Hello! I noticed that not all the sectors at the end of a CD-R are being read, I noticed this when verifying disc images made by different programs such as Alcohol 120%. A screenshot and explanation of what seems to be happening here: https://github.com/claunia/DiscImageChef/wiki/Bugs-in-other-dumping-software This only seems to happen with CD-R discs, and I've tested it on two completely separate drives and computers. EDIT: Log is of dumping a disc, I can provide one for verifying a disc too if you need it.
