Find out the exact size by checking diskutil info on the partition you want to copy. Note: A recovery partition is not always 650002432 bytes. This will repartition your disk, giving us a new partition with exactly enough space for the recovery partition.
Run diskutil resizeVolume disk1s2 Xb JHFS+ Temp 650002432b, replacing X with the total number of bytes from step 2 minus 650002432.Run diskutil info disk1s2 | grep 'Total Size', replacing disk1s2 with the identifier for your external volume.Make note of the identifiers for your existing recovery partition (in my case, disk0s3) and the main partition on your external drive ( disk1s2). You should get output like this: /dev/disk0Ģ: Apple_HFS Macintosh SSD 119.2 GB disk0s2ģ: Apple_Boot Recovery HD 650.0 MB disk0s3 Notes: this process is not destructive, provided you have sufficient free space on your drive.
At least 650 MB of free space on your external drive (a previous version of this answer required more space, but I fixed the first section to only use what's required).Existing recovery partition on your internal drive (or elsewhere).This process worked for me on an external USB drive, but I don't have a Firewire drive or encrypted partition to test with, but it should work for you. dev/disk2ģ: Apple_CoreStorage FreeSpace-500 503.3 GB disk2s3 Note that the (invisible) boot partition created during the process is called Boot OS X, and not Recovery HD. Here, encryption of a partition (FreeSpace-500) has worked directly from Finder. (How) can this be done?ĮDIT: Yes, there is space on the disk for another partition. So I am looking for a way to create a Recovery Partition on the external disk so that I can enable encryption for this disk. This hint is not useful, as it deals with internal disks. Reformatting the drive does create a new RP, but I can’t do this because I have no spare disks where I can swap the data to. Mine does not have one, as it was formatted when there were no Recovery Partitions. Turns out: You need a Recovery Partition (RP) on the external disk you want to encrypt. The disk has been formatted a while ago (2+ years), and when choosing "encrypt volume" from the Finder context menu, Mountain Lion refuses with the message:Ī Recovery system for the targeted disk is required I want to enable encryption on an external FireWire disk.
