Here is the situation... im on an Asus P4C800-E Deluxe board... and... i originally have a seagate 80gb sata hard drive... i just recently bought a seagate 200gb sata and want to make that my primary... i dont want to make them into raid configuration, so i plugged both into the Intel controller (SATA1, SATA2 marked on the board)... when i did that, powered up, and checked the bios, the bios doesnt recognize any of the two drives i installed... but... if i unplug one of them and leave one plugged in, it works... but not both plugged in... Much will be appreciated if anyone can give me some suggestions to make it possible for both drives to work at the same time. Thanks in advance.

Though I'm not familiar with that specific board......on my Asus you have to connect one sata drive to the master (sata1) and the other to the slave (sata 3) in order for them to be configured seperately. If you have them both connected to the master ports (sata 1 and 2) the BIOS will see it as a raid array. ASUS P5GD1 P-4 3.4 SOCKET 775 1G Corsaire PC400 ABIT RX600SE 256MB PCI-E

i think your asus board is newer... but my board has four connectors for sata... the two others are the SATA_RAID1 and SATA_RAID2... there were no SATA3 on my board though... any ideas?

I didn't even ask, but have you formatted the new hard drive yet? It won't be recognized if it's not formatted. The drive came with a CD that you must boot from in order to format. As I've read, that mobo has four sata ports, two of which are marked sata raid. You should be connecting to the other two. If that doesn't work, try putting the new drive on one of the sata raid ports and post back. ASUS P5GD1 P-4 3.4 SOCKET 775 1G Corsaire PC400 ABIT RX600SE 256MB PCI-E

i formatted it already... i installed the new one and installed windows on it already...

Then it likely has to be a BIOS setting. Go to the advanced settings tab and look for your host controller. It should be set to IDE mode instead of RAID mode. Also on the main menu you might see IDE configuration. Open that and make sure it is set to configure using Standard IDE mode. Hit F10 to save and exit.
