[Bug-gnupod] ipod trouble

[will law]

hi there, 

i have an hfs formatted ipod i'm having trouble with.  i'm working my way 
through the tutorial at:  http://www.gnu.org/software/gnupod/gnupod.html

when i get to the convert your ipod section i do:

        dd if=/dev/zero of=/dev/sda bs=1M count=10
        rmmod sbp2 && insmod sbp2

which both go fine, but then i try to use pc-fdisk:

        /usr/sbin/pc-fdisk /dev/sda

and i get:

        Unable to open /dev/sda

when i type rescan-scsi-bus.sh  i get:


        Host adapter 1 (ide-scsi) found.
        Host adapter 0 (sbp2_0) found.
        Scanning hosts  1 0 channels 0 for
         SCSI target IDs  0 1 2 3 4 5 6 7 , LUNs  0
        Scanning for device 0 0 0 0 ...

        1 new device(s) found.
        0 device(s) removed.

dmesg gives me something like:

        blk: queue cf9cca14, I/O limit 4095Mb (mask 0xffffffff)
          Vendor: Apple     Model: iPod              Rev: 1.30

        scsi singledevice 0 0 6 0
        scsi singledevice 0 0 7 0


and finally lsmod gives me:
