RE: Cannot Recognise External Drive (sbp2 problem?)

Hello,

I'm having trouble recognising my external firewire drive (Maxtor 40 GB). I
am using Knoppix 3.3 (the kernel is 2.4.22). I'm not sure what version of
linux ieee 1397 I'm using :( I know that the firewire PC Card I'm using is
OK as I used it with other linux distros as well as Knoppix 3.2 previously
(which had no problems recognising my drive, showing the partitions on the
desktop).

Can anyone suggest what I can try to solve this problem? I'm not very
experienced with Linux, but am always willing to have to go :) Below is the
relevant information (following the troubleshooting guide on the linux 1394
website).

Cheers,

Chris

-------------------

With Knoppix 3.2 ("Linux version 2.4.20-xfs"), the drive is automatically
recognised at boot, and the partitions are displayed on the desktop. Here
are the relevant parts of lsmod:
sbp2 16288 1
ohci1394 15688 0 (unused)
ieee1394 29516 0 [sbp2 ohci1394]

With Knoppix 3.3, nothing. According to lsmod, the required modules are
mounted, but things are a bit differnent to 3.2:
sbp2 16524 0 (unused)
ohci1394 22888 0 (unused)
ieee1394 183332 0 [sbp2 ohci1394]

sbp2 does seem to be used - is this my problem? What should I do/try next?

Modprobe raw1394 (do I need this?) gives the following result:
knoppix@ttyp0[knoppix]$ modprobe raw1394
/lib/modules/2.4.22-xfs/kernel/drivers/ieee1394/raw1394.o: create_module:

The section of my dmesg where it refers to the modules:

p.s. Exact version of Knoppix I'm using (Sep build) from dmesg:
Linux version 2.4.22-xfs (root@Knoppix) (gcc version 2.95.4 20011002 (Debian
prerelease)) #1 SMP Fr Sep 19 17:55:45 CEST 2003

p.p.s I did try the tool 'gscanbus' (from one of the menus) - can't remember
exactly the outcome, but didn't solve my problem :(
