No, file stays the same

The modules it tries to move are commented out!

I'm beginning to think there may be something more going on here. If I 
re-start the process (re-format the disk, write the new image, etc) it 
fails in new and interesting ways. Never the same way twice. Sometimes 
it appears to dump out the contents of the standard.bl file.

Either my method is incorrect or there may be some sort of hardware 
issue in play here. Maybe these disk images aren't being written 
correctly and are corrupted.

I tried this with a clean image and didn't modify anything- it actually 
built the disk. Once.
