I have a system with two IDE drives, where the second drive spins down after 10 or so minutes of computer idle-time. It is very annoying because the system will lock up while it waits for the second drive to spin back up, which can take a couple of seconds. (There is also the issue of additional wear and tear on the drive as it spins up and down.) These are the drives, as shown by dmesg: wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <WDC AC21600H> wd0: 1549MB (3173184 sectors), 3148 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (wd1): <WDC AC2540H> wd1: 515MB (1056384 sectors), 1048 cyls, 16 heads, 63 S/T, 512 B/S I also see these messages in /var/log/messages: Oct 3 21:17:09 guava /kernel: wd1: interrupt timeout: Oct 3 21:17:09 guava /kernel: wd1: status 50<rdy,seekdone> error 1<no_dam> Which I assume is the kernel complaining that it couldn't read from the drive, because it was in the process of spinning back up. I am running FreeBSD 2.2.7. I have power management at the BIOS level turned off, and the first drive does not ever spin down. I also have APM support turned off in /etc/rc.conf. Is there a way that I can force the drive to not spin down? I suppose I am looking for a tool like Linux's hdparm? A search of the mailing list archives didn't yield any solutions.
