This is my first post on this site, and I am not particularly technologically minded, so straight off let me apologise in advance for any stupid questions/foolish errors that I will make! Please bear with me!
My problem is to do with a new DVD drive I have installed. My computer is a Dell Dimension 5150 and it has 2 DVD/CD drives, for which I had been using one to rip information and the second to burn it to a new dvd. One of the drives stopped working recently so I bought a Lite-On DH-20A4H DVD RW RAM drive to replace it. I took out the old drive and put the new one in myself. My problem now is that it takes far longer to burn a new dvd, whereas with the old drives it took about 20 minutes.
I searched this site for some answers and found some information about DMA mode and PIO mode, and how PIO is much slower. I checked my device manager and, sure enough, windows has switched me to PIO. I followed all the prompts on this site to switch it back to DMA, but every time I try to burn a disk it switches it back to PIO. The first 4 or 5 minutes it burns really quickly, like it used to, then it slows down and when I check it has gone to PIO.
I have tried a few things. I have switched the DVD drives around to see if that helps, but no. I have uninstalled the Primary IDE channel and then rebooted for windows to try and install it again, but the same thing happens. It starts out on DMA but switches to PIO after about 4 minutes.
I have even followed a thread which talked about typing regedit into the run box, but to be honest I didn’t really understand what to do on this, so couldn’t follow it through.
Does anybody have any advice as to how I can get my computer back to DMA for good, so that burning DVD’s does not take hours on end?
