That gives me most of what I want. Are the atactl commands perpertual, or is
this something I must do after each reboot? In this case, is it the drive
firmware that monitor the activity, or the OS?
Also, I have three drives. wd0 and wd1 are in a RAID 1 configuration with
RAIDframe. I assume that I must issue the command to both individually, and
not to the raid0 device? Will that screw up my RAID setup?
Thanks for all the help.
