Package: cdck Version: 0.6.0-1 If I use cdck to verify a CD-R or CD-RW, it reports unreadable sectors at the end of the disc for several discs which are perfectly readable (I even verified MD5 sums for one disc).
Log: iota:~$ cdck Reading sectors 1-27280 ! unable to read sector 27259, reason: Input/output error [...all sectors in between with same message...] ! unable to read sector 27280, reason: Input/output error CD overall: Sectors total: 27280: Good sectors: 27258: Bad sectors (incl. with poor timing): 22 CD timings: Minimal = 5 usec (0.000005s) Maximal = 99340 usec (0.099340s) Average = 1161 usec (0.001161s) Conclusion: Disc contains BAD or even readable sectors, put it into trash can! This occured for several discs. The number of bad sectors reported varies from 14 to 24, but it is always the last sectors. Maybe cdck incorrectly detects the end of a CD? I also tried a real, pressed CD from retail: The problem did not occur. --------additional info----------------- Here are excerpted logs for some CDs I tested. They were burnt on different drives. I also included the volume size as reported by isoinfo -d (the line "Volume size is:"). Strangely, it does not agree with what cdck reports.
