Do Inconsistent Errors Always Mean A Failed Drive?

[snthsnth]

I have an LG BP60NB10, some UHD discs and some Bluray discs read properly, but others fail with M2TS errors and CDB errors. For example, Starship Troopers UHD and Austin Powers International Man of Mystery Bluray all work fine. Starship Troopers Bluray and Apollo 13 UHD do not work.

Is this a sufficient sign of a failed drive that I should return, or is that more an indication of failed discs?

I have an LG BP60NB10, some UHD discs and some Bluray discs read properly, but others fail with M2TS errors and CDB errors. For example, Starship Troopers UHD and Austin Powers International Man of Mystery Bluray all work fine. Starship Troopers Bluray and Apollo 13 UHD do not work.

Is this a sufficient sign of a failed drive that I should return, or is that more an indication of failed discs?

HOW do the discs fail? Do they start the rip & die somewhere in progress? Or, w/ UHD (see FAQ), is the log reporting volume key not found? A log helps people trying to assist.

Sometimes, all that's required is cleaning the disc w/ a lint-free cloth. Sometimes with a little mild soap/water. No matter how pristine a disc may appear to the human eye,a laser is more discerning.

Sometimes the disc is bad. Could be a bad pressing? The higher the data density of the disc (UHD 3-layer are the most difficult), the more likely a drive may take issue.

With LG and Asus drives you need to reboot them anytime they do stuff like that.
It very common it's not failed but some drive require a reboot after every disc.
Really they are just annoying sadly.

Pioneers are not like this they are way better but you need them with old fw and only a few have them me Marty and Asmcom are the only ones I know of with latest Gen pioneers with old fw

Since I didn't save a copy of the logs, so I retried the non-working discs. The Starship Troopers Bluray worked without issue this time.

EDIT: I should add, I tried unplugging and replugging the drive, gently cleaning the discs, and removing, rotating, and reinserting discs, without any apparent change.

I pruned out a bunch of duplicate 'corrupt or invalid' messages, I was around 120k characters with them in.
