I never heard of a Samsung HDD so I actually looked into this but couldn't find one in my spares box and the controller board footprint was different from any WD or Seagate or even a Maxtor drive I had. the diode trick worked for me, the drive would not even spool up and would send anything I used for power into protection. Media was crystal clean inside, no crashes evident (if you could see them at all nowadays on a 1TB drive) I tried Linux to access this drive as Windows didnt see it as initialized, then CRC error, then just tossed it. Nothing left on it that was important to me.
