Hello,

I had this error message while copying Looper Blu-ray:

Error 'Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR' occurred while reading '/BDMV/STREAM/00009.m2ts' at offset '236845056'

What can that be.

Thanks.

Try cleaning it first but more than likely replacing the disc is the solution. I recently had to exchange 3 copies of Monster's Inc before I finally had one that would rip correctly. All of them would play fine in our Oppo blu ray player.

Your drive couldn't read part of the disk. Try cleaning it.

MakeMKV (and any ripper, for that matter) want a 100% exact copy of the data on the disk. Your typical player, though, will accept unreadable data and skip over it, so a disk might "play" just fine, but be damaged.

Thanks a lot! I cleaned my disc and everything works just fine.

Thanks again!
