Hi,
I don’t think the QU-16 recognizes partitions, because A & H recommends formatting a drive for use only with the QU-16. Fat-32 format, I believe. They specify a only certain drives as being compatible. See this link for more info:

Sorry, I really don’t know about the QU recognizing partitions, my guess is that it won’t recognize partitions. I just followed their recommendation for getting a drive just for use with the mixer, formatting the drive using the mixer, so it also builds the right folder structure, etc and then after the gig, xferring all the audio files to my computer @ home.
Hope this helps..
John
