reading linux from MacOs

[raphaello <raphaello-debianuser@altern.org>]

Hi all,
From my MacOS 9.0.4 working, I would like to read the linux files of 
my Debian woody.

But MacOS doesn't see the other disks, even the Apple System 
Information see only my 4 Go HD MacOS partition, when all the HD is 6 
Go big.

I need some magic ?
