Is this at all possible? My BIOS don't seem to recognize my brand new 200
GB disk, but that is nothing new. I can initialize a new slize, setup
bsdlabel and do newfs on if without problems. How can I verify that the
entire disk is usable without filling it all up (or past the 128 GiB
barrier), and then reading everything back out?
