Hi ,

I need to use an USB Hard Disk as repository; that is a "subversion
repository" that is used in a local network.

This means (for me) that the data wrote inside the HD can be used, in
case of emergency, bot on OS Linux both on OS Windows ....

Actually in this Hard Disk (that have ntfs file system) are stored data
writed from OS Windows XP; and I am not able to read (easily) this
data in OS Fedora.

Actually I can read only some directories there... :
- $RECYCLED BIN
- RECYCLER
- System Volume Information

As well it is not the best..., it is not very important for me to lose
the data actually wrote in this Hard Disk,
But  I would be sure that IN THE FUTURE SHALL BE COMPOTIBILITY of
usage between Fedora and Windows..
i.e. *_I could indifferently use the Hard Disk with Fedora and with
Windos.._*

*_I think this if possible, using some File System that allow this
possibility, by the creation of a special partition on the HD._*

What I think is rigth ?
In case the answer is yes.. *_with wich File System I have to format
this partition ??_*

Use NTFS. Windows and Fedora will read/write NTFS. It's a journaled file
system so it's a bit safer to use than FAT32 (in particular the journal
obviates most repairs in case of a crash, so it's usually not necessary
to fsck the disk). And also FAT32 has a 2GB file size limitation which
can be a problem.

Keep in mind, however, that there MAY be permissions/ownership issues as
NTFS permissions and ownership do not translate directly to Linux. If
the filesystem is mounted by root and root does the read/write to it,
it'll probably be OK, but just be careful.

There is no 100% compatible mechanism between Linux and Windows. You can
use things like NFS or Samba to sort of mitigate the major hurdles, but
there is nothing that's going to map 1 to 1. FAT32 has the fewest attributes so the compatibility is better, but it's still not 1 to 1.
Windows and Linux are just completely different beasties. Linux does a
better job "accommodating" Windows filesystems, but the reverse sure
isn't true.
