title: Vagrant corrupted index file C:\Users\USERNAME\.vagrant.d/data/machine-index/index
body: <p>My Windows 8.1 just crashed. Now I have some files on my dist that are corrupted. This includes my vagrant machine index (Not shure if the naming is right but I know that it is this file -> C:\Users\USERNAME.vagrant.d/data/machine-index/index).</p>
  
  <p>So There is a lot of binary or hexdecimal stuff in there (Again not shure because I don't deal with this stuff usualy so correct me if I'm wrong!) And Vagrant spits out the following message if I try to start everything after boot.</p>
  
  <p><code>vagrant up</code> returns this</p>
  
  <pre><code>The machine index which stores all required information about
  running Vagrant environments has become corrupt. This is usually
  caused by external tampering of the Vagrant data folder.
  
  Vagrant cannot manage any Vagrant environments if the index is
  corrupt. Please attempt to manually correct it. If you are unable
  to manually correct it, then remove the data file at the path below.
  This will leave all existing Vagrant environments "orphaned" and
  they'll have to be destroyed manually.
  
  Path: C:/Users/Username/.vagrant.d/data/machine-index/index
