I could be wrong on this but maybe someone on this list can answer it. You will need to know some basic info on my SONOS system so I posted below..
I mostly use my personal music library that is located on a solid state drive via my ethernet wifi connected network. I have a Apple Ethernet-wi-fi router that has an USB input on it. My SS drive with over 39,000 tracks on it (also my Apple itunes AKA Music drive) is connected to that same router. My SONOS components grab my music from that SS drive.
With this upcoming software update it sounds like I (anyone with a similar hook up) will lose access to their connected drives??? I will lose of all my own paid for music on that drive. So one questions since I’m not quite a computer nut is… Is the way I have my SS drive connected to the router via USB considered a NAS drive?? Will I lose access to that drive if I do the update?
