I want to know if there is a way to download specific block numbers without download the whole blockchain.

Edit: I know that I can use bitcoin client with getblock "hash" function, but this require that the block with that "hash" to be in the hard drive, which I don't. So I'm looking for a similar function of getblock "hash" which doesn't require block to be in the hard drive, but instead it download it from some server or other peers.
