Warning! firmware update for mavericks kills 'my book studio'

I have posted this already on a different thread on this forum but your actual drive might still be alive. See if any of this sounds familiar:

My case is the ‘Controller Bridge’ seems to be the part that is damaged. If I was able to get hold of one of these then I might be able to access my files. There is a chance the data is still on the drive. My problem now is where to get a ‘Controller Bridge’. Is worth knowing that these drives are encrypted which makes things a whole lot harder:
