I have 2 drives: a TSST CDW/DVD-TSH492A and a Sony CD-RW CRX320EE. The TSST came with my computer (Compaq Presario SR1503WM), the Sony was added to the expansion slot (it's only 6 months old). It worked perfectly in my old (dead) computer and my son has the same one his works as well. The Sony is a combo drive and I can burn/listen to CD's and watch DVD's but not burn them. It doesn't even recognize a blank DVD when I insert one. I've tried different brands/styles: Memorex DVD-R, Maxell DVD-R and Sony DVD+R (I now have a very large collection of drink coasters).
When I run Nero's info program, it's not even recognized as a DVD burner, only as a CD burner. The driver (it only came with Nero software, no driver included) windows uses is from 2001 so I tried "update driver", no go. I've also searched Sony's site for a driver (it doesn't even list the CRX320EE as a product) and the internet but there doesn't seem to be one. I thought of disabling the TSST to see if it's interfering but when I go to the properties the enable/disable drop down menu is disabled so it's not even an option. I've tried using different software (I really hate Nero) Roxio doesn't recognize it as a DVD burner & ConvertXtoDVD seems to recognize it as a DVD burner (it will at least tell me I have the wrong kind of Media installed and need to install DVD-R, RW, RAM or DVD+R, RW, RAM) but when I insert a blank disc it doesn't see it. It can't be the software because it was doing this before I installed Nero, Roxio or ConvertXtoDVD. I'm really a novice at this and don't know what to try next. I'm sure there's things I should check but not sure what to do now.
