I experienced this problem on three different machines (two laptops and one desktop). It's like the Hard Disk heads are not parked before the power is cut off. Same problem on OpenBSD but not on NetBSD, where some parking is made. I fear this problem could potentially shorten the life of my HDDs. Thank you. >How-To-Repeat: Turn off the system via 'shutdown -hp now' or 'halt -p' >Fix: None as of now. >Release-Note: >Audit-Trail: >Unformatted:
