How many times can the Verbatim BDRE's be formatted?. I am trying to re-initialize one to Full Erase With spare areas,and preferred. Before erase disc was "without" spare areas. Everyone of these discs than had been previously formatted(Quick or Full) will just hang at anywhere from 28%-56%. Seems like a waste of computer time(energy),wear &tear,etc.Would TDK or Panasonic be Re-Formattable, i ask?. LG BE12LU38-Verbatim IM1-000. Also, you can't cancel operation in Imgburn. So what does one do?. Thank You
