On my two Technisatreceivern (Digicorder HD S2 Plus and TechniStar S3 ISIO) was this Intenso Memory Case 500GB unfortunately not recognized. Only a one-time short flashing green and then nothing. Too bad. On this notebook HDD has been detected. I conclude that the HDD needs to start up too much power. My older Seagate Backup Plus Portable STBU1000200 6.4 cm (2.5-inch) External Hard Drive 1TB (USB 3.0) runs smoothly on both receivers.
