Do you hear it?
No, I heard nothing, but I might not have heard the spin-up noise because the enclosure needed to be placed behind the desktop tower because its cables were so short. As for the noise of the heads, there was none, probably because the operating system never saw the disk so never tried to read the disk. However, I just achieved a breakthrough by discovering an astonishing cause to the problem. I will post this as a reply (labeled "maybe solved") to to my original post.
