My CD ROM reads quite slowly compared to my other desktop. It is not related to dirt on the discs. The same discs were use in the comparison. Are there any settings I can play with or is there an upgrade I can purchase?
You have to check the original system configuration of your XPS 8930 to determine the part number of the CD/DVD drive to determine its specs. My XPS 8910 came with an 8x Hitachi slimline drive. The slimline drives used in the XPS 8910, 8920, & 8930 are like drives in laptops and are slower than full size CD/DVD drives in older desktops which can be 16x, 24x, or higher.
I found that my security app was making my dvd/cd very slow. There is a setting in my security app to exclude dvd/cd drive. Now it runs just as fast as any other drive I have had.
Check on that.
It appears the DU-8A5LH is DVD+R 8x, DVD-R 6x, and CD-R 24x. A typical half-height CD/DVD drive is CD-ROM 48x DVD-ROM 18x. So what are you comparing to in your other computer?
