       Sometimes yes sometimes no !

       It seems it depends on how the modules are loaded. Yesterday I noticed
       that when it worked after a reboot I got an sd_mod module :

       #### rabeson:{root}:/var/log > lsmod
       Module                  Size  Used by
       sd_mod                 17217  0 
       sbp2                   24076  0 
       scsi_mod              122445  2 sd_mod,sbp2
       ohci1394               35784  0 
       ieee1394              298228  2 sbp2,ohci1394 

       which I did'nt see yesterday.

       Today I could see it after many experiments.
       I suceeded by loading modules in that order :

       rmmod  sbp2
       rmmod  sd_mod
       rmmod  scsi_mod
       rmmod  ohci1394
       rmmod  ieee1394
       
       modprobe -v ohci1394            # load ieee1394 and ohci1394
       modprobe -v sbp2                # load scsi_mod and sbp2
       modprobe -v sd_mod              # load sd_mod

       but I wonder if the problem commes from the modules, hotplug ...
       and if I have to config something.

       If I unplug the disk I losse it:

       #### rabeson:{root}:/home/users/sbob > cat /proc/scsi/scsi 
       Attached devices:
       
       but if I plug it again it reapears :

       #### rabeson:{root}:/home/users/sbob > cat /proc/scsi/scsi 
       Attached devices:
       Host: scsi2 Channel: 00 Id: 00 Lun: 00
