I recently put together a new system with the following specs
P55A-UD3 Board
i7 860 CPU
EVGA 8800 GTS
2x 2GB G.Skill Ripjaw DDR3 1333
2x OCZ 30GB Vertex SSD in RAID 0 as OS drive - Connected to SATA ports 4/5
2x 1TB WD Caviar Black storage drives - Connected to SATA 0/1
Plextor SATA DVD R/RW - Connected to SATA 2
Front Panel eSATA connected to SATA 3
2x WD 1.5TB Green - Connected to GSATA_6/7 Not recognized at all in either IDE or AHCI
PC Power & Cooling 750W Silencer PSU
I installed Windows 7 on the RAID 0 SSD drive, although I did need to use an IDE DVD drive because it would not boot from the SATA DVD I had installed. After installation, I rebooted and hooked up the rest of the drives. All were recognized fine, with the exception of the 2 1.5TB drives connected to the GSATA ports.
Also, possibly related issue is the BIOS is extremely slow to boot. It usually takes 30 seconds to 1 minute for it to even begin to boot Windows, POST, or get into the BIOS settings. This happened with both F4 and F5 BIOS, regardless of the number of drives installed. Once up and running, the system works flawlessly, but getting there seems to take forever sometimes.
Can anyone offer some suggestions? I feel like I've tried everything at this point and I don't know what else to do.
