For the N e r o CD DVD Speed software program suggest reviewing the â€œCD-DVD Speed - A user guideâ€ (http://club.cdfreaks.com/f96/cd-dvd-speed-user-guide-192563) and note the topic â€œScan Discâ€ surface scan (http://club.cdfreaks.com/f96/cd-dvd-speed-user-guide-192563/#post1540646). Any Bad/Red and/or Yellow/Damaged sectors indicate a poor quality problematic Burn. A quality error free Burn will not contain ANY Bad/Red and/or Yellow/Damaged sectors.
For the DVDInfo software program start the DVDInfo software program and on the top Menu bar click on the â€œErrorsâ€ CD icon. The â€œTest Your Media For CRC Read Errorâ€ narrative will appear. Click on â€˜Startâ€™ box and a graph will appear. The Scan should contain all Green/Good sectors - ANY Bad and/or Suspect sectors indicate a poor quality problematic Burn. A quality error free Burn will not contain ANY Bad and/or Suspect sectors.
Once again if the suspect â€˜data dvd rwâ€™ Media Disk contains any Cyclic Redundancy Check (CRC) errors (Bad/Red, Yellow/Damaged, and/or Suspect Sectors) will explain why this particular â€˜data dvd rwâ€™ Media Disk is not being recognized by your Optical Drive.
