dd is fully capable of cloning files, partitions and whole disks. Not sure why it would show that in gparted. Anyway, this is a helpful page: https://wiki.archlinux.org/index.php/Disk_cloning
Not even the partition table!
Well /dev/sde is a usb with a live system created copying a file.iso using dd,, maybe the partition table is not present in a live system, im not sure. But this is not the only weird thing about it, gparted sees unallocated space. That is the live i've used to install Utopic Unicorn in another usb. I noticed this behaviour when i experimentally tryed to install systems with 'Kali way of install'. It doesnt really matter, it is almost irrelevant...everything works well so, why bother?
I have another usb not live, it has a installed system inside, copied directly from HD using dd, it's the same: it works fine exept gparted sees unallocated space.

Thought to this: the problem must be bs=
I think appropiate block-size must be in the command line, it should be dd if=/dev/sda of=/dev/sdd bs=512 (or 512x2=1024...or 512x4=2048) until the phisical blocks match the copied block.
