I have an auto detect bios and i am attempting to add an additional hard drive to my desktop. I purchased a seagate to go along with my current WD one. When I connect the new drive alongside my current one the BIOS will not detect it. I know the power cord/sata cord/sata plug all work because when I connect ONLY the new HDD it is detected. Thanks in advance for any help!

Hi there,
Try reseting your bios, this will reset all your current bios settings.
If you motherboard is new it may have a "Clear CMOS" at the back, use a pen or something and hold that down whilst the computer is on and running and see if that helps.
If you haven't got a "Clear CMOS" button go into the bios and browse around for a "reset bios" button.
Hope this helps

The only option i saw in BIOS was "reset defaults" which I did to no avail.

Ken~ It does boot when both are connected, I cannot see it in disk manager and i have tried switching it to a different sata port, again, to no avail.
 
One suggestion from Microsoft is to try the diskpart command to see if the drive shows up.
"1. Type diskpart, and then press ENTER to open the diskpart tool.

2. Type list disk, and then press ENTER. A list of available hard disks is displayed.

3. Type select disk=[n]

n specifies the disk number of the disk to receive focus.

4. Type list partition

This command displays the partitions listed in the partition table of the current disk.
5. Type select partition=[d]

This command selects the specified partition and gives it focus.

d specifies the drive letter or mount point path of the partition to receive the focus.

6. Type format drive: /fs:ntfs /quick

For details on the commands, refer A Description of the Diskpart Command-Line Utility

I'm not sure whether or not this will help - http://knowledge.seagate.com/articles/en_US/FAQ/168595en - but it may be worth a read. It address a drive not showing up in the BIOS. The trick here is whether or not the drive needs to enabled in the BIOS. Since yours is set to automatically detect drives this may not apply.

Have you checked to see if a BIOS update is available?

I have continued research and have found nothing encouraging towards a solution. Should i go ahead and do an RMA? is it even possible its a problem with the drive since it DOES detect when it's connected on its own?
 
You could go ahead and RMA the drive and a new one would tell you if the problem is the drive or something else. If you have an external drive enclosure or a cable to connect the drive externally (SATA to USB) you could try that first and see if both drives are recognized and that could eliminate the drive as the problem or confirm it is the problem. If the drive fails as an external drive then you should RMA it.

I would have to purchase the equipment to test the drive externally, not sure if that would be worth the effort. Its just always so discouraging when hardware does not work as it is intended.
