Hyper-V export VHD, is it really an exact copy?

I've exported a 100 Gb Hyper-V virtual to a USB drive from a Small Business Server 2011 Standard Host after stopping the virtual and when I compare the SHA-1 Hash of the original .VHD file to that of the exported .VHD file on the USB drive they are not the same, although the files are the same size.  

Is the claim that the VHD file in the export is "the same" accurate?

My choices seem to be:

1.  Have confidence that the USB export can be imported and booted in the future.  I do not have the resources to test this right now.

2.  Export the virtual again until the hashes agree.

3.  Copy the VHD file until the hashes agree.  I'm trying this but would like to know if it's a reasonable thing to do . . . it takes a while to copy and rehash.

I'm using HashTab ver 4.0.0 from Implbits (originally and have used this and three earlier versions in the past with excellent results.

So is "the same" really identical in this case, or not?
