Hi, > I hope I'd followed your recommendation correctly.
The xorriso command looks ok. If you do not plan to produce and burn add-on ISO sessions you may omit option -multi. > I burnt a second copy of each ISO, which should > give me a high probability of full recovery using gddrescue, if the time > comes. You should record own checksums additionally to those of the media which decide over read succes versus i/o error. After some rescue tool pieced together an alleged repaired version of the ISO you need means to verify this. xorrisofs offers option --md5, xoriso offers command -md5 "on". Both will put MD5 sums into the ISO which can at any time later checked by xorriso commands -check_media and -check_md5_r. > during the formatting stage, each successive status line reported > progress as 1%. It depends much on the willingness of the drive to indicate progress. libburn sends a SCSI command to which the drive is supposed to reply a number between 0 and 65535. This number represents a range of 0 to 100 percent. For reasons of plausibility i rather map it to 1 to 99 percent. So probably your drive returned 0 all the time.
