fat32 works with both, but you are limited to 2gb max file size (i think.. oir maybe it was 4).. i now use an ext2 partition and ext2fsd for windows (on sourceforge),
FAT32 supports filesizes up to 4GB and no larger than that. This is good enough for most thing except those who do videoediting, and of course DVD-ISO's (typical 4.5 to 9.8 GB in size).
There are drivers to windows making it possible to use ext3fs and ext3fs from windows, with read/write (but you probably have to be logged in as Administrator to do so - or have Administrator rights - superuser isn't enough).
You can also use captive drivers for linux, making it possible to read and write to NTFS partitions, but ext3fs is a better filesystem, so stick to that if possible for you.
