how to create a dd image of the data parititon for ipt2?

[GoogleCodeExporter]

when i use ./dump_data_partition.sh  to create a dd image of my ipt2.
it shows an error:
dd: opening `/dev/rdisk0s2s1': No such file or directory
dd: opening `/dev/rdisk0s1s2': No such file or directory

ipod touch 2.ios 4.2.1


and i check my path /dev , there is no rdisk0s2s1,rdisk0s1s2.
what is the meaning of rdisk0s2s1 and rdisk0s1s2?
how i can fix it?
thank you!

try changing the last line of the dump_data_partition.sh script to

ssh $SSHOPTS root@localhost "dd if=/dev/rdisk0s2 bs=8192" > $OUT
