What is the approved method of turning off the ide/ata disk spindown
via atactl?  I've had the following in my /etc/apm/line file for a
while, but it appears my disk still spins down every ~10 minutes or so
only to spin up again within a few seconds.

	atactl wd0 setidle 0

Should I be setting the idle time to some very large number instead?

This is what the kernel says about the disk on boot.  The machine is a
sony 505tx with the bios apm-related disk stuff turned off in the bios
