Problem to save file on the hard disk! What I have to set to do it ?

[Matteo]

Ok hda3 is "ext3", but I have a window "FAT" on hda1 and hda2, so I could save
my file in this partitions? 
But I see from the error message that RTEMS can't mount all my partition hda1,2
(FAT) for windows and hda3,4 (ext3) for linux.
Can you help to save a file in one of this partitions ?
Is there any way to save on a "ext3" partitions ?(Because I have to test RTEMS
on some linux systems and I'm afraid they are all "ext3"!)
