File system for external hard drive?

Potentially stupid question.

Buying a HD and external enclosure. I use Ubuntu/Win2k on one computer and WinXP on the other.

I should be formatting the HD as a FAT32 drive if I want it to work with everything, right?

i thought the driver is for ext3, but it's for ext2. it doesn't really matter because its all backwards compatible. ext3 is just a ext2 with journaling, so you don't have do defragment ext2 either.

yes, its possible to use two partitions and it'll show up as two drives. well, just windows will tell you that there are two drives, but it'll be usable on all major platforms.
and yes, ext2/3 is *very* reliable and FAST. the driver doesn't support journaling (from ext3) though, but it's not a too big disadvantage.
