ShutDown kernel panic with hard disks that are sleeping

Hi, sometimes when i try to shutdown the computer, it gives a kernel panic after it quits all left open apps. Then i realize it does this only after about 10 or 15 minutes of use, which means probably when my other hdds are put to sleep.

from Energy Saver settings, i've disabled hard disk seleeping but i have an external usb drive which i use for time machine backups and i can't prevent it to put itself to sleep after a while.

Is there any solution for this?

I had the same problem with an External firewire drive, that also goes to sleep on its own and it cause the same problem, I have no solution just reporting.
I can only guess its because SL doesnt acknowledge the drive is already powered off and tries to turn it off anyway.
