I uploaded a video to YouTube of my old iMac HD. It's making odd buzzing sounds. I've tried to connect it to my MacBook Pro via SATA/USB, but it doesn't show up on the desktop. Has anyone had a similar experience with their HD? Were you able to get any data off of it? Unfortunately, all the data on it wasn't backed up so I'm wondering if all my photos, music and what not is gone forever. Many thanks.
