The tools I have can only revive the drive with a fresh low-level format, erasing everything. They cannot make existing data accessible again.

I don't have any OCZ -2 series drives here now, but somewhere on them, either external or internal, is a two-pin header. When jumpered, this enables the failsafe bootblock, causing the drive to become visible again to the host system. Usually as a "32GB SSD" or something. The factory tools can then reflash correct firmware and do the low-level reformat of the flash sectors.

Cheers
