First set of SATA working fine, second set broken? MSI 875P-Neo FIS2R

Hello. I just bought a 500gb drive for my computer and I've run into a bit of a problem.

I have 2 80gb drives running RAID0 on my MSI 875P-Neo FIS2R and it worked fine through the 1st and 2nd SATA connections.

I plugged in my new 500gb drive to the 3rd (and then tried 4th) SATA and no luck, it wouldn't recognize the drive.

To troubleshoot, I plugged in my working RAID0 array into the 3rd and 4th SATA and it wouldn't recognize those either.

I have concluded that either the 3rd and 4th SATA connections on my computer are broken, or they are somehow disabled and I don't know how to activate them. I took a peek in BIOS at the ATA configurations and couldn't find anything that would totally disable the 2nd set of SATA

Any help? I hope my board isn't broken because the warranty is up for sure by now

Thanks for your time

Check in your bios under Integrated Peripherals->On-chip IDE and see what the settings are. (And post them here if you need more help )

I've been trying to tinker around with them to get my 500gb drive to work, but no luck yet. Here are the current settings that work for me:

On-Chip ATA(s) Operate Mode - Native Mode
ATA Configuration - S-ATA Only
P-ATA Keep Enabled - Yes
P-ATA Channel Selection - Both
S-ATA Ports Definition - P0-1st/P1-2nd
Configure S-ATA as RAID - Yes

Thanks for your time, if I can't get this to work in the next few days I'm shipping it back to newegg
