dd if=/dev/hdX of=hd.img

We did this recently to copy harddrives. But you can do it to make an 
image on another drive and then transfer if thats what you need to do. To 
Transfer:

dd if=hd.img of=/dev/hdX

Then you can use any partition manager to resize. Or to copy right from 
drive to drive:

dd if=/dev/hdX of=/dev/hdY

On a 4G hd this won't take to long. But it can be sped up by changing the 
byte size:

dd if=/dev/hdX of=/dev/hdY bs=4096

The above copied an 80G drive to another in about 27 minutes. They were 
windows installations.
