Time Machine - there was an error preparing the Time Machine backup drive (could not mount the drive)

I have a new HD but cannot set up encryption with system preferences. After ten minutes, I get the following error message:

"There was an error preparing the Time Machine backup disk (disc name) - could not mount drive"

Apparently, I need to set up the HD in this way:

  • If you are using an external drive connected to your Mac, use disk utility to make sure that your backup disk is formatted in HFS + extended (journaled) and is the partition type GUID Partition Table (GPT)

It is not an option for the HFS + and so I used; OS x EXTENDED (journaled). GUID is ok.

Can someone let me know what I need to do.

Thank you

Formatting: GUID Partition Table, OS X Extended (journaled).    (it is HFS +)

For TimeMachine at best to a partition only.

Do it again if necessary, then disconnect, reconnect, Start Time Machine preferences and "select disk".
