I have an internal I/O Magic 4x DVD drive. I have not had any problems burning to DVD's using DVD creation software, nor have I found any problem when burning to CD's (audio or data). However, I recently purchased some DVD+RW's and found that it has trouble burning data. (Using DVD creation software is fine also with these DVD+RW's.)
It appears to format ok, and when I drag-drop files into the drive it works ok for the first couple of minutes. Then it slows down... It never actually stops, but slows to the point of taking about 5 to 10 minutes per file. Most of the time the light on the drive stays a steady green (indicating no activity), and then when the file finally writes it will flash red for a second or two and then another 5 to 10 minute wait ensues. It appears I also need to wait the same amount of time even to right click on the drive icon, or select "properties" from the menu when it finally arrives.
I am using Pinnacle's InstantCD+DVD that came with the drive, and I've recently upgraded it to the most recent version, but both versions exhibit the same behavior.
I'll appreciate any tips on what is going on! I suspect it is the operating system, as I've had issues with this drive (and all other cd drives) auto-detecting disk changes (namely, it does NOT auto-detect disk changes, and I need to disable/enable the drive from the device manager whenever I want the system to recognize the new disk).
