samples taken while the disk is spinning. If no 'disk idle' samples are available, use the ones we have anyway (yeah, maybe we could interpolate too). Also tuned the deltas detection too, and fixed some comments. This seems to work quite a bit better for me. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@1682 a1c6a512-1295-4272-9138-f99709370657
