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.
