Hello. On one of my workstaions (AMD64, FBSD 5.4-STABLE) I utilize two SATA drives, one is a 200GB Maxtor (2B200MO, SATA I), the other a Samsung 200GB (SP2004C, SATA II). Using atacontrol cap <channel> <device> shows me on both devices power management yes yes advanced power management yes no automatic acoustic management yes yes Is there a way to disable automatic acoustic management and power management forever? Mainboard is a ASUS A8N-SLI Deluxe, BIOS 1010 (most recent), Operation System FreeBSD 5.4-STABLE as most recent cvsupdated (I think this doesn't matter, but ...). I did not find any knob in the BIOS disbaling acoustic and power management for the attached harddrives, so I'm a little bit confused. Especially the Samsung drives seems to need about 1 or 2 seconds 'starting' when accessed after a while of inactivity, means when showing a directory content, it takes a while before the informations show up. Thanks, Oliver
