I have a T-30 IBM Think Pad: 256MB 18.63 GB, OS: MS 2000 Pro, GenuineIntel Family 6 Model 8 896. Problem: Matshita DVD-Rom SR-8175, which is the D Drive, suddenly does not recognize a blank CD-R disc. Text box says "Please insert a disc." It will recognize and play audio discs and other cd-rom discs that already have data stored on them. Won't play DVD video
