OCZ Bootable Toolbox is package that contains a set of bootable tools that can be used with OCZ SSDs.
The tools can be run directly from an USB stick and can be run on OCZ Vertex2, Agility2, Vertex LE, Vertex2 EX, Vertex2 Pro, Vertex3, Agility3, Solid3, Vertex4, Agility4, Octane, OctaneS2, and Petrol SSD drives.
Depending on the firmware revision of your OCZ SSD, some models may have what we call a "destructive update" that is necessary to get to the next firmware level/revision.
If this situation applies to you, you will be warned before the program updates the drive, in order to be prepared.
You can access more information about the toolbox HERE.
NOTE: Even if an update is not destructive it is always recommend to have a backup before attempting any of this.
