Cercando di fare un backup il programma di masterizzazione (k3b) mi ha risposto picche a meta' dell'opera e sto cercando di capire quale sia il problema e come risolverlo. Il log di k3b non l'ho salvato (sigh) ma dmesg mi dice una serie di cose non belle e (a me) non chiare sul lettore . Lo riporto (opportunamente riassunto) di seguito. Una cosa che mi stupisce MOLTO e' che ogni pochi secondi ho una nuove riga di questo tipo in dmesg dopo che faccio partire X: sr0: CDROM not ready. Make sure there is a disc in the drive. sr0 e' il lettore CD/DVD (il masterizzatore e' sr1 che punta a scd1): lr-xr-xr-x 1 root root 4 dic 29 12:53 /dev/sr0 -> scd0 lr-xr-xr-x 1 root root 31 dic 29 12:52 /dev/scd0 -> scsi/host0/bus0/target0/lun0/cd brw-rw---- 1 pippo cdwriter 11, 0 gen 1 1970 /dev/scsi/host0/bus0/target0/lun0/cd Ecco l'output di dmesg, spero di riportare tutto cio' che e' utile: ...
