hey JT340 Ive got a very similar problem using imgburn and
clonecd.
The project starts really well but always get to 50 or 51% then get I/O errors. the details are listed as servo spindle error and got all the same crap youve got about sectors etc,
Im using 8x Datawrite DVD +R DL discs and as far as i can see everything like bitsetting booktypin is bang on which possibly points to discs. Saying that my drive is bog standard drive GWA4164B hybrid drive but aint had problems with any other discs burning.
Its interesting that some files work though as Ive only ever tried the same Image.000/.DVD files maybe give a different one or slightly smaller one ago. Its the waiting to get them though thats the pain!!!
Since your last thread has the problems resolved in anyway or did you go for the verbatims??
