Hi all,
I have a Pioneer DVR107 and use Nero to burn my CD-R, DVD+R, DVD-R. Many of the disc i burned, no matter DVD+/-R even for CD-R format, quite a number of them when read under my Pioneer DVD writer is empty. I try to read it under different DVD Roms from my friends the disc is still empty.
Then i download the CD/DVD Diagnostic Evaluation to have a check for those discs i burned, there were detected as “unknown data track”. At first, this happened with my DVD+R disc, so i tried out DVD-R and CD-R, for both multi-section and finalized disc test, the result is still empty 
Is there anything wrong with my drive or Nero ??
And is there any software which can recover “Unknown data track error” disc ??CD/DVD Diagnostic cannot even display any file from the discs…
Thanks…
