Thanks for this. I tried a hundred other solutions with diskutil and diskutil cs, but none of the operations completed successfully. Zeroing out the volume with dd was the only way to nuke it sufficiently to be able to reformat it as a non-fusion drive.

| Aug 2, 2012 at 6:27 | comment | added | bahamat | That will also destroy your recovery partition. If you have an external disk to boot from (or a newer Mac that will netboot over the Internet) then yes it's safe. You just need to re-partition afterward. | |
