Disable dma setting in windows 7

I've done a search and understand the various procedutes using Device Manager, etc. However, I do not get the same screens that the various instructions say should be there.

No where is dma mentioned. I've checked this very closely, could be doing something wrong, but I don't think so. My computer is an xps running Windows 7.

I've also checked settings on a brand new Inspirion laptop and the settings are the same -- no mention of dma. I'm afraid you will need to look elsewhere for the cause of your problem. If you are using DVD's, have you tried another brand? This is obviously incorrect because even the slowest Serial ATA mode 1. Mueller is an author I have trusted for quite a while, but I'm always willing to re-learn something found to be in error.

These long cables may not work reliably, if at all, with high-speed DMA modes. Cables also vary greatly in quality. When you're installing a hard drive, always replace the old ATA cable with the cable that comes with the drive. If no cable came with the drive, buy a good-quality DMA cable separately. If you have problems with DMA, replacing the cable with a better cable may solve them. If you reconfigure an older drive to use DMA, first check the manufacturer's web site for details on that model.

Software patches for some models are available. You don't need to configure settings manually. If the SATA drive is running at all, you can be sure that it's using optimum settings.
