Vista - Vista x64 SATA Burner issues

I have two SATA burners installed with Vista x64, they burn fine but burst rate is only 14 mb/s when it was 60 mb/s on XP Pro

Does anyone know what driver I might have installed that I shouldn't have or need to install?

This is a Asus P5K Deluxe P35 chipset board.


Thanks

the first thing I'd check is if there is a firmware update for your drives...

Drives have the latest firmware that I sure of.

I am still running 0404 bios because it is stable, may try 0705, not sure what I am going to do.

thanks for the reply

Well I tried putting the DVd drive on all the different ports and still I am only getting 30 mb/s (sorry said 14 mb/s before).

This is not right, I am thinking it is a driver problem.

Anyone with a P5k Deluxe and a SATA burner want to try something for me?

Download CDspeed (it's free and no install needed) Nero CD-DVD Speed website

Then put in a already burned DVD, select your drive in the drop down list, click "Run Test" and select "Burst Rate", it only takes a few second.

I really would appreciate it.

Then list what drive and what what motherboard BIOS you are using.

edit: I have tried this drive in Vista x86 and get 60 mb/s so I know it's Vista x64 related and really think it's driver related at this point.

I'll do that for you this evening when I get home.

Thanks Scott,

I did flash to 0705 and while no problems it didn't fix it

Anyone using a SATA PCI card with Vista x64 support?

Well I still have the problem, checked my "2" IDE drives and they are also maxing out at 30 mb/s and this is not right.

I have tried new cables and different SATA ports, still nothing.

I think I have it narrowed down to something I have installed, I will be gone for a few days so I won't start uninstalling programs yet.

Only programs I can think of that access the Burners are AnyDVD, Nero and PowerDVD.

If anyone else has the same motherboard and Vista x64 and would take 10 mins to run the test in post #4 I would appreciate it.


thanks

Did you include the SATA drivers during Vista install? If you don't change the BIOS options, most mobos will use IDE emulation for SATA drives (much slower, but it doesn't require driver installs during vista setup).

My GA-G33M-DS2R Gigabyte mobo was like that- I had to change it from "IDE" to "ACPI" For SATA mode in the BIOS.

If you're up and running, and you didn't install the SATA driver from the CD or on ASUS site by pressing F6 during vista setup (and subsequent loading via floppy/cd/dvd/flash memory), you're probably in the IDE emu mode. It made a huge difference for me.

I didn't, so how can you change it?

Let me guess reinstall?

Thanks
