Re: RAID 0 failure with Gigabyte x58A-UD3R
What may had happened is if both arrays were present, the boot partition may had been on the second array (platter drives) I've see this happen before. usually to fix that, use the windows installation DVD to repair the installation with just the SSD array present. That should fix it.
Don't touch the SSD array, leave it as-is and try repairing windows.
to better protect yourself with platter drives if you need all that space (I'm assuming you needed a 4TB partition), I'd get another 2 drives and set them up for RAID10, your board supports it, that would populate all 6 blue ports and guarantee's full fault tolerance. issue with green/blue/red drives is their built in power saver inhibits the drives rom spooling up quickly (together) and then the raid controller will think there is an issue with the drives. you being in RAID0 minimizes this, you would see issues in a RAID1 especially in a RAID5.
Try that and let us know.
