Description of problem:
I think starting with livecd-tools 15.4 I have been getting the following:
livecd-iso-to-disk --resetmbr --format Fedora-Education-Remix.iso /dev/sdd
Fragment sums: 2c2fab2d891f3f67655bfe34cfe49514c2179ee78fe86d3754bb876b9d7a
Fragment count: 20

Version-Release number of selected component (if applicable):
This particular example is with what could be 16.1, but I saw the same message with 15.4 (both the compose and livecd-iso-disk were from 15.4).
Seems to happen all of the time based on small sample set. I don't know if it is in the compose or the check where the problem happens at this point.
Steps to Reproduce:
I check some old images and they show fail now, whereas I am pretty sure they showed pass in the past. So this might just be a livecd-iso-to-disk problem.
Next I'll try to test this by reverting.
I went back to 15.3 and so the same problem, so maybe something else changed. As I am pretty sure I wasn't seeing this previously with 15.3.
I did several installs with F13, F14, F15 TC2 images yesterday and had no failures that I noticed. I did Live and DVD media using v16.1 and just tried them again to be double sure. I suspect your images may be bad.
