RAID issues

Hello.  While I am waiting for someone from tech support to contact me, I thought I'd post my RAID issue here and hope for some help.

While on my DS gaming PC the other night my screen froze and I was booted out of the game - then my PC blue screened.  When I rebooted, the message that normally says RAID 950GB Healthy - was red and it did not say healthy. Said RAID failed.

The strange thing is that when I started looking into the connections for loose cables, etc...it made no sense to me.  I know that one of three things must be wrong...either bad drive, bad controller or bad cable but how do I pinpoint the culprit here?  How do I verify the system still has or knows about the RAID?

When I look in the BIOS, it only shows one drive.  I have a single drive for my OS and a RAID 0 for my games.  The OS drive shows up in the BIOS and is fine.  The RAID drives are gone.  After messing with the cables, etc., the raid message went away completely and now a message blips on the screen that says Detecting raid....No drive dedicated for raid....raid disabled.

When I look at the cabling, here is what I see (and it doesn't make any sense to me).  Lets call my drives Drive A - the single OS drive, B & C - the RAID 0 drives.

I see a normal power connector plugged into Drive A and a SATA cable plugged in to Drive A that runs to the motherboard SATA socket.  I have replaced this cable and it made no difference.  Drives B and C only have what looks like some differnt type of power cable (thin, wide, flat black cable) connecting them together and to the power supply.  Both had SATA cables plugged into them but the other end of the SATA cables weren't plugged into anything...?  Shouldn't they have SATA connections to somewhere?

The one thing I know for a fact is that there are 4 SATA sockets on my MB and there has only ever been one SATA cable connected.  the other 3 SATA sockets have always been empty.  The raid has always worked until this failure a couple days ago.

Help me please!  :-)  It is very frustrating not knowing what the issue is and how to go about troubleshooting it.  Is it possible that something has been corrupted?  How do I tell?

If this is a failed HD- I would like to disable the RAID and just use the good drive for now.  Not even sure how to do this- but it is a last resort only after I can prove the HD is bad.

Any help is greatly appreciated.

Thanks.
