The drive says there is 3.63TB out of 3.63TB (4TB Drive) available but when I run WD Backup and point it to a drive that is 2.72TB in size, the WD Backup program complains and says:
Unable to back up files to My Passport Ultra because there is not enough space.
The 3TB external drive I am trying to back up has 388GB of free space.
Any idas?
