I been tinkering around. Setting the spindown to 30 mins via "hdparm -S 241/dev/sda". However, i am finding hard to track down the things which are writing to the drives. Sure I can use lsof or fuser to find them, but that's just a hassle. Oh, I also tried to add noatime to my fstab.<div>

</div>I believe hdparm is still the tool to use since the actual spinning<br>
down can be done by the drive itself. The big problem with this<br>
however is getting MythTV and the rest of your system (like gnome) to<br>
stop trying to access drives when it does not need to.<br>
