Interesting that it doesn't show partitions type id like it 
does for a dos partition scheme. Also, know dos partition 
sceem only support 4 primary partitions, but gpt probable 
does have that limit??
With dos, you can have 3 primary and then a primary that 
is an extended partition and it can then have a bunch of 
logical partition.

Once had my computer lab at college get 20 new 
machines all identical. But one had disk show as slightly 
smaller due to bad sectores. Used that machine to image 
to all the others since direct clone works copying a 
smaller disk to a larger one. 

Not doing more than basic testing with gpt, you might 
want to resize the C: and then move the 4th partition to 
next to it. 

Good Luck.
