I did quite a bit of research this weekend on my DS3 board and its bios settings. During my research I read that the SATA ports I plugged the drive and subsequently installed Win XP on does not support AHCI and stuff like NCQ. I also found out I needed to connect the HD to the purple connectors and somehow manually install the JMicron driver when installing windows. From what I gathered you cannot simply switch from IDE or whatever its called mode over to AHCI. In any case, is there enough performance difference to warrant reinstalling my OS? I finally got everthing over to my new PC and would prefer not to go though this long process again. But if its worth it, I will. Let me know.
