Avatar Failed to Backup

[dolione]

Finally got around to backing up my collections of BluRay movies. Was successful with several movies until I got to Avatar, and can not understand the problem with this movie. Relatively new to this and need your help in solving this issue.

This is the first I've read of an internal (ish) drive behaving this way. Is the "external drive" really the Matshita UJ260AF in an external case?

With the exception that the track following error occurred during the scan, the symptoms are similar to what often happens with USB-powered optical disks. But so early in the read, I would suspect the BD itself before anything else. Make sure it is clean, no scratches, and that there is no issues with separation of the layers, particularly near the hub by the directory.

The power issue comes into play when the drive starts to spin at maximum speed during the rip; they run out of available power, and the drive electronics reset. You get I/O errors that come and go.

Laptops are notorious for not having enough power on the USB bus if they aren't attached to their charger. And if you have a hub between the laptop and the optical drive, you are reducing the available power even more. Try it with the MacBook plugged in and the drive plugged directly into the computer.

Thanks Woodstock for your response. I took your advice and connected the External BD drive to its own power cord, as well as plugged in my Macbook Pro. Re-backup Avatar and got the same error message. The disc is clean and free from scratches, so I am still at a lost on what to do.

It actually got further along than the previous log...

Given that the same error (NO SEEK COMPLETE) occurred at a point significantly AFTER the first failure, I'd say the disk isn't the culprit.

When it rips, what read rate are you at when it fails?

[dolione]

Yeah, I was excited that it might actually finish backing up without fails - but that was short lived. That said; here is what the log stated when it failed to backup:

Read rate: 8.0 M/s [0.9X]

[Woodstock]

Not that it helps you that much, but... I just did a backup of the 2010 "Blu-ray/DVD combo pack" edition, and reading 00002.m2ts it hit over 5x read rate about half way through, before I got distracted by work-related things. So the decoding of the disk isn't something that would keep the read rate down.

What do you have the retry attempts set to (Preferences->IO) ? It is POSSIBLE that increasing that would let MakeMKV wait out the time the drive is off-line...

[dolione]

My Preference I/O is set to 5, should I change it to 10 instead?

[Woodstock]

5 is the default. I'd give it a try with 10. I have used as high as 25 when dealing with known-bad disks, but rarely is it necessary to go over 10.

[dolione]

So I changed the Preference I/O setting to 10 and retry Avatar without success. I have tried other movies without a single problem, so at this point I gave up on Avatar. Thanks for trying Woodstock!
