In preparation for Mt. Lion, I thought I would Erase Free Space. But I am unable to do so.
After launching Disk Utilities and initiating the requisite action, I am always advised that the erase could not be done because: “Some information was unavailable during an internal lookup.â€
This happens on all internal and external volumes.
I thought that maybe some third-party app/plugin was at play, so I attempted same while in in Safe Boot. Again, no joy.
Now I don’t know what to do. Any suggestions?
