I purchased a My Book Mac 3TB to compliment my new 2013 MacPro since it has limited internal storage.
I noticed that I have periodic freezes when there’s access to the My Book, the whole computer freezes.
I have to reboot the whole computer for it to restart.
I have another external hard drive with an SSD that I’ve mounted my ~/ home folder to, which gets much more R/W access than the My Book over USB3 also.
I thought it may be a problem with USB3 but the other drive works flawlessly.
I’m asking for help on the forum before I scrap this drive , post my experience with WD My Book Mac on Amazon Reveiews , and purchase an different manufacturers external hard drive.
