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