class Me {
  public Data salvageDataFromBrokenPC(PC brokenPC){
    HDD hdd = brokenPC.getHDD();
    HDDEnclosure enclosure = buy(HDDEnclosure.class);
    enclosure.setHDD(hdd);
    return enclosure.getData();
  }
}

Exception in thread "main" java.lang.Exception: 
           Can't set IDE HDD to eSATA HDD Enclosure
