for those of you attempting to "Erase Free Space" per knowledge base article:
"OS X Lion v10.7.3: User account passwords appear in log files for Legacy FileVault, and/or network home directories"

 

quote:
"6. Open Disk Utility.

7. Select your OS X Lion volume on the left.

8. Click "Erase Free Space…".

9. Select the Erase Free Space Option you want and click "Erase Free Space". Enter admin name and password if prompted."

 

but instead seeing a grayed out "Erase Free Space" in Disk Utility?

 

you can perform an "Erase Free Space" by using WipeFS app by Jonathan Clark which can successfully perform a DoD (Department of Defense) wipe for digital media, apple's Disk Utility doesn't do this anymore with non-apple solid state drives (ssd)
