I wish to encrypt my WD My Passport Pro drive. I receive error

enter image description here

With Google I found

An error message occurs when attempting to create an encrypted backup on a My Book Thunderbolt Duo in the Mac OSX 10.7.x (Lion) or 10.8.x (Mountain Lion) Operating System (OS).

In 10.7.x, the error states You can't convert an AppleRAID volume to Core Storage.
In 10.8.x, the error states There was an error preparing the Time machine backup disk 'My Book Thunderbolt Duo'.

I don't like their solution

Do not enable Encrypt backup disk on the Time Machine Select Disk screen in Lion or Mountain Lion OSX with a My Book Thunderbolt Duo.

this is the RAID config

I already have data there. Howto encrypt this drive online?

  • By online, you mean finding information online on encrypting it or having some other software encrypt it? Apr 3, 2016 at 23:17
  • i mean without downtime and data loss
