I don't have the spec right here. I think it amounts to (with the
scsi -f /dev/rsd0.ctl -e 3 -P 3 # Manually edit the format
# device page to set sector size.
scsi -f /dev/rsd0.ctl -c "4 0 0 0 0 0" # Format.
"-P 3" select parameter set 3, the permanent ones.
The .ctl device bypasses everything and responds to the ioctl so
a really dead drive can be formatted, plus you can protect it carefully.
It usually isn't needed as long as something responds to the ioctl.
If you have the SCSI spec, the "-c" option lets you send what you want to
from the command line.
