issues with my DMA modes on vista 64 bit ultimate

well basicaly 1 of my CD DVD burners that is brand new will not read or write corectly and im almost positive its cuz its set to a Ultra DMA mode that is to high (ultra DMA Mode 6 )
my first CD/DVD burner/drive is a Benq DQ 60 which is set to UDMA 5 and it works fine

the new CD DVD Burmer/Drve is a LiteOn 22x internal sata DVD CD writer and is set to UDMA 6 and will not read disks and when it does it runns so fast that the Game or program will get stuck ,it needs to be changed to UDMA 5 like the other but unlike XP you cant change the Mode it runs in so after paying way to much money for this OS i think it should at least give you the options to configure how your ide ata/atapi controllers work
if any one knows how to change these modes or has any info as to if im missing an update or a driver or something please let me know thank you any insight would be greatly appreciated

Can you cange this using your BIOS or a jumper on the CD?
If not let us know.

Not sure you can change the UDMA settings on a SATA drive but you could try this procedure - Troubleshooting: Enabling/Checking DMA in Windows Vista, XP, 2000, Me, 9x - Club CDFreaks - Knowledge is Power.

Official Microsoft - Turn Direct Memory Access (DMA) on or off - Windows Vista Help - Same procedures though.

I have two CD/DVD drives in my system, one SATA, one IDE - with these procedures I can only disable (not change) UDMA on the IDE drive only - not my Lite-On DVD SATA drive. Also, I have my SATA channels set to AHCI in the BIOS, so my options may differ from yours - best seen here. The red dots indicate this is the IDE CD-ROM.




Hopefully this helps.

thanks you both i found that i can change the liteon in the bios and the benq the same but im not sure what to set the lite on to right now i have it st to udma5 and it seems to work but there are like 7 options and i dont know which is the best
the benq dq 60 works great set on udma 5 but thats an ide the liteon is a sata drive and im not sure which setting to put it to if you guys have a good idea i would much appreciate it
thanks for the help you guys are awsome
