I recently did a major upgrade on my old home PC in stages: power supply a couple of months ago, new motherboard/CPU several weeks ago, and a new Caviar Black 500Gb SATA-3 drive yesterday (Fri, 1/21). According to a utility I have, HD Tune, my drive is transferring at the old PATA data rate, around 132 Mbps. This is working okay with the OnChip SATA type in the BIOS set to “Native IDE”. I tried setting the OnChip SATA type to AHCI thinking it would let the drive transfer at the SATA-3 speed, but the machine hangs on boot. System is Win XP Pro.
This is my first experience with newer technology, after using an eight year old mother board and CPU with a PATA drive setup, so I’m not saying I understand it all. Am I missing something, or do I expect something to happen that’s not going to happen? I want to get all the performance from the system that it’s capable of giving.
Enlighten me, please!
