And why doesnt the bootblock get copied when using identical discs and
making a dd if=/dev/had of=/dev/hdb?

On other machines, like HP, Sun, freebsd etc. you have /dev/rdsk<something> 
which is the raw device and a /dev/dsk<something> which is the block device.
AFAIK you dont have this on linux, do you?
