This should help: http://www.techhack.co.uk/2011/03/31/format-a-hard-drive-with-command-prompt/
I can indeed use Google, so I have already seen this thread. Problem is , many other threads dont mention anything about repartitioning etc. They just say : Write "Format x: /y " on cmd.
Why is that?
Are the rest of the steps needed if you are not installing Windows on the HDD?
