Yes, I tried this yesterday. Using dd to write the image to sdb which
was an unmounted/empty disk worked properly.

So the problem only happens when overwriting the live system in either
Etch or Squeeze. Lenny works exactly as expected so I guess I could try
upgrading the remote server from Etch to Lenny and then do it, but it
still seems odd that it would not work in Etch, work in Lenny, and then
not work again in Squeeze.

Thanks,

Hmm, perhaps your live system is performing some disk writes *while* your dd is doing its thing, thus effectively overwriting (corrupting) some sectors already written by dd?
