Sharing Data between Windows 7 and OSX 10.5 (BOOTCAMP)

Hi -

For about a year I've been running windows xp and osx 10.5 with bootcamp seamlessly sharing data between the two by creating a third partition as a shared drive. i've been using this guide, that describes how and which system files to modify

is this possible in windows 7? would it be the same steps, or different, or what? Basically, I would just need to modify the boot.ini file in windows 7 to recognize the 3rd partition but still be the primary windows partition to boot to. does anyone know if it is the same process?


edit: just found out about MacFUSE and NTFS 3g... problem solved?

I'm using the same exact procedure for a 3 partition setup with XP. It turns out that in vista and windows 7, there is no boot.ini file. Luckily both vista and 7 are smart enough that you don't need to edit anything, but you'll have to make the 3rd partition before installing windows rather than after. Here is what someone posted on that webpage in the comments. See #3 especially below.

Yeah, I did the same thing... ie:

1. format entire HDD as HFS & install Leopard
2. Use boot camp assistant to create bootcamp partition
3. use Disk utility to split the HFS partition and create a FAT32 partition
4. Install vista on boot camp partition
5. keep data on Fat32 partition

or, if your comp has an sd card reader, just put an sd card in there and use that as a transfer drive

Maybe a simpler method

I didn't have a problem sharing data between OS's. I just created a folder in Windows 7 c-drive (root) called "shared_media". It is visible in the bootcamp icon in the Mac and you can read/write to it.
