My Book Essential 3TB Doesn't work with Storage Spaces

I tried to add this disk to storage spaces, it shows up in the add drive wizard list in the formatted section (but with no details). Once I check it and continue, it gives the following error:

Can’t Prepare drives

Close all applications that are accessing this drive and then try again

Details are: The system cannot find the drive specified (0x000000f)

I’ve updated the firmware and still no luck…formatted the drive, added and removed it, tried it with different partitions, gpt and mbr, formatted and not…still doesn’t work…

Any ideas?

Not sure if this new feature is yet supported

try contacting WD directly
