Welcome to Tom's Forum!
Yes, just move it to a SATA2 port. Preferably the first SATA2 port if its the boot HDD. There's no advantage for a mechanical HDD to run on a SATA3 port. The SATA2 is 300 MB/s ports and the HDD at best is 140~150 MB/s. Oddly it's the maximum speed of the original SATAI 150 MB/s.
Further, if you have it set as AHCI then go into the BIOS and Set the Intel SATA2 -> AHCI.
Verify by checking the registry -> http://support.microsoft.com/kb/922976
or you can run Fix It.
