I've got a RAID0 array that intermittently fails on a new DVR. Sometimes it fails, sometimes it boots up fine.

I thought that maybe it was a cable, because when I unplug and replug them, it generally boots up.

But the weird thing is, CrystalDiskInfo shows only one drive, where there are actually three. I ran CDI on another DVR we have deployed at another location, and that one shows three.

I'm using a Gigabyte GA-Z87X-UD5H Z87 LGA 1150 motherboard the built-in with Intel RAID controller. 3x Seagate Barracuda 1TB hard drives. Windows 7 Pro.

I don't really trust Seagate, could it be one of the hard drives?

Seagate has nothing to do with it. You should NEVER use RAID 0 as primary storage like this.
That's just begging for data loss.

It's very likely that you've got an unstable drive, but that is to be expected because drives all fail eventually, some earlier than others.

If you've got a backup, or you're not backing up this data or don't need what's there now, run Seatools to identify which drive(s) is unstable and replace it.

RAID0 really needs TLER (Time Limited Error Recovery) drives for reliable operation; these are expensive, enterprise-class drives. If there is a boot delay option in the BIOS, add at least 3-5 extra seconds for all drives to spin up and be ready for the initial access on boot.

You can also use "NAS" drives with TLER and Enterprise UBE ratings, though TLER won't help you if you've got an unstable drive either way.
Enterprise drives would probably be overkill for a small DVR system like this.
