You have to do that at provisioning time in the drive. Ie, once you
layer a file system on it, the drive doesn't know what's "empty" and
what's not; you have to tell it before hand that only show X% to the
system, and keep the rest for wear leveling. I don't know the tools
for doing it, as my vendor takes care of that for me.
