Thanks Osprey4. Unfortunately, I don't have any labels such as "UpperFilters" or "LowerFilters" under the registry entry that was mentioned.
Are there other solutions?
I'm just taken aback that MS Critical Updates would do this to my DVD drive. This shouldn't happen.
Ok, I want you to start a new thread, and include your model and OS, and a description of exactly what the drive can and cannot do.
And do not be surprised by anything MS updates might do.
I had the exact problem and went to the link you suggested and solved my problem. FYI: I called a computer repair company and they said I needed a new hard drive to solve this problem. Another company said my external drive was bad................ So thanks again, problem solved!!
Osprey4 - I started a new thread entitled, "Dell Inspiron 1750, Windows 7: HL-DT-ST DVD+-RW GT10N is not working after MS Critical Updates."
Will you continue to help me or point me in the right direction?
