I have a Dell Precision M4300 laptop...just got it less than a year ago. It a has a HL-DT-ST DVD+-RW GSA-T11N DVD/CD burner. It used to burn both CDs and DVDs. Now it only reads both.
Before I insert a blank disk in the drive, the drive in Windows explorer shows as DVD-RW Drive (D:). Once I insert a blank CD or DVD it shows up as CD Drive (D:). When I drag files to burn a CD in Windows Explorer then click burn to disk, the message keeps telling me to insert a writable disk in the drive (it's already in there). When I load a blank DVD, the Roxio program autostarts, but then says no recordable drive found. Very weird. I have re-installe drivers, read a million posts. Any ideas how to fix this or do I have a bad drive. I HAVE NOT called Dell support as that is always a beating and they walk me through all the steps I have already taken.
