I erased as suggested a Verbatim BD-RE DL. Then began burning a file from my hard drive to the disc using an Samsung SE 506 BB Everything was going along fine until it was 58% finished. The last message on the log was Writing layer 1 (LBA12219392-22165375) There are no yellow error messages but the write rate is 0 KB. Time remaining is unknown, size and time are not throwing out new numbers. There are no write retries. The only thing changing is time elapsed. It has been like this for at least 45 minutes
