I have an external case with USB 2.0 and Firewire connections on it.
I installed a 200GB ATA drive in it. My plan is to use this disk as a
method of moving my personal files wherever I go. Work, Home, buddies
house, etc.

I assume that I will be making smaller partitions such as 3 62GB
partitions of 4 46.5 (assuming 186GB of usable partition space).

Anyone have any insight or experience with this? I searched many
newsgroups but couldn't find any articles attmpted to use a portable
disk across the OSs I mentioned.

Are fat32 partitions the best way to go?
Will all partitions be recognized in each OS?

Any help is greatly appreciated.

Thanks,
-Erik
