Help with HARDWARE ERROR:TIMEOUT ON LOGICAL UNIT

[knobbi]

Hi-ya,

Is there anyway to work around a bad disk?

I have a few DVDs (not bluray) that wont rip because of, well, i don't know, manufacturing faults?

MakeMKV v1.9.7 linux(x64-release) started
Using direct disc access mode
Title #1 was added (7 cell(s), 1:09:05)
Operation successfully completed
Saving 1 titles into directory /home/knobbi/Desktop/
Error 'Scsi error - HARDWARE ERROR:TIMEOUT ON LOGICAL UNIT' occurred while reading '/VIDEO_TS/VTS_01_1.VOB' at offset '2274492416'

Failed to save title 0 to file /home/knobbi/Desktop/title00.mkv
0 titles saved, 1 failed

Is there any way to work around these problems?
If that means that there's a little bit of corruption in the video stream for a second, I can live with this.

thanks,

Are you talking about a bad DRIVE or a bad DISK?

The errors you show are that the drive didn't respond with data in a reasonable amount of time. If it occurs on many disks, then you might want to clean the drive, and possibly look at another drive.

To answer my own question ...

You can pre-rip the DVD in question with dd if=/dev/sr0 bs=2048 conv=noerror > Desktop/blah.iso

The conv=noerror tells dd to ignore errors.

And then mount this image for MakeMKVing. I don't know if all the errors in the image will break the MakeMKV part of the process, as my DVD is still ripping. Looks like the 2nd-half of the disk is in a really bad way

A bad disk. The drive seems to function perfectly well otherwise.

MakeMKV may go through the ISO without issue, but you're going to run into problems with any playback or post-processing.
