Maybe bu I'm not conviced it works the way cdck uses linux/cdrom.h

I get:
% src/cdck -t
sectors = 253807
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.
Reading sectors 1-253807
! unable to read sector 1, reason: Input/output error
! unable to read sector 2, reason: Input/output error
! unable to read sector 3, reason: Input/output error
Cheers,
