I tried doing it in Windows, and in Leopard it doesn't let me. Is there a program that can do it, so instead of it saying Untitled, it says Windows HDD Pic below. Edit: FOUND A SOLUTION, EVEN WHEN YOU HAVE NTFS 1. Go into Windows 2. Right click on my computer>properties 3. Find device manager (forgot which tab it's under) 4. Go to disk drives 5. Right click on the HDD and hit properties? (Something like that) 6. Go threw each tab until you see something called "Populate" at the bottom, hit that and let the drives appear. 7. Rename the partition, restart and go to Leopard and it will work How do I know this works? Well, I went into Windows, and restarted and went back into Leopard. My partition wasn't there :S So I went back INTO Windows, did the populate thing and booted back into Leopard and it's fine. You shouldn't have to rename it again, but you have to hit populate. So if you formated to NTFS (which is the smart thing to do cause Fat32 has a limit of 4GB or something), every time you go into Windows and back into Leopard, you need to populate in the properties.
