One more time, you did install a working drive in your new enclosure correct? Have you used the search function I outlined? If you have a valid functioning hard drive in the enclosure it should be showing up.
Another option depending on your PC is just open it, find an open HDD port and temporarily connect your old HDD assuming it works. Power it using any SATA connectors unused from your PSU. This should not be complicated.
Also on a side note why are you posting pictures rather than screen shots?
