How show only specific devices on Desktop?

[reubs]

I like to keep my desktop rather tidy, but I like to keep the connected devices there so that I know they are connected. However, I have a protected DMG on one of the connected drives, and having both the connected drive AND the protected DMG is not what I want.

What I'd like to do is simply have the DMG show up on the desktop and NOT the drive the DMG is found on. Is there any way to specify which specific devices I'd like to have show up, or am I stuck with only the option Finder gives me?

These are the only options that Finder provides:
*Hard disks
*External Drives
*CD's, DVD's, and iPod's
*Connected Servers

It doesn't look like you'll be able to make it so Finder won't show the Device you don't want to see. However, you can try going through the back door...

If you run

defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder

in terminal, it will show all hidden files. After you do that, put a period in front of the drive name. OS X will ask you if you want to do this for sure, click yes. Then run the same command as above but change TRUE to FALSE.

You won't be able to see that drive until you run the above command again. Not a very efficient way of doing this, but it should work.
