Q: No 1. I can not activate Filevault : FileVault can’t be turned on for the disk “Macintosh HD”. Some disk formats don’t support the recovery partition required by encryption. To use encryption, reinstall this version of Mac OS X on a reformatted disk.

I have TWO PROBLEMS

No 1. I can not activate FileVault. It displyas as follows :

FileVault can’t be turned on for the disk “Macintosh HD”.

Some disk formats don’t support the recovery partition required by encryption. To use encryption, reinstall this version of Mac OS X on a reformatted disk.

No 2. I can not activate Find My Mac service. It displays as follows :

Find My Mac requires a recovery partition

Some configurations, such as software or hardware RAID, do not support a recovery partition and can't be used with find my mac

MacBook Pro, OS X Mountain Lion (10.8.5)

I have OS X 10.9.1 in my MBP. Do I have to creat Recovery Partition ? Let me inform you that I made own Bootable USB Drive for OS X mavericks and installed Mavericks in my MBP. The mavericks is not upgraded one. If still I have to creat Recovery Partition, Then how can I creat it without reinstilling OS X Mav. If I have to creat Recovery Partition, I would like to creat it in Macintosh HD, not in external Hard Disk.

Based on the 2 problems you are trying to resolve, it appears you need a Recovery Partition. The first 2 links suggest how to do that.

Glad you got it running but that was the problem. You can not enable filevault with out the recovery partition and the re install was able to lay down the recovery partition the 2nd time around.

What amazes me in this story is the inadequate error message. In fact it is not about a wrong file system or the long way of re-installing the OS. All you need to do is to run the Recovery partition. It happens to me for the second time.
