[SOLVED] duplicate/clone an xbian installation

[kas_27_es]

At last, today I've tried to duplicate my SD using DD command...

It didn't work.

I'm using this:

Terminal

sudo dd if=/dev/sdb of=xbian.back.img

Apparently this instruction works fine, but when I try to do the duplicate with:

Terminal

sudo dd if=xbian.back.img of=/dev/sdb

New SD doesn't work... I'm frustrated...

Xbian version: xbian beta 1.1
Linux version: xubuntu 12.04

Any help?

Thanks...
