seriously need a update to make mkv.

No version of MakeMKV can deal with a disk that the drive cannot read. By the error messages in your log, at least one of the drives tries so hard to read the disk that it stops responding to the operating system for a while (device i/o errors).

Have you tried cleaning the disk?
