<br><font size=2 face="sans-serif">Yes you are right that when you did
the "echo..." command the way you did, you need to reboot. This
is 'cos you added a line to the end of the file /etc/rc.d/rc.local (that
is what >> does). The commands in this file are executed during
system boot. </font>
<br>
<br><font size=2 face="sans-serif">Now if you just type the command</font>
<br><tt><font size=2> /sbin/hdparm
-d1 /dev/hda</font></tt>
<br><font size=2 face="sans-serif"> Then it will execute
right away</font>
<br>
