Only 1 HDD recognized by bios

First, here's my setup:
Asus Sabertooth 55i motherboard
Intel i5 Lynnfield processor (4 cores @ 2.8ghz)
12gb RAM (1600mhz, DDR3)
ATI Radeon HD6770 (1gb)
128gb Adata SSD main drive
500gb Seagate storage (previously main drive)

Last night I unplugged the HDD, installed the SSD, then installed Windows 7 Ultimate 64-bit. The install went smoothly (and FAST!) and I was able to boot into Windows without problem. When I plugged the HDD back in, only the SSD was recognized in the bios boot order and when I get into Windows, the HDD is not recognized. If I unplug the SSD, the opposite is true... I'm not quite sure where to go from here, but I'm getting the feeling it's something stupid and small that I've missed. Any ideas?

Is it recognized in disc management?

 

[daswede1127]

Nope, not recognized in disc management at all.

Did you recheck the connections.

 

[daswede1127]

Yeah, I made sure they're properly seated.

Do you have another sata connection to try it on?

 

[daswede1127]

I didn't really think of it until now, but could it be because the SSD is plugged into the SATA_01 on the jMicron controller (used for Drive Xpert and/or Super Speed features) and the HDD SATA_02?

Might be.
