I have done it with
dd if=/dev/zero of=newdisk.dsk bs=1k count=10240
to make 10MB RL02 images. Followed by the lightly-documented
step in the Supnik emulator of attaching the disk image and writing
the badblock table. Followed by (for RT11) INIT/NOQ DL1
Corresponding for a Unix system would be mkfs(8) or newfs(8),
whichever you have.
I think it is only the RL disks that need the badblock step.
