partitioning - Unclear about partition tables and copying full disk with dd - Ask Ubuntu

i don't understand how dd treats partition tables when copying full disk. i backed whole disk (which had multiple partitions) using sudo dd if=/dev/sdb conv=sync,noerror bs=64k | gzip -c > /media/notsdb/backfile.img.gz now have brand new disk without partition table want put these partitions onto. reverse command should gunzip -c /media/notsdb/backfile.img.gz | sudo dd of=/dev/sdb conv=sync,noerror bs=64k . make sense , have put partition table onto disk first? (the operation takes 10 hours i'd know before it) thanks, craig copy over, use gparted (or similar) resize / move partitions - dd recreate old partition scheme, bitwise copy & applies no 'intelligence' operation. this works if new disk same size or larger!
