None of this matters - as you know, there is no way to do what the OP
asked and indeed, no definition of what he means. Is a floppy a "hard
drive"? Is a memory stick a hard drive? Is a network block devcie a hard
drive? Enrique made a reasonable guess at the OP's level of understanding
and gave him an answer that would satisfy him. I agree with you however
that that is an immoral thing to do to a person.

Which doesn't attack the problem - it's his head that doesn't know what a
hard drive is, not us.
