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
Try to find out what sort of CD this is...
CD-ROM with iso9660 fs
so9660: 620 MB size, label 'grml 1.1 '
Creating software: 'MKISOFS ISO 9660/HFS FILESYSTEM BUILDER & CDRECORD CD-R/DVD CREATOR (C) 1993 E.Y'
Publisher: 'grml-live | grml.org'
bootable CD 

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.
