I'm not sure how they're physically done. I didn't even know of them
until I started I started writing my backup script. I just saw this
from the mt man page on our HPUX box:

           smk       Write count setmarks (DDS drives only).

           fss       Forward space count setmarks (DDS drives only).

           bss       Backward space count setmarks (DDS drives only).

and it did just what I wanted it to.
