My computer is full and my new external harddrive just came in the mail (WD Passport). I am having a hard time formatting for mac, keep getting this message: Partition failed with the error: Couldn't unmount disk

 

SMART status not supported.

Partition Map Scheme: master boot record

 

It there something wrong with the drive?

 

Thank you!
