Can't keep individual drive powered down while array is stopped

I've found myself in the situation of having to remove specific drives in my array that's in a 5in3 hotswap bay.  I want to spin down (and ideally power off) the drive before removing, but the bay does NOT have individual power buttons for each drive.  I stop the array then power down the device using "hdparm -Y /dev/sdX" which works fine, but it automatically powers back on and spins up 5 seconds later.  Is there a way to stop it from powering back up (or a better approach to this situation), so I can hot swap safely?

This should work:


echo 1 > /sys/block/sdX/device/delete


Oops I forgot to mention I tried this as well.  Same thing - it works but then powers right back up.
