My Passport Essential SE Doesn't show Any data on Home or Backup Screen

I’ve had My Passport Essential SE for a few days.  There is data on the drive but suddenly nothing is showing on the Home or Backup tabs.  They show 0 files and 0 size.  They did show the backed up data yesterday.

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
