   Hi all,   
   many thanks for all your hints!   
      
   In the meantime I found more adapters here and accomplished some more   
   tests.   
      
   Just to summarize -- I found the following:   
      
   - both, Samsung EVO 840 and 870 can be fully accessed by hdparm through   
   USB   
      
   - both, Samsung EVO 840 and 870 do have a built-in master password (which   
   should be overwritten prior to use)   
      
   - USB-to-SATA adapters from "Logilink" do or do not work. At least, this   
   one does not support HPA and other hdparm features: SN 39993001701   
      
   - Renkforce "SATA Docking Station Cloner" is fully supporting hdparm   
   command set. So, whenever a machine has to be equipped with a new SSD   
   that has a master password, and the machine does not allow to disable it   
   in the BIOS, the password can be set this way.   
      
   So, once again, thanks for all your ideas!   
      
   Best regards,   
      
   Markus
