Both are a function of the SCSI drive itself. You have to (de)select
it by setting the appropriate bit(s) in the drives modepages. 

Doing so take something like SCSICNTRL.EXE an unsupported tool from
Adaptec that runs on top of a ASPI compliant driver.

Maybe there is also a way to do it using FreeBSD, but I dunno.

Maybe the sectors contain only filesystem metadata for as of yet
unused data areas??
