Hardware or software problem?

[crt1948]

Hello,

First, MakeMKV is great so thanks!

I have a Samsung portable Bluray ripper that I have successfully used previously with MakeMKV for both Bluray and SD rips.

However, I am now getting an error when trying to rip my copy of the Strangers on a Train Bluray. This is what appears on my screen:

MakeMKV v1.7.10 win(x64-release) started

Failed to open disc

Can someone tell me what this means? Is there a problem with the drive, the software or the disc itself? It has happened a couple of times on other discs.

Thank you.

Can someone tell me what this means? Is there a problem with the drive, the software or the disc itself? It has happened a couple of times on other discs.

These are all possible explanations:
1. Dirty disc. Clean carefully and try again.
2. Scratched/damaged/defective disc. Exchange for a new disc.
3. Dirty, damaged or misaligned blu-ray drive. Try a different drive.

NOTE: Due to the index of refraction, reflectivity and other characteristics of the hard coating on a blu-ray disc, one which looks (by casual inspection) to be clean and scratch-free may be neither of those things. Examine very closely, focusing your eyes on the surface of the clear coating rather than the reflective layer beneath it. (It is MUCH easier to see scratches/scrapes on DVDs and CDs than it is on Blu-ray discs.)

Also, scratches and scrapes are not the only kinds of flaws that can occur. There is a manufacturing defect I have seen on some discs which causes the surface of the clear coating to be slightly rippled in a few spots rather than flat.

Good luck,
Dave

Thanks for the tips.

It looks like my problem was solely due to "operator error" as I was using the portable Bluray drive plugged into a different PC and failed to note the USB drivers did not load properly when I initially plugged the drive in.. On the second attempt, all went well and I have successfully ripped since then. Sorry.

It's a bit odd that a driver problem would cause an uncorrectable medium error, but I'm glad it worked out for you.
