Message-ID: Date: 2 Aug 89 00:49:12 GMT Sender: news@tut.cis.ohio-state.edu Organization: Info-1100 Mailing List Lines: 8 The Quantum Q540 (the 40 Mb drive in most doves) has a spring-loaded mechanism that moves the heads to the safe "landing zone" when the disk is powered off. When the disk is powered on, the airflow generated by a vane on the spinning disk is what pushes the spring away, allowing the heads to move to other parts of the disk. Sounds failsafe to me. --Christphero -------
