J'ai testé ca et malheureusement ca ne donne rien de mieux.

D'autres pistes non plus :

le partitionneur de suse ne voit pas le disque externe, seulement les 4 disques 
internes (sata ) 




j'ai fais un /cat/proc/scsi/scsi :


# cat /proc/scsi/scsi
Attached devices:

là on voit que zéro, un et quatre sont occupés par mes disques sata (Host: 
scsi0, Host: scsi, Host: scsi4)

Quand je veut forcer le scan des hotes 2 et 3 ca ne donne rien de plus (pour 
tenter de peupler le fichier proc/scsi/scsi)  : 

# echo 'scsi add-single-device 2 0 0 0' > /proc/scsi/scsi



là aprés un reboot du pc :

si je débranche et rebranche le disque externe , ca ajoute des lignes en bas :
