[ubuntu-it] cdrecord

[spa]

sto scrivendo uno script che mi crea il backup di tutti i pacchetti
installati (con APT-MOVE) e di seguito masterizzare il cd per poi usarlo
su pc dove non c'è la connessione.

se vi va di analizzarlo e magari mi date qualche dritta, lo script
(ancora da ottimizzare) lo trovate su
http://web.tiscali.it/openallnight/cc_.sh

uso Breezy

praticamemte ho già fatto tutto e tutto funziona, solo che cdrecord mi
dà dei problemi non indifferenti.

la storia sta' cosi:

i comandi dentro lo script incriminati sono questi:

cdrecord -v speed=0 -eject -multi isoimage.raw
cdrecord -v blank=fast -force speed=0 
cdrecord -v blank=all -force speed=0 

IL problema è che alcune volte mi ha funzionato, ma la moggior parte
delle volte no.........non riesco a capire la logica nel momento in cui
fuziona.
ho provato in mille modi, dando anche il device in mille modi possibili

e il risultato è questo:

Pensando che dovevo cercare di liberare il device.... ho usato il
comando di cdrecord reset e abort, ma una sola volta ha funzionato. 
dal man di cdrecord:

-reset Try to reset the SCSI bus where the CD recorder is located. This
works not on all operating systems.

-abort Try to send an abort sequence to the drive.  If you use cdrecord
only, this should never be needed; but other software may leave  a
drive in  an  unusable  condition.  Calling cdrecord -reset may be
needed if a previous write has been interrupted and the software did not
tell the drive that it will not continue to write.

MI AIUTATE??
