The noise that is being described sounds just like a disk-head being parked (these are the same laptop drives that say "drive may rattle, this is normal" on the label), and I'd be more worried if it /wasn't/ hasn't the disk-heads. It's quite satisfying to know that the heads have been 'clicked' into place.
