Seems as if your drive can't detect the discs properly for whatever reason
However I can burn DVD+R with both programs just fine.
I would really like to be able to burn DVD-R's can someone help me?
I'd stick with DVD+R then.
ImgBurn : 188.8.131.52.
Nero Brn. ROM : 184.108.40.206
Your software is ancient. I doubt, this will help, but you should consider updating both softwares. For Nero, get latest 7.x version (it's a free update).
Booktyping to DVD-R is not defined, but your drive should be able to set the booktype to DVD-ROM, if I remember correctly. EDIT:Booktyping is often disabled in OEM firmwares.
I suspect, there is something wrong with the drive. Have you ever been able to burn DVD-R?
I just saw, this drive is an OEM drive "made" for big name companies like Dell, HP etc. It might be crippled in some way. (No DVD-RAM support, no bitsetting,...)
Seems as if this is the same drive hardware as H10N or H12N.
But before you try this, I'd recommend to
- clean the lens (do not use a cleaning disc!)
- replace the IDE cable (should be 80wire flat ribbon)
- try the drive in another computer
