Are Scsi Medium Errors significant?

I'm new to using this program (and ripping in general) - just started using it a few days ago to try ripping the Star Wars Blu-Rays. So far I've done Eps. II and III. This is from Ep. I. Maybe something like that happened on the first two and I just didn't pay attention and closed out of it after seeing "1 titles saved".

I tried looking up info about this and saw that if something like happens, to perhaps clean the disc or the drive. But I also noticed that people were reporting their titles failed and didn't save. If mine saved, does that mean I don't have to worry about anything?

If having the title saved doesn't mean everything's ok, then is it possible to know if these are significant problems? Or could it just be single frames are messed up but I won't even notice watching it?

Still working on figuring this whole process out (figuring out how to get the forced subs on Ep. II was a nightmare and I had to figure out what all these different file types and programs were), so thanks in advance!

SCSI errors are the operating system reporting that the drive cannot read parts of the disk, so yes, they ARE significant.

Now, if retries allow it to read the problem area, then it's not a terminal condition. By default, MakeMKV will request a read 5 times before failing the track.

Thanks for the response! Ended up giving it another try and had no issues this time.
