file as a
logical device, then FORMAT or INIT it, or do a COPY/DEV
to it...
Use PIP to do a absolute block addressed copy. I think it's :n or :I
and your can then move known clear blocks to anywhere on the disk.
I think you're talking about RT-11, Allison, but I may be wrong because
the utility name you specify and the options you're talking about make
no sense under RT-11. Are you maybe talking about some other OS?
Under RT-11, it's not PIP, it's DUP, and the option is /G:n.
The CCL equivalent is COPY/FILE/DEVICE/START:n.
If you have to do that alot under RT-11 make up a disk
with files that
contain nothingg (fresh disk) but use the entire surface and then image
copy it.
Or, even easier, just do an FORMAT/VERIFY:ONLY. To be really thorough,
do a FORMAT/VERIFY:ONLY/PATT:7777 to write 12 different patterns over
the disk.
