Only if the Mac wrote one.

History of the disk as I remember it:

On NetBSD:
Use fdisk to create the MBR with 2 partitions: initially FAT32 and NetBSD.
use disklabel to create matching disklabel.  Initially put a NetBSD ffs in the 
NetBSD partition.

Let Windows XP format the FAT32 partition.

Some time latter decide I want to share the Unix partition between NetBSD and 
MacOS and it looks like I can do this if its a MacOS X UFS so:

Use "Disk Utility" on the Mac to erase and reformat the second "Volume" on the 
Disk as "UFS".  (doing this caused disklabel on NetBSD to report partition f 
as Apple_UFS rather than 4.2BSD)

Which gets me to where I am currently: the Mac can see the Volume the NetBSD 
box fails to mount.
