I am selling my iMac. I want to erase my personal data from the computer but I keep getting an error:

Secure Disk Erase Failed

Secure disk failed with an error:

couldn't unmount disk.

According to this fourm http://forums.macrumors.com/showthread.php?t=1236267 it appears to be a bug in Loin. Does anyone know how to fix this?
