I just received my first SATA hdd after years of having my ancient IDE. Anyway when i opened the package i notice the jumpers were by default set to the configuration of "Limit to 1.5Gb/s Operation" with no jumpers being "3Gb/s Operation". Is there any reason i should keep it at 1.5? The hdd is a Seagate Barracuda ST3250410AS 250GB. Also im assuming since there was no chart of slave and master settings that settings are done in the BIOS?
