DIC does not support those discs yet, it will abort reading as soon as protected area is reached.
One could use isobuster and replace those sectors by '0x55' bytes but we have not deceided yet if it should be '0x55's or can be '0x00's for example. If we consider '0x55' bytes then sarami could probably code DIC with that.
My talk to sarami about one of those discs:

I never came back to this topic though.

DVD's don't have bad sectors (afaik)

Here's is some info for DVD and BD (correction codes):

DVDs have RSPC code and can contain bad sectors but this has to be done in factory. I don't know if home devices can burn discs with incorrect correction codes...

@iR0b0t, LoStraniero91
Please tell me the disc title, region and barcode if possible.

Backcover does not have a barcode, it must be on the big box, which i don't have.

I don't know how the big box looks like, but i think its the correct one.
Its a german seller, they should sell german version.
One of the sellers from this listing has pictures which match my disc.
Seller's name: GameShop Eichhorn
It should be in general the correct listing.

The barcode is 4891779103179 .
It's also available on medimops.de.
There are other discs (CD's) with similar LL21 ringcodes and Ring protection:

Thanks info. Do these discs have the ring on the different file like

They are also inside large exe files IIRC, but the IFPI LL21 are different type than "Unnamed CD.IDX" because you can't dump them in DIC and the last sectors have to be dumped with cdarchive like Ring ProTECH.
