So I just received a new mac after having many problems with my old MacBook. When I started up, the hard disk was only to be found in the finder, whereas I like it on my desktop. When I dragged and released onto my desktop, it went poof! And now it is never to be seen again. I've done a search through finder and I cannot find it anywhere. I can get by without it by searching through my finder - but I really like my hard disk button-thingy (especially on my desktop!). Please help!
