Whats wrong with my dma in win2000?

[BD2003]

I get DMA just fine on my secondary so thats no prob. But its the primary thats the prob. I have two hard drives on it, one 30gb, one 13, both support ata/66. I used to get UDMA on them, but it doesnt show it in win2k anymore. I dont get ATA66 or any DMA for that matter, just crappy pio mode. My HD scores are truely pathetic because of this. Abit Kt7, via 4.29 final. Theyre attached using a ATA66 cable. Everything is set correctly in bios. As far as I can tell I've done everything right, and it used to work before, but doesnt anymore. Anyone have any ideas?

Go into Device Manager and find the Primary and Secondary IDE Controllers.... go into properties and you need to turn on DMA... there are 2 choices for master and slave... PIO Only or DMA if available.

Thats been done already. Its not a rookie question of how to do it, it just doesnt seem to be working properly.

There is a known bug in Windows 2000 which effects this. A fix is supposed to be included in service Pack 2 which is due out later this month

what benchmarks are you using?

Have you tried reverting back to the 4.24 4-in-1's ?

I am using the 4in1 4.29's and it works fine on mine. The difference may be that I did a fresh install, 4.29's, then SP1. Maybe they have bundled the hotfix into the SP1 now?

Do a search here for &quot;hotfix&quot; and give it a try. I would have assumed that via would have bundled it in the 4in1's by now though.

Try uninstalling the ATAPI support in the 4in1's if that does not work.

I have RAID-0 running on my system. I am not sure if RAID users are having the same problems as the non-RAID anyway.

Good luck.

I've always had trouble since day 1 with dma66. But dma66 isnt much of an improvment over dma33. As long as its DMA at all, its good. Just switched my cable back to an ata/33 cable, and everything works great.
