diskdrives do neither need nor want: -O create a 4.3BSD format filesystem -d rotational delay between contiguous blocks -k sector 0 skew, per track -l hardware sector interleave -n number of distinguished rotational positions -p spare sectors per track -r revolutions/minute -t tracks/cylinder -x spare sectors per cylinder No change in the produced filesystem image unless one or more of these options were used.
