did anyone have problem using k50 with windows xp? hardware interrupt shows 50% processor utilization when writing large files(copy from network). i suspect the hdd is running in PIO mode and not DMA mode. i suspect this is because in order to install windows xp, one have to set hdd native ide in bios instead of sata.

did anyone notice this problem? what about in vista, linux and windows 7? i believe this is not a problem since you can enable sata.

thanks.
