I have a problem with my Plextor PX-716SA, or rather the windows installation. I have two windows partitions on the same machine, where I use my PX-716SA. One of the windows installations shows a problem, in that writing causes very high CPU load and low write speed. On the other partition all is working fine.
Asus A8V deluxe
PX716SA on the VIA SATA controller.
VIA drivers installed
I tried repairing windows and reinstalling the VIA drivers. To me it seems like it would be a DMS/PIO issue, but I can't find a way to change any such setting for the PX-716SA.
Here are two performance measurments one showing the low speed with high cpu load,and the other is the working windows installation.
Anyone have an idea on what to do? I know I can re-install windows, but i'd really like to avoid that - boring and time consuming...
