sata: manca il block device

[sneak]

salve a tutti.
ho da poco installato un nuovo hd serial ata sul mio pc ed ho dei problemi a farlo vedere al mio linux suse 9.2.
son sicuro che il controller sia configurato e che in fase di boot venga visto ma sembra che manchi il block device relativo.
Ecco l'echo del dmesg: come si vede ho anche un sottosistema scsi....

ma che sia da creare manualmente il block device con mknod??
se faccio cfdisk /dev/sdb mi dice che non esiste il disco... e se vado in dev effettivamente sdb non c'è!

Cosa devo fare?

ho risolto...
mknod /dev/sdb 8 16
e ho creato il block file...
