XFS w/ Mac OS X
 

As stated in the subject, I need help reading/writing to my external XFS HD using my MacBook Pro. The HD is attached to my laptop using a USB 2.0 enclosure.

If anybody out there knows of any projects or any tools provided by Apple that will allow me to do this, it'll be much appreciated.

I can also live with reformatting the HD to ext3 (which has support for MAC OS X) as long as I don't lose my data (burning the data to DVD's or transferring it to another HD is not an option since the HD in question is a 400GB disk which is mostly full).
