primary ide switches to p10 mode

[black.belt]

I always had the primary for my hard drive at dma 5.
I tried installing sony dvd burner and found they were not compatible and while i was doing this was the first time it changed to p10.
I thought it was the ribbon cable as i straightened the kinks and restarted and it went back to dma5.
I then found the pioneer was compatible and burned at least 20 dvd discs.
After that I noticed it very slow at reading and writing and noticed the primary ide was back to p10.
I changed the ribbon cable but it did not make a difference.
I eventually got it to work by uninstalling the primary ide controller item in the device manager.
Now after a week or so it has reverted back to p10.
I now know straight away as it takes ages to boot the pc up
WIN xp,
pioneer 106,
alcohol 120
nero 6
etc.
Any ideas as it is becoming a pain in the butt.

cheers

Windows switches automatically back to PIO if transmission errors occurring;
only way to go back to UDMA is the way you already tried (removing/fresh detecting);

i would recommend you to connect your sony dvd burner via 40 wire cable as master at the secondary controller;

Sony DVD burners work fine as Ultra DMA 2 devices (not more than that, but this also applies for all Atapi devices I know of). Your busmaster drivers, or a crosstalk enabled (AKA 80-wire) cable might be the reason. In certain systems packet writers like inCD or DLA or DirectCD have serious issues with applications like the VIA drivers or Intel Application Accelerator, either don't use the above applications or install just the OS busmaster drivers, and hook your devices via old 40-wire cables.

i think i have confused everybody

i was trying to install the sonys as master on the secondary but they didnt work and i returned them.
the pioneer works and i have installed it on the secondary as the master drive.
I do have incd and I will uninstall it as i dont need it.
Thanks for the replies.
