feature request for v1.17.10 (ignore read errors option)

[mas1701]

Hi,

instead of more "version bumps" without any further changes, how about an option to silently ignore read errors during full disc backup?

It has been often discussed that MakeMKV aborts full disk backup even if there is only a tiny error in a file that isn't even important for the disc to work.

So why not have an option to ignore these read errors? Just skip the faulty sector (replacing the content will all-zero bytes) and create a log entry like "read error in file x at offset y - writing zeros instead (file corrupted)"?

That should not be hard to do.

Thanks,

This capability would have been helpful for me during the James Cameron releases last year. I went through 3 copies of Aliens and one of the discs had different errors. With this capability, I might have been able to "piece together" a good backup.

Fully concur with mas1701's suggestion. If the o/s says "no", just thank it nicely and move to the next sector.
For minor scratches the resulting blip in the video would hardly be noticed, just like when played on a commercial player.

A plan that the program's author has actually talked about involves using more than one copy of a disc to create one 'perfect' rip.

This seems like it would allow MakeMKV to be sorta like a Domesday Duplicator but for blu-rays instead of laser discs.

Hi dcoke22
That would be great but for one big snag: most of us only own one copy of a disk. Staying legal, I would need to buy another copy - if indeed it is still available. And this would be impossible if it's a limited run DVD of, say, my child's school theatrical performance.
In my case I'm trying to rip my own blu-ray to a NAS for playing through my R_volution gadget so that I can store all the disks in a box in the man cave. It's quite frustrating when one episode of a 6-part TV series cannot be ripped because a fraction of a second of video is damaged and unreadable.

Many messages on this forum assure new users that their MakeMKV copy is not degraded in any way. It is an exact copy of the video and audio data on their disc. Taking from Marty McNuts, if you get errors then:

1. Your disc is dirty,
2. Your disc is faulty, or
3. Your optical drive is faulty.

I like this standard. How would you define "a small error" that would satisfy everyone?
