Issues with certain movie BR discs.

[ashman]

I am trying to backup three separate movies using the BR drive in my Mac which is running 10.9, the drive in question is this model:

GGW-H20L with firmware YL03

The three movies in question, appear to backup fine until that final 3% or so of the backup when an audible clicking sound can be heard coming from the drive, this goes on for anywhere from 5-20 minutes until the process fails. I don't have logs handy, but will try again and post them.

All of these are newly purchased discs, so they have no scratches, and I cannot believe that they are defective?

Does anyone have an ideas?

The films in question are:

Dan in Real Life
Batman Begins
French Kiss

Here is the log which results in the failure.

The drive is telling the operating system that it can't read parts of the disks.

If this happens with particular disks, but not others, it could be the disks themselves. Cleaning them would be the next step. They could also be poorly mastered; if they're new, I'd suggest getting them replaced.

If it happens with a LOT of disks, there could be a hardware reason for it, as in a problem with the drive itself.

Thanks but this sounds like a canned response.

It doesn't make sense to me that I would have to clean a brand new, newly opened disc, what would there be to clean?

It also doesn't make sense to me that it could be poorly mastered, I have three BluRay movies, is each of them poorly mastered?

Why this program fails on just these tree discs and not the many others I have tried, I do not know, but the reasons you have provided do not make sense to me.

Thanks.

You are right that this is a canned response, because your logs show a common problem:

Error 'Scsi error - MEDIUM ERROR:1090' occurred while reading '/BDMV/STREAM/00882.m2ts' at offset '8209956864'
Error 'Scsi error - MEDIUM ERROR:1090' occurred while reading '/BDMV/STREAM/00882.m2ts' at offset '8210282496'
Error 'Scsi error - MEDIUM ERROR:1090' occurred while reading '/BDMV/STREAM/00882.m2ts' at offset '8213102592'
Error 'Scsi error - MEDIUM ERROR:1090' occurred while reading '/BDMV/STREAM/00882.m2ts' at offset '8268546048'
Error 'Scsi error - MEDIUM ERROR:1090' occurred while reading '/BDMV/STREAM/00882.m2ts' at offset '8268546048'

So, what can cause the drive to have an error with the medium (the BD)?

Dirty or scratched disk. Solution: Clean it.

Disk that has internal flaws. Solution: Get it replaced.

Optical drive is failing. Solution: Replace drive.

Note that this error is at the OPERATING SYSTEM LEVEL. OSX said the disk is unreadable, and MakeMKV simply reported it to you. OSX didn't say why, because it probably doesn't know.

It is possible that, by increasing the number of retries MakeMKV does when it gets errors like this, eventually the disk will be read. You can try that; it's in the Tools->IO menu, "Read retry count". Default is 5. Set it as high as you want, but 10 tries is usually enough to say the drive isn't going to figure out what is on the disk. Give it 100 if you have time to wait for it and really believe there is nothing wrong with the disk or the drive.
