I had the same question last week when I called in. The tech said it would work, I asked are you sure, he said others said it worked then looked at the web site and said the supported device was pro-hd. He told me to go buy s WD at Best Buy and try it, if it didn't work I should take the WD back. I bought one and now getting error that I need to load the latest firmware, which I already have.
First of all I have been a loyal customer since 2007. I have a pro and also a catcher and other apps. Would be nice if someone within the company could answer.
Can anyone comment?
