Restore the data from a backup. Helpful (0) Reply options Link to this post This site contains user submitted content, comments and opinions and is for informational purposes only.

2 encrypted drives while booted from Mavericks' RecoveryHD August 12, 2014 rtrouton Leave a comment Go to comments While working with a colleague to prepare a FileVault 2 rollout at his institution, he reported that in his testing, the decryption process did not appear to be working correctly when he was booted from the Recovery HD partition and using the command line diskutil-based decryption procedure that I had posted. In his testing, he was finding that the CoreStorage volume that the FileVault 2 encryption process created was not being removed when the diskutil corestorage revert command was run. The drive was being decrypted, but the CoreStorage volume was being left behind. This caused problems in his testing, because he found that rebooting afterwards led to the Mac booting to a prohibited sign. This symbol at boot means the system has found a bootable installation of Mac OS X on the system, but there is something wrong with it. After some additional testing, he discovered that he actually needed to run diskutil corestorage revert twice in succession. Running diskutil corestorage revert the first time would decrypt the drive. Running diskutil corestorage revert a second time following the first command would then remove the unencrypted CoreStorage volume. Once the CoreStorage volume was removed, the Mac would then be able to reboot normally to the regular boot drive. The behavior seems to be tied to the following: 1. Booting from a Mavericks Recovery HD partition (all testing was done with a 10.9.4 Recovery HD partition.) 2. Decrypting either of the following methods: A. Using Recovery HD‘s Disk Utility to decrypt the FileVault 2-encrypted boot drive. This decryption method is described here. B. Running diskutil corestorage -revert from the Terminal. This decryption method is described here. 3. Letting the drive get to Conv
