.
Here is what I see on startup proving that my computer does recognize them at some point:

I pressed CTRL-M and went into the initialize directory. It shows them there as "Ready", and a message appears saying to the extent of: "there's nothing more to do. restart"

From what I understand through research, my motherboard might have a controller on board that is preventing it from being seen in disk management? I'm a novice with this stuff so here is where I am lost.

The two drives I cannot see in disk management/upon booting up into windows:
-Crucial MX 100 (500 GB SSD)
-Western Digital HDD - 4 TB

My system details:
-motherboard: SUPERMICRO X8DA3-O Dual LGA 1366 Intel 5520 Extended ATX Dual Intel Xeon 5500 series
-Windows 7 Professional 64 bit
-X300 intel workstation

Thank you so much in advance. I really appreciate it!

Are your fans running in your PC, check them all. Check that your HDD's are running, like you can physically hear them moving. Make sure all cables are plugged in (Im sure you have, but it's better to ask now than later)

DaronMal> Thanks for the quick reply. Yes to all of the above.

What about trying to unplug the nonworking hard drives, see what it does, let it fully boot and use it, then shut down, plug them back in.

Your RAID controller is picking up the drives - so only within the RAID controller BIOS will you actually "see" the individual drives. The standard mobo BIOS will only see the RAID controller.

Thanks for the quick answers guys.
This is weird that as soon as I posted this, I tried one last thing which was to press CTRL-M, go into the RAID settings, find each drive and click "add configuration", set them up as RAID's (even though that's not what I was trying to do), then go into my disk management and format them as Simple Partitions.

That brought the hard drives online. And ronintexas, you are correct. The RAID controller was seeing them, and I had to go through that to be able to see them later in my OS.

Thanks for the quick replies! I hope this helps someone if they are having the same problem.
