BD-RE virgin disc write pre-erasure in ImgBurn Support Posted May 22, 2018 2. Due to the above, you should in theory never get a 'Write Error' when the drive's 'Defect Management' feature is enabled - and it's enabled when a disc formatted with spare areas is put in it. You might get an error if it's unable to reallocate the sectors (spare areas full) or if there's some other sort of issue with the drive/disc. Thanks for that clarification which does help in determining what is happening at what level (software or drive hardware) when exception conditions occur. I wrote to a Verbatim BD-RE-DL disc earlier (the original Verbatim production runs that were truly made in Japan) which was erase-formatted with spare sectors enabled, but during the full-erase-format process, did not yield any errors at all. Coming out of that I assumed the disc formatted flaw free and proceeded to write data to it and it was during the write-with-verify phase that the Pioneer 09-drive reported a single write error, which I thought was strange but assumed it would be taken care of by spare sector replacement. So a single error would not have caused a spare sectors fully depleted condition. I let the write phase complete and when it got to the verify only phase (reading at 2X), it got to approximately the same spot in the data (I am guessing based on the percentage reading of how far through the entire length of the data), the verify error prompt popped up and repeated retries did not resolve the problem. So I aborted the verify retry and abandoned the disc. I'm going to use a different Verbatim BD-RE-DL and repeat the entire erase-formatting with spare sectors enabled and then rewrite the data to it. This time I will try using the Pioneer 06-drive instead to see if it makes any difference. So it would seem based on what you describe the expected behaviour would be, the write error is an anomaly of unknown reason. Unfortunately, the Imgburn log has been overwritten, or I would have posted the relevant section here. If it happens again I'll make sure I do so. In general, my experience so far with erasure-formatting with spare sectors enabled and then subsequent data writes have been very stable under Imgburn. Overall, results have been generally excellent, and I'm pleased to see that I was able to use Sony BD-RE-TL completely normally right off the bat, though I am rewriting many of my existing BD-RE-DL discs because they previously were not formatted correctly (via Nero) and I am redoing all of them with spare sectors enabled to increase data integrity. I hope there will be a release of a much needed update of Imgburn in the near future to address all the various known bugs in the current 2.58 release from 2013, especially with higher capacity media now in use.
