Hi, Just purchased WD Elements 3TB portable , I’m using a Mac book pro Touch Bar, latest High Sierra operating system. When I connect the disk utility give s the unreadable message, the drive is also greyed out. when highlighted I’ve tried erasing and first aid, please see screen shots. Does anyone have a fix for this
It’s a feature. It took me a while to figure this one out and … it’s a problem of the new Macs, I used two different Macs. You can reformat it on an older Mac but not the new ones. As an FYI the new file format, APFS, for High Sierra IS NOT compatible with Time Machine from what I’ve been reading. Does it work on a High Sierra Mac after formatting…YES.
Thanks Ken, i’ve Also requested support directly from WD, awaiting their response. I have also tried formatting on my iMac and get the same messages.
We have resolved please see below
