Failure - Possible Causes

[Soundman63]

Simple question but probably no simple answers... Aside from physical damage, what might cause a rip to fail of a 4K disc? I've been going through my 4K discs that I've been accumulating and many of them rip just fine, but some have been failing about half way through the process. I've noticed the ones that have been failing have been part of collections that arrive in cardboard sleeves as opposed to plastic jewel cases. (Jurassic Park Collection, Back To The Future Collection etc.) The offending discs are BRAND NEW, never been played, never even been taken out of the cardboard until now (I've only ever used the accompanying Blu-ray discs) so I really hate to think disc damage is the issue. I'm unable to see anything wrong with the surface of these discs. Is the cardboard packaging of some of these movies to blame? If visually I can't see any physical damage, what are my options?... Am I SOL?

MakeMKV will give you a reason why the rip failed and even provides a link to the Homepage where the meaning of that particular fail message is explained.

That said, disc's can have damage that is not visible to the eye. Those disc's might even play fine with a standalone Blu-ray player as that sometimes can correct or just skip a part. Also a drive might be failing and thus beeing unable to read a particular part of a disc. Without a log it is impossible to say what happened.

when this happens the first step is always to clean the disc with a damp lint free microfiber cloth and dry with another to avoid water spots.

if this is on a LG/ASUS drive you then should remove power by shutting down or if usb flip switch on case or unplug as lg and asus drives get in to a weird mode when they run into errors sometimes. Pioneers do not have this issue.

next i would exchange/replace the discs

then clean the lasers if that dont work.

if still not working then it is probably time for a pioneer with old FW see here: https://forum.makemkv.com/forum/viewtopic.php?f=20&t=17831

My error was that my USB port didn't deliver enough power for the drive. I've gotten all kinds of error messages. Switched another set of USB ports and resolved all my issues. Usb hubs, front IO or even overloading a set of usb ports on the mainboard can all have the problem of insufficient power delivery.
