Actually that's something I already tried, If i take it out it fails
with something like "disk write error: invalid arguement" similar to the
ccdconfig :) It seems any call to bwrite fails when the drive is
larger than 1TB. (which is why -N seems to work with no issues, calls
wtfs which doesnt call bwrite when the Nflag is set)
