So far I have only really encountered this “fatal reading behavior” when my LG drives are copying *.VOB files from dvd discs which are either defective and/or badly damaged. On the older dvddecrypter ripper program, this “bulldozing” over bad/unreadable sectors is detected when an error message indicating the mpeg2 header is missing from the first four bytes of a sector (ie. 0x000001ab).
On the other side of the coin, this “fatal reading behavior” is good for spotting new errors or disc rotting on discs which I have previously checked on my other drives (such as LiteOn which doesn’t have this “fatal reading behavior”).
There are some reports of LG manufctured bluray-r drives having this “fatal reading behavior” when reading badly damaged bluray discs. Though I have not encountered it yet myself.
I tried ripping the isos from various damaged cd-rom data discs I have (mostly from old pc games). It didn’t trigger this “fatal reading behavior”.
I have no idea what criteria these LG drives use to trigger this “fatal reading behavior” bulldozing, other than it affects *.VOB files from heavily damaged/defective dvds and possibly *.m2ts files from heavily damaged blurays.
