You didn't tell if you created a partition yet. We can't format until we have a partition to format.
Sorry but many are not wanting to explore such arcana and I can't tell if this will offend you but tell the forum about the partition creation step.
I have two hard drives. I zeroed one disk. XP windows mode cannot detect the drive. I booted safe mode with prompt. There I could identify the disk but I could not format it. What I could do with that disk?
