you should try adding ' /sbin/hdparm -c1d1k1 /dev/hdb '  to your 
/etc/rc.d/rc.local script.. worked here for me.  perhaps it was not fully 
qualified for the command on your box.

BTW.. I had seen hdparm before but never messed with it until today when I 
saw your post.. thanks.. since I started with it I have now just less than 
tripled my hd r/w speed.  Excellent
