Please do not look at the setting but use the next article to set it to PIO and back to DMA. It's easy to do, requires no reboot and very safe.
There is a possibility the drive has failed. These only last from 1 to 2 years it seems.
I have Roxio program for burning DVDs and CDs that came with my PC. Possibly a year or two ago, maybe even three but doubt it, I bought a DVD burner. My PC has a AMD Athlon 3200 with 1.5G of RAM I believe. The burner would usually read the disc at about 10.2+kbps when sending to the ext. HD and completely copy to new DVD in about 20 min. Which with all the processes I thought was about avg. Now, the discs are reading at about 2.3kbps and takes almost the entire time of the movie just to send to ext. HD. Copying direct is not an option. So, I try to copy off the ext. HD and it starts for maybe a min then it says it's done, and now I have a coaster. A friend told me that it might just be that the processor is old or the BUS is too slow. Might have to replace processor, or motherboard. What are your thoughts as I am obviously not an expert on fully troubleshooting.
