Q: Can i use file vault on second hard drive in machine.  Use SSD for OS and apps but data stored on second hard drive

OS Yosemite 10.10.4 on 15 inch Macbook Pro, Mid 2012.  16 gbytes memory and 2.7 Ghtz Intel I7

 

the systems is configured with a SSD where the OS and Apps are stored.  The machines boots form the SSD.  A second 800 GB hard drive replaced the CD.  FIlevault is turned on to protect the SSD but need to protect the hard drive as well.  Can file vault be extended to cover second internal Hard Drive?  If not what is a good solution to encrypt the second hard drive?

    Hi !

     

    Filevault does not work on external hard drives.Although you have it inside, it is considered an external hard drive.External here means " not system hard drive".

     

    Solution nø1 : bad solution (applies to external drives that you want to protect with Mac OS password)

     

    Right click (or ctrl click) on the 2nd hard drive and select "encrypt ".

     

    Now, you will face two problems :

    If the user and datas are on the 2nd hard drive, it will have to be unencrypted before use.(login)

    But to be unencrypted, you" ll have to store the encryption password in user keychain thus you" ll have to be logged in first...

     

    Solution nø2 :good solution (in your case)

     

    So, you'd better backup everything (time machine) on a "real" external drive, erase hard drives, create a fusion drive with the two drives, install Mac OS, migrate your data, and afterwards, enable Filevault.

     

    Do not forget to backup

     

    Cheers-
