Best Way to Back up Music Library

[gnomus]

Thanks all. This 'fool' just put his brand new 3TB WD drive into his 213J. Unfortunately, I am still getting a blinking orange light and the webpage is telling me that Volume 1 is defective!

Not entirely sure what I should do now. I wonder if the new drive on its own would allow me to have a single disk 213J that actually worked. Any suggestions?
