title: Trace/BPT trap: 5 error while trying to assign Apple_Boot type to external drive partition
body: <p>I am trying to create a bootable Mac Recovery partition on an external drive. I already cloned the recovery boot from my internal file system, to a partition I made on my external drive. I gave it enough space 5GB.</p>
  
  <p>The problem that I am having now is, after I unmounted it, and entered </p>
  
  <p><code>sudo asr adjust --target /dev/disk2s1 -settype Apple_Boot</code></p>
  
  <p>in terminal to change the type, it refuses to change the type. It just keeps spitting out this </p>
  
  <p><code>Trace/BPT trap: 5</code> </p>
  
  <p>error and I have no idea what thats about. </p>
  
  <p>Like I mentioned, the drive is unmounted. Also, I checked that I have permission to set the type to <code>Apple_Boot</code> . Although, I guess something might be changing it back or something. I don't really know. </p>
  
  <p>Can anyone point me in the right direction please? It would be most appreciated! </p>
