After trying and reading a bit further (both in cdck and in

sectors variable by removing some conditions, but than I'm ending at:

sectors = 327782
NB! For disks written with some burners cdck might
report about unreadable sectors at the end of the disk.
In such cases you can just ignore those warnings.

This is not just a documentation problem - testing audio CDs is no
less possible than testing other kinds of CDs.
Maybe bu I'm not conviced it works the way cdck uses linux/cdrom.h
...
But adapting the
documentation and the behavior when this fails would certainly be
better than nothing.
I do not understand what you wrote about ReadTOC() and sectors_tot.
Maybe provide patches showing what you tested.

Ah, I see. Sorry, I thought 172 was a number of sectors.
Thanks
I get:

Then the last block is pretty much repeated again and again (at the
beginning, cdck reads a few blocks).
