    Unrelatyed to an answer, but are you sure it is hardware RAID? It looks like SB950 is software RAID. (Or to be more precise, fake RAID just like the Intel chipsets do. No real dedicated RAID hardware, only support in the firmware (UEFI or BIOS) and all the work done in drivers. This is relevant as to where to look for the problem. With HW RAID the RAID card should present only one drive. Problems should be handled by the RAID card. FOr software RAID it is handled by windows.

  • Well I will just explain how I installed it. I thought it was a hardware RAID, but you may be right. I reinstalled Windows and at the beginning installed the RAID drivers that I downloaded from Gigabyte's website. I set up the array in a new BIOS utility that was accessible right after the bios boot up screen. Windows only ever sees one drive (my F drive). Is this considered hardware or software RAID?

  • Also updated my post. I am running the mirroring RAID, not the striping RAID. Sorry for the confusion.

  • Ugh. Loosing data to a mirror sounds more serious. Is there anything in the log files ([start] [run] eventvwr.msc) ?

  • A little background about RAID. In the past CPUs were relative slow compared to disk IO. Creating a RAID array consumed significant CPU cycles, which where then not available for other tasks. One solution for this was a dedicated card with its own CPU (or custom ASIC) to do these calculations. This was mostly done for RAID 5 and similar. (RAID 0 and RAID 1 are trivial calculations). Back then you either used software RAID (the OS/driver did it for you) or hardware RAID (multiple drives connected to on plugin card, that card presented one [fake, larger] drive.
