MacBook doesn't read WD 2TB Exterrnal

Opened up my WD 2 TB external hard drive, plugged it in and it was working. Decided to use the time machine feature of my Mac and NOW the External is “unrecognizable.” Anyone have any solutions before I call WD for a new one?

Is the hard drive detected within Disk Utility after disconnecting it from the power adapter and rebooting your Mac?

Yes, i see it on the disk utility screen in the “external” section.

I am having this same problem. I will be following for answers. Thank you
