What's the difference between WD Discovery and WD Link

On my previous laptop I had both WD Discovery and WD Link software.  On my current laptop I can only find WD Link and am having trouble locating my drive on this current laptop.  The reason I had both on my previous laptop is because a support person at WD told me that WD Discovery was superioor to Wd Link and he gave me the link to the WD software (which I can no longer find), so I’d like to install WD Discovery in the hope it will pick up the new drive on this laptop but cannot find WD Discovery anywhere, can anyone help? Thanks in advance

Here ya go!
