Have you used the MBL much before you attached the Sonos? Have you streamed music from the MBL to a computer or something else before you got the Sonos? The tests you are running, please do not have the Sonos plugged in. You need to determine what exactly is the root problem here. By introducing the Sonos, you are adding an extra variable to the situation unecessarily. Before you attempt to do surgery on the MBL, you need to make sure that the problem is not your Sonos.
You say that the light on your MBL is white now. Can you hear the drives spinning? or is it quiet? You didn’t say in your prior message if you pushed the reset button or not last time.
Please do the process again. Unplug the ethernet cable from the MBL. Wait until it turns blue. If after 3 days it is not blue, then unplug the power supply and reboot it manually (plug back in power supply). Wait until the light turns blue. Do the reset button. Wait till blue again. Then plug in the ethernet cable. NO SONOS - get that off your network. Then try to access the MBL web-interface with your PC. Look at the condition of the drive. It should tell you if there is any problems. Do a factory reinstall. This will remove all your data. When it is all finished, put 10 songs on your MBL. Play those songs by streaming them to your computer. Make sure the songs are an accurate sample of the file types you have on the MBL now. See what happens. If all is good, then try with the Sonos.
The trick with all this troubleshooting is to be methodical. To try to eliminate every possible variable before you introduce a new variable.
If you can’t get the MBL to go to a blue light at all, then you have two choices. 1) return it to WD for service. 2) surgery.
Surgery means that you take the drive out of the box, attach it to a PC running LInux with a SATA cable, and run a script to rebuild the O/S on the MBL. There are guides on how to do this on this forum. see this thread for some links at teh bottom

You might have a faulty drive with bad sectors. So that might be something to check out also.
