It has to be some problem with the missing stuff from the CD which I got with the SSD.
I have 3 x Samsung SSD's. One of them, an 850EVO 500GB,
exactly like yours. There is nothing on that CD that would do this or fix this.
But, you can download what you like, direct from Samsung.

Possibly you need the latest firmware, but that is not the problem here.
