I have a HP 740b DVD/CD burner in an HP Pavilion 4100y system. The DVD burner part works fine but it will not burn CD-Rs. After about 12% I get an error saying there was a problem with making the CD and it bombs out. I have upgraded to the latest firmware, uninstalled and reinstalled the DVD driver and atapi controllers, made sure the advanced settings were set to DMA etc. I also had Sonic and Nero loaded and since I didn't like Sonic I uninstalled Sonic and left Nero. Still would not burn CD-Rs. I then uninstalled Nero and reinstalled it and no luck. Actually when I put the Nero diskin to reinstall I was getting a message saying there was no CD loaded so I had to use my other DVD-Rom drive to install.
The inept support at HP want me to do a destructive format and recover the system as it was originally shipped to see if it is a hardware problem. I really don't want to do this because it will be a big job restoring software and data files.
Does anyone know what else I can try to either fix this or determine if it is a hardware or software problem? Thanks.
