Solved: Slow reading from P-ATA drive on ASUS P5Q SE

I have trouble to get speed on my P-ATA drive (Hitachi Deskstar 160GB, or Maxtor 300 GB) connected to my motherboard P-ATA IDE-channel. Asus support can not help me resolve this, so I rely on this forum now :)

Brief system spec:
ASUS P5Q SE
Kingston 2x1GB memory DDR
SATA drive (for OS) Seagate Barracuda.
Win XP, SP3

The SATA drive works fine, fast and show up in BIOS setting.
The P-ATA DVD-RW Samsung also works fine, for both reading and writing. This is connected as Master.
The P-ATA HDD, slave, however is extremely slow, 1GB file transfer takes 15 minutes at least.
Their is no setting available in BIOS for the P-ATA devices, except for determining boot sequence.
It does not help to disconnect the SATA, or to change to master, or to re-format, or to change to my Maxtor disc.

BTW, I tried to do a clean installation of Windows7 on the P-ATA, which includes doing a format, but the drive was slow through the entire installation process and after 1hr copying files from the DVD, I gave up. So apparantly, even though no OS is installed, the drive is painfully slow.

Anyone who can help me to investigate this further and resolve?

Thanks
JOhan

I would suggest this go to start > right click my computer > Manage > then click device manager > find your Ide controller > right click primary and secondary IDE channel > Properties > and verify that they are in dma mode. If this doesn't work i suggest running a check disk on the drive.

Thanks.
The device was actually in PIO mode. I chose to reinstall controller for the IDE ander after reboot the device was in U-DMA 6. However, strange enough, after a few minutes doing file copy from the HDD, the device was back in PIO "on the fly". So apparently, the device start off well, but enter PIO after a while? Why is this?
