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.
The problem that I am having now is, after I unmounted it, and entered
sudo asr adjust --target /dev/disk2s1 -settype Apple_Boot
in terminal to change the type, it refuses to change the type. It just keeps spitting out this
Trace/BPT trap: 5
error and I have no idea what thats about.
Like I mentioned, the drive is unmounted. Also, I checked that I have permission to set the type to Apple_Boot . Although, I guess something might be changing it back or something. I don't really know.
Can anyone point me in the right direction please? It would be most appreciated!

我认为这是一个硬件问题。我使用闪存驱动器代替外部驱动器并且工作正常。
