ho fatto ulteriori prove con cd e dvd che mi funzionano senza problemi, che quando ho creato avevo spuntato l'opzione "verifica al termine". Continua a darmi sempre.
md5sum: /dev/hdc: Input/output error

fatto test con cdck:
test cd 1
$ cdck -i -t -p -v

Try to find out what sort of CD this is...
CD-ROM with iso9660 fs
iso9660: 693 MB size, label 'XP-WINDOWS7 '
Creating software: 'ULTRAISO V9.2 CD & DVD CREATOR, (C)2008 EZB SYSTEMS, INC.'
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.
