When trying to install 10.8 (Booting from a key) I encountered an error and assumed that it was caused by my FileVault volume.

There was only one hard drive (SSD, 256Gb), and one volume on it encrypted with FileVault 2, so I decrypted it using the preference pan, and installed 10.8 Lion (After reseting the PRAM, there was my previous issue).

 

Now that 10.8 is installed I want to re-encrypt my SSD but when I try to activate it back again, the preference pan tells me that

 

FileVault Failed The target Core Storage volume is already encrypted.

 

and diskutil in command line tells me :

 

macbook-air:~ someone$ diskutil cs decryptVolume 9D59BA0A-0F9B-499D-9B0B-77397FB8D5F1

Passphrase:

Error beginning CoreStorage Logical Volume decryption: The target Core Storage volume is not encrypted (-69755)

 

One is telling me that the volume is already encrypted (but the password is prompted at login time, not by the EFI as it should if it was crypted).

And the other is telling me that it's not crypted.

 

When I try to encrypt using command line, it gets ridiculous

 

macbook-air:~ someone$ diskutil cs decryptVolume 9D59BA0A-0F9B-499D-9B0B-77397FB8D5F1

Passphrase:

Error beginning CoreStorage Logical Volume decryption: The target Core Storage volume is not encrypted (-69755)

 

macbook-air:~ someone$ diskutil cs encryptVolume 9D59BA0A-0F9B-499D-9B0B-77397FB8D5F1

New passphrase for existing volume:

Confirm new passphrase:

Started CoreStorage operation on disk1 SSD

Error: -69696: The target Core Storage volume is already encrypted

 

I guess there is some kind of bug, any idea how to circumvent it ?

Thanks.

    I just solved the issue above by rebooting on the installation key, and using Disk Utility to « Repair the disk », which apparently changed some boot information as it said it did in the log window.

     

    Everything works fine now and the preference pan accepted to encrypt the volume again after a formal reboot.

    I'm amazed to see that the only two problems I encoutered this year with this Mac have been solved by common maintenance and well known operations (PRAM reset and now Disk repair).

    Hey Gribouille,

    I'm having a similar, I thought you may be able to help me out, since I couldn't figure it out myself and nothing came upin google search.

     

    I'm using an early 2011 MBP, OS X 10.8.3 and a LaCie 2TB external HDD.

    here's the problem:

    I wanted to try and encrypt my external hdd for the first time, so I did it by right clicking on the drive and setting up a password, and then as I didn't want it to still be encrypted I decrypted it. But now when i'm trying to encrypting it again it says: "The target Core Storage volume is already encrypted.", although it doesn't require password and when I go to disk utility>File> the "change password" is not highlighted (meaning that it doesn't have a password). on the other hand when I go to "Get Info" of the drive in the format it says: Mac OS Extended (Journaled, Encrypted).

    Do you have any suggestions to fix the problem?

     

    By the way I have a very precious 1.7 TB data on the drive and I don't want to risk losing them in the process, and as I'm relatively new to Mac please explain step by step (for example I have no idea about the stuff in the grey boxes you've written above).

     

    P.S. I tried repairing the disk from disk utility and rebooting my laptop, but that didn't work.

     

    Thanks in advance.

    kioomars, have you tried a simple reboot? I also ran into the "The target core storage volume is already encrypted" error message. A simple reboot and re-try allowed me to bypass that error.

     

    EDIT: Sorry, I just noticed you already tried a reboot.

  • kioomars Level 1 Level 1 (0 points)

    Hey Drew,

    rebooting didn't help either.

    I also need to access this drive on windows, I installed MacDrive and it was working, but after the encrypting and decrypting the drive on my mac, my pc doesn't recognize it! Do you think it's also because of the same problem I'm having with re-encrypting?

  • kioomars Level 1 Level 1 (0 points)

    Just wanted to inform you the problem's gone somehow without me doing anything!
