I have a WD MyBookWorld Edition 1TB White Light. I have used it for about 4 years. It is attached by ethernet to my router and I have my early 2011 MaBookPro set up to back up to the WD using Time Machine. I also save some documents to the WD in the public folder.
In the Finder app I can usually connect to the WD drive and assess my public folder where I store some documents, but Time Machine is hit and miss. Most often it can not find the WD_Backup folder, or can not connect for Time Machine (even if I can see the folder in Finder).
Lately the WD drive has not even been showing in Finder at all. i.e. it will connect and then later when I look again it will have vanished.
What I have tried:
I currenty have the WD plugged into my MacBookPro via ethernet to eliminate any wifi issues.
I have tried reseting the WD by putting a pin in the back. I have also turned it off and on again. Last night I tried deleting the sparsebundle file so that the disk is empty for me to start a fresh new Time Machine connection. That worked but the Time Machine failed to complete a new back up and I cant see the WD in Finder now.
I would like to fully restore the WD drive to it’s original (empty) state and start afresh. Can anyone advise the best/simplest way of doing this. And also advise how to Find the WD in Finder when it vanishes?
