RAID failure - system won't boot

[ocs]

I'm relatively new to this, so any help would be greatly appreciated. I built this rig a few years ago and I haven't had any problems. Everything was working fine yesterday, but today I turned on my computer and it won't boot up. I get the following message:

Reboot and Select proper boot device
or Insert Boot Media in selected Boot device and press a key

I have 3 hard drives:
HD // 2 Seagate Barracuda 500GB ES.2 7200 RPM SATA (RAID 0)
Model: ST3500320NS
HD2 // 1 Seagate Barracuda 500GB 7200.12 RPM SATA
Model: ST3500410AS

Bios:
Storage Information: Configure SATA as RAID
Boot device priority: 1st Boot device: RAID: ST3500410AS
2nd Boot device: disabled

Intel Matrix Storage Manager Option ROM utility:
RAID Volume:
ID: 0 Name: hd0 Level: RAID0(Stripe) Strip: 128KB Size: 931.5GB
Status: Failed Bootable: No

Physical Disks:
Port: 1 Drive Model: ST3500410AS Serial#: 5VM0ADHS Size: 465.7GB
Type/Status: Non-RAID Disk

Port: 2 Drive Model: ST3500320NS Serial#: 9QM8E507 Size: 465.7GB
Type/Status: Member Disk(0)

On POST, it says no hard disk is detected

I really hope that one of my hard drives is not fried. I recently did a cleaning, but everything has been working fine in the couple of days since then.

Not really sure how to proceed. How can I determine if one of my hard drives is damaged? How can I tell which one is damaged? I'm trying to figure out where Windows is installed, but I'm not really sure.

Thanks a lot for your help!!!!

It looks like you were booting off the raid 0 set, and one of those drives failed.

You can create a bootable drive test to check the drives, but you will need a working Windows machine to do so.

That's what I was afraid of.

Thanks a lot for the link!!! I will do that right now and report back.

I'm pretty sure one of the drives that was configured in RAID 0 is shot. I switched around the power cables and the SATA cables and it is always 1 drive that doesn't show up. When it's running, there is also a slight clicking sound.

So, can someone give me some suggestions as to how to proceed. Do I just have to clean the working RAID drive, buy 1 more and configure the RAID again. Should I purchase 2 new drives if I want to do the RAID 0 again? Any suggestions on how to configure the drives next time.

Thanks a lot for your help
