I am about to purchase a Western Digital my book 2 NAS. My current set up is PC with an external hard drive (maxtor) that stores my music. Obviously my PC ( and maxtor) has to be on to play my stored music via SONOS, hence the NAS purchase. I assume i just plug in the NAS to my router. The router also has a zonebridge attached. How do i transfer my music from the maxtor to the NAS - is it as simple as copy and paste. I will be throwing away my PC after the transfer and will just use my lap top. Thanks, Dan
