Only a handfull of files seem to have a problem, so for now I will leave as 
it. I guess I could try deleting those files.

Will do. I will setup another VM. The original data was downloaded over DSL 
and took almost a week to download.

Where can I read about how to do that?

Also, is the crash possibly due to the fact it is in a VM? This is my first 
production test of DragonFly, so I am trying to understand what happened. If 
this was a sever with original data, I would be pretty worried about the 
data.
