Titolo: Masterizzazione OK, ma CD illeggibile

Uso cdrecord in linux, masterizzatore rilevato come:
scsibus0:
        0,0,0     0) 'CD-RW   ' 'CDR-5S40        ' 'ZSG7' Removable CD-ROM
Ho comprato dei CD Waitec (con i TDK non ho problemi) aventi per codice
CDR80WT40SC, 700MB, 40x.
Li masterizzo a 12x, e la masterizzazione va bene. Solo che poi non li
leggo (masterizzo CD dati); il lettore praticamente non vede il disco,
mentre se li provo a montarli col masterizzatore ottengo:
attempt to access beyond end of device
0b:00: rw=0, want=33, limit=2
isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=32
mount: wrong fs type, bad option, bad superblock on /dev/master,
       or too many mounted file systems
La cosa strana è che se provo a masterizzare lo stesso supporto,
cdrecord (almeno inizialmente) me lo lascia fare, quasi il disco fosse
vuoto.

Ma tutti questi dati non dovrebbero essere illeggibili, dopo la
masterizzazione?
E se provo a "fissare" il CD:
pupilla:~$ cdrecord -v -v -fix

 Qualche suggerimento?
Tutti quegli errori dell'ide-scsi non mi piacciono per niente. Te li fa
anche con altri dischi o solo con questi? Nel secondo caso, opterei per
una partita difettosa.
