Enable dma mode windows 7

Considering the age of the thread and to avoid confusion, if the troubleshooting steps in this thread did not resolve your issue I would recommend creating a new thread so that the community can focus on that thread. Refer to the following link prior to posting a question so that you may provide all the relevant information, for us to help you:. I am trying to enable DMA mode.

I have uninstalled it and reinstalled it. All of my drivers are up to date. I have contacted customer support for my brand of computer and it was no help. I even attempted to edit the registry, but even that did not have the options that this particular person suggested, so I left it alone.

My computer that is 3 years old can encode a dvd to its hard drive 4 times faster than my new laptop and everything on the laptop is more powerful and faster. It has an Intel HM55 chipset.

I just want to enable DMA or atleast increase that transfer speed. Please help. I would like to make sure my hard drives are set to dma. 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. Thanks, but like Jack, I can not get to a screen like you show. How about sending specifics on your computer, is it sata, etc? I did manage to get to a screen where I've been able to change the external performance to "high" or something like that.

I've also changed to Memeo backup software. As a result, the process is going faster, but is still slow. Should have made one change at a time. Unfortunately, this method of determining support is not foolproof. DMA may appear to install successfully, but may have intermittent problems anyway. Any of the following symptoms may or may not indicate a DMA problem:. If any of these problems occur, it does not necessarily mean that you cannot use DMA with your computer.

The following are likely causes of the problems:. According to the ATA standard, cables can be no longer than 18" 0. 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.
