Windows Alternatives to NTFS?
Maidjeurtam asks: "I'm a multi-OS user. Although Linux is what I use the most these days (I run it on my primary P4 box and on my iBook), I also run Mac OS X and a Windows XP on other machines. Of course, those boxes are networked, but sometimes, I just prefer to plug one machine's hard disk into another. I often work with big DV files (> 4GiB) and it looks like I have no other choice than having a different filesystem on each of my boxes. Granted, Linux can read NTFS (Macs can too) and even write to NTFS partitions thanks to tools like Captive, but I don't like the idea of running Windows code on my Linux box. In fact, I don't want my data stored on a proprietary, closed filesystem. I've googled a bit and it seems there's no modern (free-as-in-speech) filesystem I can install on Windows. I'd love to have ReiserFS running on my XP box, for example. Am I condemned to stay with NTFS, or do you guys know of a Windows-compatible, open filesystem that I can use?"
Last I checked, you couldn't have files over 4 gb in size on a FAT partition.
What we did for file systems was standardize on ISO9660 throughout, though we are considering a move to UFS so we have support for larger files. Windows supports it, though you have to hack the registry to get write access enabled, and we ended up writing a custom "disk format" tool to actually get disks initialised because, needless to say, W2K doesn't actually allow you to format disks as ISO9660 by default.
Well recommended. There are some neat features of ISO9660, like the VAX/VMS style "versions" for instance. Unfortunately, bog standard ISO9660 has crappy 32.3 style filenames (and for maximum compatability we're encouraged to just do 8.3), so it's not a perfect solution (another reason we want to switch to UFS.)
Definitely recommended though. It's a little slow, but everything will read it.
Oke... but FAT32 sucks.. its slow.. its propetary and MS just recommends everyone to upgrade to NTFS..

Reiserfs under windows
I was actually thinking about this a few days ago. There's lots of work out there getting linux to run windows drivers, but I haven't seen much work on writing windows drivers for posix (*nix, whatever) stuff.
A while ago I downloaded the Windows DDK from Microsoft for something, but I didn't end up using it, uninstalled it and now I can't find the download. Unfortunately, it doesn't seem avail. for free from Microsoft's site anymore either (Microsoft WHDC DDK page). I have work to do, but this page seems like it might be of some help: OSROnline.com... maybe.
Anyways, the idea still stands, why aren't there win32 branches of open source file system drivers? Of course, I know squat about writing drivers, especially filesystem drivers, so there may be a damn good reason why not. But figured I'd throw it out anywho.
DONT PANIC
but I don't like the idea of running Windows code on my Linux box. In fact, I don't want my data stored on a proprietary, closed filesystem.
And this is why you will die very lonely.
Seriously though, what does it matter? You want files over 4 gig in Windows? You pretty much have to use NTFS. Deal with it.
Not All Who Wander Are Lost
Currently ext2 might be an alternative. There are two open source drivers, both quite buggy. There is also a commercial solution, which produces strange things. It worked for a while, then writing under (2k) makes double double sized - so it becomes full pretty quickly, unless you switch back and forth to do an fsck (which will repair, I mean correct the size without data damage).
It is a pity there is little interest in writing a good ext2 driver for windows - I think some of us would make good use of it, for good (and fast) data storage.
BTW, I don't use the commercial solution, its on my friends puter, and as I said, it worked fine for a while - and we don't know what caused it to register double sizes for data. It might be a windows thing, otherwise it worked perfectly (read-write). Name for commercial driver is Paragon ext2fs anywhere, or something like that (try google).
In fact, I don't want my data stored on a proprietary, closed filesystem.
Hmm, then maybe don't use Windows?! Seriously, why complain about the file system in particular when the entire OS is closed source. It's one thing to say "I only use OSS," but it's another to say "I don't mind closed source software, except for on this one part - there it's bad."
Windows is optimized for NTFS now, and NTFS is good. If you don't want propritary stuff, don't use Windows, period.
Explore ex2fs
I'd love to have ReiserFS running on my XP box, for example.
Reiser is not really appropriate here, because you want a filesystem for "large" files. Reiser's strength and efficiency is in large numbers of small files.

Sure, Windows 2000/XP support FAT32, but the maximum size for a file on a FAT32 filesystem is 4GB. The OP said that he was working with files bigger than that, which can't be stored on an FAT32 file system.
This has been a test. Had this been a real emergency, we would have fled in terror and you would not have been informed.
1) You don't know that he doesn't work for pixar, or that his work is not of value. Insulting his needs is not an answer to the question, it's the bitter bitching of a troll.
2) The poster, as you so unusefully point out, is aware of read access under Mac OS X and Linux, and is perfectly aware that he doesn't have an _access_ problem per se. He does, however, have an _access_ problem in that he can only write from one side. If he needs to write from the other he needs to move the files off box.
3) Apparently you're reading things the rest of us aren't. The poster is not complaining about things just because they're proprietary. What he is asking is if there is a way to do what he wants to do. You fail miserably to even address his issue in your brief rant.

- Am I condemned to stay with NTFS?
Yes, as long as you want stability and consistenty (as in error recovery, such as provided by metadata journaling), you are.Windows supports FAT32 and ISO9660 out of the box. FAT32 does not provide enough error recovery to be recommendable. People using ISO9660 as a hard-drive file system are crazy masochists -- enough said. There are seemingly abandoned ports of Ext2 and ReiserFS out there. None of them are in any sense stable for production use.
Why aren't there more file systems available on Windows? The first clue is that Windows is not an open-source platform; open-source hackers tend to live on open-source platforms. The people who work on kernel-level development under Windows are likely to be pursuing commercial software from the outset.
Furthermore, Windows kernel development is something of a black art; it is hard enough that you need to have some vested interest in the platform in order to stay; you would want to live and breathe Windows kernel APIs. (APIs, incidentally, that don't seem constructed for use by humans; for example, due to the limited size of the kernel addressing space, there are several different "kinds" of memory you must carefully allocate and manage yourself. Add to this the awkwardness involved in debugging this stuff, the poor kernel-level development tools offered by Microsoft, the limited documentation, the fact that much third-party information is non-gratis, and of course that the kernel sources themselves are closed, and you have one painful hobby.) In short, you would want to become a kernel specialist.
These painfully-accrued skills are worth their weight in gold, and used to leverage careers as highly-paid consultants or highly-paid trainers, or both. And some, of course, are driver writers for hardware companies.
There's a further reason: Linux file system drivers, in my experience, are designed to be, well, Linux file system drivers. Witness the amount of effort taken by IBM and SGI to port their proprietary journaling file systems to Linux -- and this was from one Unix-like kernel to another. Windows' internal file-system driver API is completely different from Linux'. Porting one file system not only requires a lot of knowledge about the different kernel APIs, but also about the file system itself, because most likely the file-system code is not cleanly separated from the kernel-specific code; you can't just sit down and write an adapter layer. (This is actually mostly speculation, but based on casual perusal of some existing driver code.)
There will be viable, open-source file systems on Windows the day somebody takes the time and effort do implement (and maintain) one. As for myself, I bought the book and started; I gave up not because it was technically challenging, but because it was no fun, and there were more interesting knowledge out there that I wanted to store in my brain.
Really, the issue is getting Windows to mount a drive which is not FAT/FAT32/ISO9660/NTFS. In order for an OS to mount a filesystem, there must be logic coded into the OS which will allow it to parse the file allocation tables and other information (journaling, etc.) and read and write files from/to the disk in that format. To the best of my knowledge, Microsoft has never supported any FS other than its own for HDD usage.
Fortunately for you, MS does have a filesystem-abstraction mechanism known as SMB, which several projects (most notably the SAMBA project) have implemented. These systems communicate with Windows via SMB, presenting information to the OS with parameters it understands. By proxy, then, the MS OS doesn't care a whit about what back end FS it's writing to - as far as it's concerned, it's just like any other MS OS via the network.
So probably the best solution is to have a network-mounted drive connected via a high-speed link (gigabit ethernet, etc.) on a linux box running SMB. If you do it right, you should hopefully have enough bandwidth to do your video and have it hosted wherever you like.
Good luck!

I've found that Linux (at least 2.4.something) will have problems using a fat32 filesystem over 128 GB in size. Windows will work with it fine, but Linux will work mostly but writing to one file will eventually cause another file to get truncated to zero bytes ... nasty.
I never really tracked down exactly what was going on, but it was easily reproducible on at least two different boxes just by creating a fat32 partition over 128 GB, using both mkdosfs and Partition Magic and mounting it under Linux and performing some operations on it.
This was actually asked sometime ago, sort of - the answer is OpenAFS
People who think they know everything are a great annoyance to those of us who do.
I don't think it is available now, but I think it would be a very useful thing to have this option available, even as a horrible hack.
On the side, I've been trying to round up information on what it takes to do this, but it sure has been a pain.
I'm not really sure why Microsoft it so tight-lipped about the IfsKit and the DDK, but my best guess is that they don't want the kind of support issues that would come with too many different kinds of file systems. I suppose they're thinking that if they make the barrier to entry sufficiently high, the only takers will be professional enough to provide a decent level of support so Microsoft doesn't have to.
For the vast majority of their customers, that is probably the right decision. But for the geeks (like me) who want to do crazy things with their computers, it sure is frustrating.
I actually work for Microsoft, so the good news is that I have access to the info. The bad news is that I probably can't open-source anything that I make with it, and that even if I could, it wouldn't be of any value (you'd have to have the IfsKit to build it...). But I'm looking into my options. My ideal would be to produce a usable interface for pluggable user-mode file systems. Performance wouldn't be great, but I think it would still be very useful. I'm pretty sure that I could release a free version (binary-only) of something would make at least a few geeks happy.
The plan is as follows: a driver provides a \\.\UMFS kernel namespace object that redirects IO requests to a user-mode service. The service has a set of registered plugins. A request for "\\.\UMFS\ReiserFS\Vol1\Hello.txt" would load the "ReiserFS" plugin and request "/Vol1/Hello.txt".
Once that is done, the rest is pretty easy. "Junctions" would allow you to make mount points into any desired branch of the UMFS tree, and the user-mode plugin interface would hopefully be reasonably simple. There could potentially be kernel-mode plugins as well, but that would be pretty far down the list of priorities.
The coolest part wouldn't be mounting ReiserFS, though. I think it would be much more interesting to implement filesystem access to other system resources -- WMI, Registry, Process/Thread table, etc.
Lot'sa other issues to worry about -- security, caching, etc. Not quite trivial. But it should be possible. Anyway, we'll see if I ever get time to implement it...

AFS appears to be a distributed file serving system, like Microsoft DFS.
- This was actually asked sometime ago, sort of - the answer is OpenAFS
It's not the answer. OpenAFS is not a local file system, which is what the original poster is asking about. OpenAFS is a distributed, networked file system implemented on top of an existing physical file system; it stores its files in whatever file system you're running, so on Windows it would be using NTFS or FAT.How about a Samba share? On either the 'nix or the XP box - or even on a 3rd file server of some sort? Or you could use SCP or SFTP.
Granted, I realize then you're copying stuff back and forth. But it seems to be the least buggy, most reliable solution.
Actually, the limitation I'm concerned about is FILE SIZE. Partition size is a different story. While Windows would cap FAT partitions at 2 GB for the first partition and 4 GB for the next 3 in Win95 and Win98 (not sure which editions), newer versions of FAT WILL CREATE 32GB PARTITIONS!
However, using Linux, I have created, and STILL USE a 62 GB FAT32 partition. I use it both in Linux and Windows with no problems. Windows can mount a much larger FAT filesystem than it will create.
This is not conjecture - this is my primary machine (running XP and Mandrake 9.1) and I'm typing from it now.
I do exactly the same thing, and eventually I decided the smartest way would be to use a networked filesystem. I have my DV box with mirrored (essential in my mind) 120GB drives running Debian and sharing via NFS over a 100Mb network. You could use any operating system on that box and it wouldn't matter.
I can rip DV footage to it with no lost frames and no problems. I also do a lot of audio recording, and can record at least 12 simultaneous tracks to it.
I can access it from any computer, it's never down, I don't have to restart to get into my files, everything just works!
"a distributed file serving system, like Microsoft DFS." ..Not!
"Microsoft DFS" is nothing but a redirector that creates the illusion of a single filesystem tree from a set of regular old SMB servers.
Napster-to-go says "Fill and refill your compatible MP3 player", which is a lie. It's not MP3. It's WMA with DRM.
UDF is the Universal Disk Format. Although generally used for DVD+-RW disks, it can be used for harddisks too. All the modern operating systems support it, including Microsoft Windows (apparently since win95b).

You might have just hit it.
The issue with wanting everthing OSS on windows is that it makes migration easier. Almost every company has 1 or 2 apps that have to be on windows...so the key is replacing one-at-a-time...mozilla here, openoffice.org there... It's a page right out of the MS playbook...cooperate with everything and quietly switch user bases. But with OSS you won't ever be FORCED to switch and pay more money!!!
That search shows nothing relevant. Does this mean it's now a 'valid' question, or that you are a wiener?
This is a joke. I am joking. Joke joke joke.
there's a commercial, and I believe, several free versions of "ext2fs for windows" you might wish to google for that. You would be able to share your ext2fs file system with your linux install. However, they aren't "install" options. Only fat32 fat16 and ntfs qualify as "install" options on windows operating systems, and I doubt there is a bare-metal recovery kit in existance that would allow you to "backup ntfs install", reformat to ext2fs, "restore from bare metal onto ext2fs" and voila, without blue screens galore.
But write support is no longer marked experimental in the 2.6 kernel.
For good reason I'd say, I've been using NTFS write support for the past several revisions without a single hiccup.
First I was cautious and ginger in my handling of NTFS writes, and then more bold. Now I don't consider corruption anymore than I would with windows. I guess that comes from hundreds if not thousands of writes without a single issue *shrugs*.
In any case, if the kernel maintainers think it's safe to take off the experimental tag, and I've used it without any problems. Maybe it'll go well for you too.
NTFS write used to be horrid, and required external cleanup utils just to use. That's long long gone, if you've been afraid to touch it because of being burned in the past, seriously, it's time to try again.
How about installing a NFS client on your windows workstation and make yourself a NFS file server with a linux 2.6.x kernel?
Gigabit ethernet card are cheap these days and you can get yourself a nice SATA raid that will be able to handle your huge DV files.
Seb
Granted they won't allow you to just switch harddisks, but a fileserver is not that expensive (just a cheap pc, with a somewhat big powersupply, a few promise cards for extra ide and 8 or so 200 GB disks should be less than $2000)
You can stream to that over a standard network with peak rates that approach line speed (100 mbit) and I get sustained 90 mbit rates every day (just don't overload those disks, as they are ide disks, not meant for constant use)
Fileservers are good. See one here (good, not great) or just build yourself a cheap box and put massive storage in it, and attach it to your 100Mb network.
I want a good common filesystem, and not just for Windows. I want a filesystem that Linux, FreeBSD, Solaris, OSX and Windows can read/write. The "good" criteria eliminates FAT32. UFS is free, open, tried and true. So why is it only available readonly in Linux?
Don't blame me, I didn't vote for either of them!
I can't help but notice how many people have mentioned that NTFS write support is not marked experimental anymore, yet nobody has said if they can _really_ use NTFS from Linux. Has anyone been able to create files or directories? How about changing the file size, or deleting files? If you have, we need to talk... I would like to know how to get that level of functionality for myself and others.
Yup, been using it for about 2yrs now without a hitch.
The part which is no longer marked experimental isn't full write support however. A couple people corrected me on that and I double checked and their correct.
However you can still turn on NTFS write support and NTFS write support has worked great for me since I'd say about midway through the 2.4 kernel series. No special trick, just turn it on and use it.
A few disclaimers, i'm not even sure I've used it since using a 2.6 kernel, I'm not sure I haven't either to be honest but I know I never had a problem from the default rh9+freshrpms updates kernel on up. Aside from NT passhack floppies I'm not sure I've used anything but a redhat kernel (I don't know of any redhat specific patches for it though).
Second, I KNOW I've never tried to chown/chmod or create symlinks. Creating files and directories I've done without problems. Resizing files??? Not sure what you mean here, if you mean opening a text file and adding more to it yes.
Deleting files is not an issue. Basically I've used it as a transfer partition on dual boot systems (both ways), for data recovery (in read scenerios and to transfer from the bad drive to the good ntfs partition so write as well).
Not sure I've even tried to read an NTFS compressed or encrypted partition as well.
Really I've had no problems. Everything I've tried has worked but my needs have never included actually mounting the drive and using it as a true linux mount. Just a place to copy that latest windows only app I want to take a peek at or my latest svcd images if low on space on my home system. At work I use NTFS write all the time to recover data.
My general rule of thumb is to treat an NTFS partition like a fat32 partition. And of course you probably wouldn't want to touch windows system files on the drive since you'll likely lose permissions on them but if that's corruption I'm the easter bunny, the administrator can own the files.
Why can't someone write a virus that prevents Windows from creating Recycle Bin directories on any partition it gets near?
I see even classic Slashdot is now pretty much unusable on dial up anymore.
noatime and no 8.3 file name generation is off in reg for NTFS so it already has a benefit there. Originally the disk was a replacement disk (7200RPM laptop drive vs 5400). I was looking at perf figures before I installed it as a system disk with the FAT32 and NTFS fs's in the sam loc during after reformatting the same partition.
.5X by the end of the disk.
.4 as fast as FAT32, USB2.0 was topping out at ~.6 of the speed on FAT32, but about .5 the speed when using NTFS and that's where NTFS was slowest.
I'm aware of the outer sectors reading slowly -- I see it painfully obviously where on a clean disk a "dd" (I have linux on the sys too, dual boot) will start at rate X and almost be down to
I was running tests over USB2.0, Firewire and as an "extra" internal HD. Firewire and internal IDE HD w/NTFS were about
Now, I get some of the bene's I need for username security by using a small NTFS partition (basically to install their unix extensions on to play w/), while getting perf bene's for files that don't need separate username management.
Most of my files don't need username management because it is a _laptop_. You still need a username/pw to log into the computer. The fs isn't exported (2-way 3rd party fw, default block).
For a _personal_ computer, I haven't found the overhead of NTFS (and problems easily reading/writing it from Linux). Like the original poster, I'd like rely on something other than windows code to have r/w access to my files. Theoretically, doesn't matter if you can use the virtualized Windows driver for r/w access -- you still need to have bought an authorized copy of Windows to run the driver on your machine. No?

Several years ago I used a slackware 7 box with KDE (and konqueror and K-manage) to administrate and provide DHCP and mail services for an NT network, another *x alpha box was the file and app server (radius, webtrends, etc) All of the NT boxes had their native partitions and the OS and native apps mounted on NTFS. The whole rest of the network was EXT2FS and it was flawless under samba 2. I haven't built a trick *x box in a few years but if they have a journaled file system now I'm ready to build a new one :)
