Prosty sposob na przetestowanie czy dana płyta jest do użytku
Sprawdzanie jakości nagranej płyty
Do sprawdzenia jakości nagrania użyjemy prostego konsolowego programiku cdck
Najpierw instalujemy program
aptitude install cdck
Teraz wkładamy płytę do napędu otwieramy ulubiony terminal i wpisujemy do niego
cdck -d /dev/hdX -t -v
-d /dev/hdX --urządzenie pod ktorym mamy napęd np /dev/hdc,/dev/cdrom,/dev/dvd
-t --program wykona test plyty
-v--zrobi to w sposob gadatliwy
Przyklad użycia
$ cdck -d /dev/hdd -t -v
Track list (1-1):
1: 00:02:00 (sec: 000000) data
170: 70:35:51 (sec: 317526) data (leadout)
Disc status: data mode 1
Multisession: 0
Audio status: no status

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.

317524 ok
CD overall:
Sectors total: 317526:
Good sectors: 317392:
Bad sectors (incl. with poor timing): 134
CD timings:
Minimal = 2 usec (0.000002s)
Maximal = 745524 usec (0.745524s)
Average = 985 usec (0.000985s)
Conclusion:
Disc contains BAD or even unreadable sectors, put it into trash can!
Jak widać płyta jest częściowo nieczytelna.
Program obsługuje plyty zarówno CD jak i DVD.
Dodam że innym bardzo dobrym programem (graficznym ) do tego celu jest
dvdisaster
Pozwala nie tylko na testowanie płyt ale również na odczyt danych z uszkodzonych nosników.
