I’ve had a 3TB My Book Live set up as my back up. I created a Z drive and everything seemed to be working well until recently.
I’ve spoken with WD Support several times and they’ve tried to help me through mapping the network drive again. It doesn’t seem to work. I use Windows 10.
The technician suggested I reset the machine and wait for the green light to stop blinking. He said the reset process could take a week or more.
The green light has gone solid a few times but by the time I get to call WD Support it’s back to blinking again.
A week or more sounds a bit unreasonable, but a “Full Factory Restore” reset takes many, many hours. The amount of time depends on the size of the drive because all data is erased.
Make sure that Windows did not change your sharing settings. In particular, make sure you current profile is “Private”. Windows will switch your adapter to one of the more restrictive profiles if you change routers (for instance).
Make sure Windows did not change your NetBIOS over TCP/IP capability. If you are using the default setting of “Auto” Windows will sometimes disable the capability. (The only documented reason I’ve seen is if you use static IP addresses, but I’ve seen reports of it’s being disabled for other, less clear, reasons.)
