@Bertrand, Essentials models incorporate 128-bit AES hardware encryption. Therefore you will need a functional USB-SATA bridge board.
That said, many users are reporting physical connection problems with the USB connector. If this is your problem, then the most expedient solution would be to find someone to reattach the connector for you.
You can test the connection with Microsoft’s UVCView utility:

If the USB-SATA bridge chip is identifying itself to UVCView, then the most likely culprit is an 8-pin dual MOSFET IC. This IC switches the +5V and +12V power to the HDD. If this chip is faulty, then the simple solution is to snip its pins (with flush cutters), remove it, and replace it with two wire links. This will effectively bypass the switches and cause the drive to be powered on continuously. If you get this far, I can show you exactly what to do. I’ll just need a detailed photo of the board.
BTW, your English is excellent. In fact it is much better than most native English speakers.
