firewire damaged disk

[Jean-Christophe Michel <jc.michel@symetrie.com>]

Hi all,

I'm trying to make a lowlevel copy of a damaged ide 2.5" hd (using dd).
I placed it in an external firewire box, and when plugged in to my
debian unstable 2.4.23-ben1 pismo, i get in syslog:

18:42:55 kernel: ieee1394: Stopping reset loop for IRM sanity
18:42:55 kernel: scsi1 : SCSI emulation for IEEE-1394 SBP-2 Devices
18:42:55 kernel: blk: queue ef7b2814, I/O limit 4095Mb (mask 0xffffffff)
18:42:56 kernel: ieee1394: sbp2: Logged into SBP-2 device
18:42:56 kernel: ieee1394: sbp2: Node 0-00:1023: Max speed [S400] - Max
payload [2048]
18:42:56 kernel: ieee1394: Node added: ID:BUS[0-00:1023] 
GUID[0030e001e0000b80]
18:42:56 ieee1394.agent[4605]: kernel driver sbp2 already loaded

And nothing more.
If i try  dumpe2fs /dev/sda :

dumpe2fs 1.35-WIP (21-Aug-2003)
dumpe2fs: Aucun périphérique ou adresse while trying to open /dev/sda

sr0 or sda0 to 15 don't give a better result.
I think the disk isn't loaded at all.

Is there a lower level to address a disk via firewire ?
