Hi
I m trying to copy my discs
and sometimes i needed to clean brandnew discs to work
but now i havve a disc, where i cant even manually read out the aacs folder in windows explorer, makemkv throws scsi errors
Tried a friends drive, and he can read the disc, so i will get my copy that way
but, does this mean my drive is maybe not optimal adjusted, or incompatible
i was able to read the seasons before, and also other discs from that season, so it must be something special to this disc
the friends drive is another type of uhd friendly, mine is bu40n, his is a different brand working out of the box
Is my drive broken?

Re: Is my drive broken?
What drive do you have? What is your info in MakeMKV?
I have an issue where some UHD disks will not read in my drive. I bought a pioneer drive that will hopefully handle these (fingers crossed, eyes too

Re: Is my drive broken?
I have three drives.
One external USB ASUS (Pioneer inside).
Two internal ASUS drives (allegedly LG drives)
All three behave differently on problem discs. Although the Pioneer is by far the most stable
and has less issues with discs.
I have had several (+20) discs that can't be read at all on the internal drives. Some have been able to
be read, but a really low speed. The Pioneer have read them without issues at its full speed.
I have had in total 5 discs (of +1200) that have not been able to be ripped no matter the cleaning done.
None of these 5 discs had any scratches, 4 of them were never even used before and with the plastic over
the cover before I tried to make the rip.
Of these 5 the Pioneer couldn't even reqognise two of the discs. One of these the internal had no issue
with reqognising. Although then failed at the same place every time while ripping.
The other four stopped at the same place during the rip with either drives.
Again no matter how much cleaning done. Had to replace them and the new ones working without issues.
In total I think the Pioneer only failed to outperform the internals on two discs.
My take on this is, first make sure you have a quality drive, second never try to rip discs without atleast
making a quick cleaning. Even if the disc "looks clean".
Some discs are simply "broken". They may work on a bluray player were error correction is at work.
It is impossible to own 15 different drives, some drives may read a problem disc for various reasons.
Some times you simply need to go to a friend and do the rip.
However, if the drives start acting up on several rips then there may be an issue with it.
