When the hard drive is off the heads should be on the orange parking ramp.

When the hard drive is turned on the disk start spinning and the head move off the parking ramp and float on the disk surface. The heads float on a pocket of air much like a hockey puck on a hockey table. It should never touch the disk surface.
When the hard drive is turned off the heads are moved to the parking ramp and the disk stops spinning.

If the drive is unplugged from the computer quickly and if the heads can’t make it to the parking ramp fast enough the heads will come to a screatching hault on the disk surface. Sometimes the heads crash when this happends, sometimes they don’t. The heads normally stick to the disk surface preventing the disk from spinning. This will cause a beeping noise. If the heads are not crashed we can normally free it up and recover your data for under $400. If your heads are crashed it will be a normal head replacement recovery
