how to prevent my external drive from waking up when my mac wakes up?

[Afro1989]

i have a 2 TB external hard drive that i use very sparingly throughout the week to listen to iTunes or save documents.

i would like to have this drive mounted 24/7, but don't need it to constantly spin up every time i wake my mac up from sleep (which is about 4-5 times a day).

i want the drive to last and don't want to put unnecessary wear and tear on it.

thanks.

You could try ejecting it with Disk Utility. Should be able to remount it with Disk Utility as well when you need it.

yeah, i actually tried this and after i eject it from disc utility there is no way for me to remount it without physically turning it off and then on again.

What make model hard drive is it?

I am doing this ok with LaCie d2 Quadra drives. When I eject them via disk utility, they spin down but remain powered. It sounds like your drive is full on going off.

well, i use this applescript


set vol to "HD2"

tell application "Finder"
if (exists disk vol) then
do shell script "diskutil eject /Volumes/" & vol
else
set device to do shell script "diskutil list |grep " & vol & " |awk '{print $6}'"
do shell script "diskutil mount /dev/" & device
end if
end tell

It toggles the state of the hard disk.
I compiled to an 'app' and then put it in the user scripts folder. Now it sits up in the menu bar and i can dismount or mount the second aux hd whenever i choose.

This used to work great with snow leopard. However, in Lion, whenever i open my macbook pro (and it wakes up from sleep) the aux hard disk is spun up by lion. What a pain in the A$$.

How can I stop this lion misbehavior?
