My Passport stops backing up


I have a new My Passport Essential SE 750 GB drive.  I reformatted it for Mac OS X, and am trying to back up my computer to it, but whether I use Time Machine, WD SmartWare, or manually transfer files, it transfers some files and then seems to eject the disk and stop backing up files.  I’ve tried quitting all other applications (is this really necessary?), and it still does this.  Any ideas?

Thank you!

I am having the same problem and have been for months. If you find an answer, please share with me :slight_smile:

Did you try to contact WD for help?
