Yes, this is completely normal. Snow Leopard is designed to take up less space.

I did this, and everything seems to be running fine now, but I mysteriously have around 20 gigs of harddrive space that I didn’t have before. Is this normal, or did something definitely go wrong? My files all seem to be there and my applications are running fine so far, I just have no idea where all of that free space could have come from.

this works great. i either downloaded or copied a dvd of snow leopard. i forget if it was retail or hacked or not, but its bigger than 4GB so it won’t fit on a DVD.
at first i was trying to install from a hazard image i burned to a dvd but i got too many panic errors and i’m installing on mac not pc.
i reset the nvram and the dvd ejected and then i restarted and held down Option and it booted off my external usb hard drive

1334,

Do you still need to partition the external hard drive?

Just a heads up for all you “old school” mac users like me, this guide works for PowerPC with 2 little changes. Most PPC will ONLY boot from a FireWire drive, and select Apple Partition Map instead of guid. Just a quick tip!

I need help.
I have scanned the image but it still asks me to scan again after asking me type the password to confirm. So I can not restore the image to USB.
Thank you.

A solution without an external USB drive to partition. Requires you doing a fresh install at some point of Tiger or Leopard before updating to Snow Leopard. I happened to have just done a fresh install a few weeks ago.
It requires partitioning a small portion of the Mac hardrive so you have a 10 GB partition setup as explained in the above tutorial. Then after you have created a DMG of Snow Leopard and have it saved to anywhere(desktop) is what I do. In disk utility on restore just set the dmg as source and drag your new 10gb partition as destination.

My MacBook optical is broke but this has always worked for me.

Hi, i followed all the step but when i got to the step when i have to reboot and press the alt/option button and select the startup disk, i selected the snow leopard drive but it then went back to my original one

this happened to me too with a restart and a blank screen. anyone figure it out? i have my dmg file on a USB junk drive if that helps solve the problem.

i was able to start the install from the USB drive instead of restarting and holding the apple button (when i did it after the restart i was never prompted with a list that included the USB drive, only the mac HD)
