partion and fs advice...

[Jeff D. Hamann]

I've just recieved a new laptop and need (yes actually need) to run both 
winxp and freebsd. I've got software on both systems and need to be able to 
access data on one of the other. I have a 100GB hard drive with XP installed 
onthe first 20 GB and my question is this:

What file systems can I choose from to be able to create a partition I can 
read/write from both FreeBSD and WinXP.

It's been too long since I've tried to have my cake and eat it too and I'm 
not sure if there are drivers out there for reading extfs from win32 and 
vice-versa. I need to have a common (hopefully *NOT* a DOS partition) place 
for data (databases, scripts, etc.) and would like to have two partions for 
the OSes so something like,

20GB - windows xp
20GB - freebsd
60GB - data/scripts/etc (would be the "D" drive for winxp and the /usr/home 
for freebsd)

The laptop has 2gb ram (not sure if that's important) and a real niec lcd 
screen and more ports than i've ever seen on a machine (sager 3880)

I'll need lots of space for compiling ports (GRASS, postgis, R, etc.) and 
really, REALLY, *REALLY* don't want to use cygwin anymore.

Any advice would be greatly appreciated.

Thanks,
Jeff.
