It is (AIUI) a mandatory part of the SATA spec that ports will negotiate with the other end of the link and settle on a mutually acceptable speed - thus the 6G port should automatically settle at 3G with the older drive. If the BIOS/EFI firmware doesn't setup the hardware properly, then the board as a whole is faulty.

As I said in my other reply, the mobo is fine.  I am very happy with the 
Asus mobos in general; I have 3 of them now; two in 24/7 service for 5 
or 6 years.  In fact the Z87-V Pro is a great backend mobo with 8 SATA 
ports.

The SATA implementation on some drives is broken.  Specifically, in my 
case, the Seagate ST1500DL003 1.5TB drives don't negotiate the speed 
correctly.  Of course, I have 3 of them....  The other Seagate, Hitachi, 
and Samsung drives work fine.
