So last night, I went home and attempted to reconnect my MY Book to my Imac - and luckily i was able to get it to mount.
i think this is just dumb luck - as i have been able to get it to mount before, but then it becomes unresponsive and disappears from my desktop.
So once it was mounted, I followed the onine instructions to update the firmware and install WD device manager on my Mac.
Once this whole process was completed, the drive seemed to actually be stable. I was able to play files from, and transfer files on and off.
Before I went to bed, I set it up to transfer about 400GB off of it, in order to salvage my files in case the drive died again.
Sure enough, when I awoke this morning, I had an error message pertaining to one of my files - saying that it could not be copied. This of course had stalled the transfer of all other files behind it. Once I bypassed the error message, the WD drive was again unresponsive.
It was still mounted to the desktop, but I could not access any files on it or anything.
The light on the front was lightly fading on and off.
I rebooted my iMac, only to find that the WD drive now would not mount at all . . . . the light on the front is now back to moving up and down as if it is trying to get it’s bearings (same thing it was doing before all of this)
I am literally right back were i started . . . .
