Hmm, I will help you if I can. Hard for me to know what you might be doing wrong, or if it will even work with the particular drives you are using.Thx @jcl333 - i tried it, but i got the same error-message.
I know it was a big "WooHoo!" moment when I finally got this to work. I didn't even believe it, plugged it into another controller to confirm.
One thing that helped is for the version of Niagara I downloaded, someone created a bunch of PDF's in the download that showed how to do it, I probably would not have figured it out without that. So thanks to whomever make those ;-)
