How to avoid external hard drive not mounting on Mac You now have a clear idea of how to access an external hard drive on Mac and what to do if it won’t mount. To make sure that you don’t face the same problem in the future, always check that the disk is in the right format for your operating system, that it has a strong enough power supply. Shutdown your Mac, unplug it if it is a desktop. Unplug the WD Passport. Boot it up and then plug in the drive. If it still won't mount, then reboot but do CMD+OPT+P+R to reset PRAM. Try mounting again. The recent Western Digital 'easy store' and 'My Book' hard drives have a Mac Sierra 10.12.6 issue: They are invisible to the Desktop. WD Utilities says my two drives check out ok; Mac Utilities recognizes both hard drives. Going to the Mac Genius Bar on Monday. BestBuy sold me the original WD easystore 8T and WD sent me a My Book 8T. The WD Passport Ultra was plugged into my MacBook on battery. I was not actively reading or writing to the external hard drive, but it did have a list of directories open (no individual photo files, but just the directory names). The battery ran out. When I charged up my Mac again it says that the disk was not ejected properly.
