file system compatibility...

[Angelo Moreschini]

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 ??*

Thank you

Regards

Angelo

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.

4GB -1 byte.  And, if you need to worry about permissions, ownership and 
so on, there's freeware driver, 
http://dl.paragon-software.com/free/Paragon_ExtFS_for_Windows_2.198.exe, 
that lets Windows computers read/write ext4 file systems.  (No, I 
haven't tested it yet.  If you do, please let me know how it works.)

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.

He already said he's using NTFS but he's having problems with it. The
problems may not be related to the filesystem of course.

I apologize for not answer the question you're asking.

However, a friend of my had a similar request not too long ago.  I told him not to bother with his idea and to simply go out and get a NAS.  He was a bit tight on money but he still went out and got a low end Synology NAS with 2x3TB drives.  Final cost was less than US$400.

The data is available to all of his devices.  Including his mobile devices.  And, of course, he has RAID to minimize loss of data.

With the NAS devices you can get other set of problems. I have for 
example been rescuing data from NAS which had sparc processor and it had 
formatted ext3 in a way that you couldn't read it in Intel processor 
machines without doing extra things and using drivers in alpha state 
(and which development had stopped and you needed to compile yourself)

So if going to nas route should check that you can actually get 
something out of the drives in case of box going bad. Or actually take 
backups instead of always planning to do them.
If you don't mind others (Like your more or less friendly spy agencies) 
to read the code in git repository one way to share the stuff with 
multiple machine is actually keeping the repo in Dropbox or something 
similar which actually copies the data to multiple places.

I never worry about losing data should my NAS box hardware go bad.  I live in Taipei and all I would have to do is take it to a shop in the Guang Hua market that sells that brand of NAS and they'll recover the data for free.  One of the many perks of living in a place where "service" is not a dirty word.  :-)

But, yes, every solution comes with its own set of issues.  You just have to weigh them and their probabilities.  For some folks cloud services aren't ideal due to network issues.
