When my Apple 80 was fixed (by replacing the PROM), it also started this, since the PROM tells the drive mechanism to do some seeks when idle and also to increase start-up torque. At times, it was VERY loud and it wasn't like this before the PROM upgrade. I had the dealer replace the drive (this new one also has the new PROM), and now no problem. Tech. support theorized that the drive mechanism couldn't handle the additional strain (mainly of the increased start-up torque) and was crapping out. Maybe,.... just check your drive.
