Slow Shutdown with Leopard - Possible Solution 2

Hi, I thought I would share with you all something that Bob posted in the comments that has also resulted in an improvement in the shutdown times of our macs, this is something that he mentioned finding over at macosxhints.com but I thought I would share it here as well as its useful information.

For this solution, you will need to use the terminal but its quite easy, open the terminal and enter the following commands pressing enter after each one (NB: After the first command you will be prompted for you password, enter it and after that you should not be prompted again).

sudo pmset -a hibernatemode 0

sudo nvram "use-nvramrc?"=false

sudo rm /private/var/vm/sleepimage

After entering these commands my MBP shuts down in seconds, mainly because its not creating a 4GB sleepimage or trying to page the contents of RAM there. Im trying to understand now though what the correlation between the windows drive and sleep is, as unmounting windows also has the same effect...
