The Data DVDs that the drive cannot read: were they created on the system, or
were they created on a different computer? How were they created?
When the dribe shows in My Computer, does that happen all the time, or only
when a blank disc is inserted?
When you insert a blank DVD into the drive, Windows will not recognize it.
A third-party software (Roxio, etc.) is required for a blank DVD disc.
If the third-party software does nort recognize a blank DVD, it could be the
DVD. What is the brand of DVD?
