Cannot turn on FileVault 2: "some disc formats do not support the recovery partition" version of the OS - 10.11.4

Hello

I went to turn on FileVault encryption for the first time, and when I click on restart (by FileVault guests) I got a error message that says "FileVault can not be enabled for the drive. Some disc formats do not support the required encryption recovery partition. To use encryption, reinstall this version of Mac OS x on a reformatted drive. »

I found an article from apple support for this problem with El Capitan who recommended first aid running in disk utility.  I tried this but then received the same error message.

a little history:

-Mac OS 10.11.4 installed running on the brand/model ADATA SP 550 SSD

-This SSD is a 250 GB drive partitioned into two, with one of these partitions being my OS

-J' ran this BONE of a Bay external thunderbolt

-ssd is formatted as HFS journaling +.

I am really confused about this error message and couldn't find much online about it.  I use a fairly recent OS install.  I installed the operating system clean and made all my preferences and install so that I can encrypt and then back up this pristine OS environment in time machine so that I could always go back to it on the line in case where things are bunk too upward.  I'd have to install yet another OS to clean and do all my long software installs and system preferences settings... SIP.  I don't know if that makes a difference, but this version of the OS that I have been cloned by superduper to this SSD partition.

What is the brand of SSD that I?  Might that matter?  I appreciate all the comments.  I'm really scratching my head...

Thank you very much

To enable FileVault, you need a recovery partition, which you don't have. You can create one by reinstalling OS X.

If you do not already have a current backup, please backup all data, and then reinstall the OS. * you don't need to erase the boot volume, and you won't need the backup unless something is wrong. If the system has been upgraded an earlier version of Mac OS X, you may need to the Apple ID and password to use.

There are ways to back up a computer that is not fully functional. Ask if you need advice.

If you installed the runtime Java distributed by Apple, and still need, you will need to reinstall it. It goes the same for Xcode. All other data will be preserved.

Related support article refers to OS X 10.11 ("El Capitan"), but the procedure is the same for OS X 10.7 ("Lion") and later versions.
