Q: Issues with formating 3TB drive directly in Time Machine app

I bought recently an external 3TB WD Elements USB hard drive for Time Machine backups. Once I connected the drive for the first time, Time Machine asked if I would like to use it for backups. I chose encrypted disk, set the password and let the drive to be prepared. This process took quite long time (≈10 mins), but at the end of it Time Machine complained that it is unable to mount the newly prepared disk (see attached screenshot). However, if I create manually an encrypted HFS+ partition in DiskUtility and then used this partition in Time Machine everything works without issues.

I tried this in two different Macs (both El Capitan) and the same thing occurred.

Mac mini, OS X El Capitan (10.11.3)
