Okay, I left the working server for the night, while it was checking the newly connected HDD with Windows integrated utililty (don't know does it do something meaningful )

The device worked the whole night without the problems. At the end it was hot not warm, but I think this is because of some Windows processes which are doing some unknown shi^Wthings on the background

Now, with attached 250 Gb HDD from the shelf, it is ready for #NetBSD , I hope
