Hello,
I have installed the WD with me.
If you install the SSD, you have to wait a bit longer,
but your Audya boots up later.
Only then comes the message that the SSD must be formatted.
At first I also thought that it did not work.
The Audya bottet also without HD / SSD.
For me it was like that,
you have to format the SSD in any case in your Audya.
So install and wait a little longer.
I hope that it works, if the SSD is recognized as a hard drive, you get a message and format it.
Then expand again and copy your HD on it.
Unfortunately, cloning did not work for me.
But everything is going great, even the LED's as before, only a little faster.
Hope it works with your SSD.
