I recently bought a 160GB drive to put into my external enclosure to use as 
a portable drive. My goal is to develop a portable hard drive that can be 
used on my Windows and NetBSD machines.

The problem is that Windows XP will not format a drive larger than 32GB as 
FAT32. I could format it as NTFS, but then other computers writing to the 
disk run a small, but not insignificant, chance of trashing the system 
(that is to say I have seen it happen). I could format it as FAT32 in 
NetBSD, but then the cluster size is rather large and inefficient (32k I 
believe). So something better than FAT32 should be used.

So my bright idea is to format it using the Macintosh file system and use 
the MacDrive driver that comes with XPlay (used for accesing the iPod disk 
in windows) to access it. My guess is that this filesystem will be more 
efficient. Is this a correct assumption?

Also, has anybody done any other tricks to get a large, efficient file 
system onto a disk that is readable in WindowsXP? Perhaps someone has 
written a Windows driver for ext2,3 or ffs?
