I have a Mac 2012 model with MacOS Sierra 10.12 installed on it.
I recently bought a 4Tb drive as I try to keep my media seperate from the main computer. My problem cropped up recently where the drive still shows on the desktop but when I click on it, finder will show nothing. This is after the computer has not been used for a while and may have gone down to sleep mode. I need to unplug the drive and replug it in and the contents will show up again with no issues. I do have another WD drive attached to the same computer and it does NOT have the same issue, so it seems like it is only with respect to this 4Tb drive. I have tried running WD Drive utilities on it for the Mac and it shows the Smart has passed and that the drive after a quick scan at least is ok.
I was wondering if this is a firmware issue? Or could it be a MacOS Sierra issue since the drive is a 4Tb drive. the 4Tb drive is formatted with HFS format.
Any clues would help. Thanks
