Ultra DMA 4 keeps dropping

My Plextor 16x will drop from Ultr DMA4 to multi-read DMA 2 at the slighest hint of a disk read error or so it seems.

I know how to un-install, reboot to reset the DMA but is there any way I Can stop it from changing so often?

Always happens when a read error with Fab Platinum…

You might be able to edit the registry as per the instructions at the end/bottom of this Microsoft KB Article [see below “More Information”]: http://support.microsoft.com/kb/817472/

It will make it so that there have to be 6 consecutive CRC errors instead of 6 cumulative, but when reading a disc that’s producing read errors, it may not help much.

I don’t think there is a way to stop the OS from dropping back automatically, though…

Hi rago88. You might want to check your IDE cables. Make sure they are 80 pin and not 40 pin. And just make sure they are still healthy. ~ Mike
