How have you managed to do this?  Is this a Maxtor feature? or some driver(s) 
for Linux?  I've been wanting to do exactly this for some time but have not 
been able to...  Any pointers or info would be appreciated.

All depends.  On the RAID5 I have running at work & home I have a hot-spare & 
I have a hdparm -y /dev/hdg in rc.local which puts it to sleep after boot-up 
as its useless having it spin if its not needed.  NOTE: I have never been 
able to get hdparm -Y /dev/hdg working on any drive even those that are 
suppost to support it.  Again any pointers or info would be appreciated.
