Has anyone out there tried locking/unlocking the local rigid disk (42/80 MB, ST412/ST506) on a 1186 ? Or is it one of those device that will do auto-lock/auto-unlock when one powers down/up the system ? I looked up the 1186 User's Guide and it didn't mention anything about locking/unlocking rigid disks. Any pointers will be much appreciated. -- Eric Ho Cognitive Science Lab., Princeton University voice = 609-987-2819 (x2987) email = eho@confidence.princeton.edu eho@bogey.princeton.edu regards. -eric-

Powering on the 1186 will cause the disk heads unlocked to become unlocked. You need to lock the head with software. To do this, 1) use the latest Offline Diagnostics (Version 1.5) 2) login as a normal user 3) choose the option Formatter, Scavenger & Bad Page Utility (answer yes to is the disk formatted) 4) choose Head Retraction and follow the directions *becky*

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 -------

If you have the Lyric or later version of Systemtools you can do the following: 1. Do an F5 boot (Diagnostic Rigid Disk Boot) 2. Immediatelly hit the STOP key and hold it until the screen reverets to black and the flashing cursor code stops at 'A499' 3 Hit the "F" key subsequently followed by the "D" key and wait until the cursor code changes to '1B99' 4. Hit the "S" key subsequently followed by the "5" key and a Carriage Return. The cursor code will remain still for a little while and will eventually become "1B99". Carl
