A nice guide from the guys at OCZ. This is for Sandforce based SSD's like the OCZ Vertex2. Not Indilinx drives which use Sanitary Erase. I'd reccomend doing this between Operating System installs to keep it fast and clean.
FOR OCZ SANDFORCE DRIVES IE: Vertex2/LE/Pro, Agility2, and Vertex2/Agility2 EX Drives
