Is it possible to force a HDD to usa UDMA mode and never PIO?
I'm having a tough CPU usage when I try to copy something to a 80GB SATA hard drive, on SATA port 1.
I already tried uninstalling the drive through device manager and I still have the problem, I also tried to uninstall the "Main IDE channel" (Or whatever it reads in english) and it's still fu'd up.
I had this problem months ago with another motherboard and the solution was to uninstall the "Main IDE channel" and the HDD at the same time and then reboot.
here's a pic of that "Main IDE channel"
On the properties of that I noticed the transfer mode is PIO and not UDMA at it should be.
I thought the problem could be the HDD itself but no, it's ok.
Then I thought it could be the SATA port, but I tested it with a Linux distro (Chakra 2012 Archimedes) and copied a heavy folder (Like 16GB) and the transfer rate was ok. Then there's something wrong with the drivers, I believe.
I'm using WindowsXP Professional 32-Bit Service Pack 3.
My mother board is a ASRock P4VM8 (Socket-478), here's a pic
So, finally, how do I force the hard drive to use UDMA and never PIO?
