determining if DMA is enabled for DVDROM drives
This is a discussion about determining if DMA is enabled for DVDROM drives in the Windows Hardware category; I have a Hitachi GD-2500 IDE DVDROM drive which performs exceedingly poorly in Windows 2000. When playing a dvd with the latest version of PowerDVD, roughly 50% of the frames are dropped and the sound is quite choppy.
I have a Hitachi GD-2500 IDE DVDROM drive which performs exceedingly poorly in Windows 2000. When playing a dvd with the latest version of PowerDVD, roughly 50% of the frames are dropped and the sound is quite choppy. When copying files from the dvd to both ide and scsi hard drives, Win2000 slows considerably (ie. moving the mouse pointer around the screen is no longer remotely smooth). I had similar problems in Win98SE until DMA was enabled. Is there any way to check its status in Win2000? It's missing from both the device manager and computer management, from what I can tell.

go tothe device manager, go to IDE/ATAPI Controllers, double click on a controller, primary, or secondary, in each there is a tab called advanced settings, make sure both devices are set to dma if available, do the same for both, this should enable dma if its available for the drive.
it will also tell you which mode is currently in use.
