XBOX HDD read / write on a mac

I took the 500GB (incl games) from my JTAG XBOX 360 & connected it to a mac.

But I don’t see the HDD in finder. How do I read/write to it?

I don’t to reformat it if possible as I don’t want to lose the games already on there. Thanks

What did you use to connect it?
What program are you using to to “find” your drive?
