I have only been testing Type 3 with scsi_debug (which conveniently
avoids the formatting step).
I doubt we will see any disk drives that support Type 3. The way the
standard is written, a drive can either do Type 1+2 or Type 1+3. Type
2+3 is not a possible combination.
In any case. If you happen to own a Type 3-capable device you format
it exactly like if it had been a Type 2. I.e. set PINFO=1 and
RTO_REQ=1 in FORMAT UNIT. sg_format can already do this.
