I've noticed a decreased performance of my hdd (seagate barracuda 7200.11 500GB Firmware SD1A) in windows 7, extracting and copying files takes longer than in vista. I'm assuming it is a win 7 /driver problem since yesterday it was running fine on vista. Also it is a lot quieter. I have installed the latest intel_inf without succes. The hdd is running in AHCI mode.
