That won't work for my application.

I'm trying to fill a hard drive with all ones.  I know how to fill it
with all zeros:

dd if=/dev/zero of=/dev/hdb bs=1024 count=58615704

I don't know how to fill it with all ones.

I'm working within pretty low functionality on this system (RHL 9
installation CD rescue mode)

Thanks,
William
