What happened was that I have a mirror RAID (RAID-1) and one of the drives died.

As far as I know, one should always use identical drives for mirror RAID (don't mix iszes, don't mix manufacturers, right?), but I can't afford 2 right now, so I bought a new Hitachi 2tB to match my old Hitachi 2tB - the difference being that the old one is SATA 2 and the new one is SATA 3.

The J-micron RAID controller does not see the new drive ... can it be that the MSI P35 Neo3 motherboard does not support SATA 3?

Or is it something else?

Interface-wise, the SATA-3 should be backward compatible, but I suspect that maybe your RAID controller is being particular due to the firmware. Try taking out the SATA-2 drive and seeing if you can get the controller to recognize only the SATA-3 drive. If so, you know your answer. If not, try it in non-RAID mode, or if you have another system, try the SATA-3 drive there to make sure it was not just DOA. If this works, please post back and I will move it to the answers so you could mark it. – KCotreau Jul 9 '11 at 12:13

What is the exact model of the drive. There may be a jumper on it. – KCotreau Jul 9 '11 at 13:03

I could not find that model, and it is usually a lot longer for most manufacturers. Look at the top of the drive if you have not already...it should be printed there. – KCotreau Jul 9 '11 at 13:26

That is it. This has all the docs for your drive, so you might want to keep this page: hitachigst.com/tech/techlib.nsf/products/Deskstar_7K3000 This is the Install guide, which I am looking at now: hitachigst.com/tech/techlib.nsf/techdocs/… I see nothing about a jumper as on some of these drives have for compatibility. At this point, I would call Hitachi and ask them, and also see if they have a firmware update for one, or both drives. – KCotreau Jul 10 '11 at 1:11

Thanks very much for all of your help. I still suspect that the motherboard or J_micron raid controller on it cannot support SATA 3\ :-( – Mawg Jul 10 '11 at 3:18

@Mawg You may well be right, but at least if you ask about the firmware, you will be able to rule out the only other thing it probably could be. – KCotreau Jul 10 '11 at 3:23
    
+1 KK. I will try manufacturers and also ask at a shop that I trust. Thansk again for all of your help – Mawg Jul 10 '11 at 3:46
