Question ext3 filesystem read/write in xp


I've got a Linksys nslu2 NAS device and am using the ext3 filesystem on it's attached drives. It's a great little device - I mount it from Linux and XP.

Copying over the network is a bit slow (tx rate about 6Gb per hour) so I'd like to plug it directly to XP machines via usb for larger data transfer rates.

So ...

I don't want to format the NSLU2 drives in FAT32 or NTFS (still not convinced that NTFS will work right anyway) - so can I read & write ext3 from XP??

I've seen threads from the past like this one >> http://www.linuxquestions.org/questions/showthread.php?t=332656
in which the matter is thoroughly debated, but still cannot seem to get to a definitive answer.

I've tried 3 different ext2/3 utils with fairly mixed results (ext2fs being the only writable offering)

Magic wand anyone ?

Did you try
http://www.fs-driver.org/index.html ? I've used it for quite some time and it performed well.

I've tried Ext2IFS_1_10c.exe with partial success. It will allow me to map drive letters, read directories and even create files.

However, if I try large volume copies, it sometimes errors on certain file types - this is a major problem. It failed on a CVS directory last time but I was unable to determine which one or why.

So I'd really like something that works faultlessly - this is data and unlike wireless/desktop/games/etc ... fault tolerance is zero.

ext3 is backward compatible with ext2. they are in essence the same file system. just one has a journal that is saved for the kernel and the other doesent. You can actually switch between the 2 in linux by removing and readding the journal at will. So the driver works for both of them. Ive had issues with this driver in question tho installing programs from windows into the ext2 drive but its not a major issue.

I've settled for ext3

Thanks for the advice everyone.

I've now got a 250G iomega external hdd attached to my NLSU2 on disk1.

I'm using ext3 and have succesfully copied 25G of data from XP over USB by using the previously mentioned Ext2IFS_1_10c.exe.

So ... I'm happy. Sort of.

I's not a solution I would give to other people under warranty.

I've had 2 very specific problems when copying data from ext3 to ntfs (i.e when the ext3 hdd is attached to the XP machine via usb).

1. It cannot copy files (crashes) with '$' in the filename - I think it tries to recurse.
2. It struggles (crashes) with files containing ':'. I don't fully appreciate or understand this one.

----------------

Linux community needs two task forces :

1. Get Wireless working 'out of the box'.
2. Enable _faultless_ transfer between ext3 and ntfs/TxF(vista)

... or Linux will go backwards very quickly.

You cannot create files in NTFS with a : in the file name in windows XP? and as far as I know $ files are system files and dont need backed up anyway. All this file system nonsense i belive in the future will be void as the harddrive is a dying technology closeing on its limits quickly.

Hopefull in the future the seperation between ram and storage will be a vitual one and not physical due to magnetic ram.

I have had some serious problems using this ext2 driver .
One day, after using this, I lost all my permissions settings on my ext3 filesystem system.
USE WITH CAUTION!!

nx5000 : That's why I'd never offer it to someone else. I've already had 2 scary fsck moments after plugging into XP and using that driver!!

exvor :

1) The ":" & "$" situation should not be a problem though. If the files exist - whatever they are - I just want them copied. I don't want to have to think about interpretations which can be subjectively made by each OS. Like the old Nike advert says : "Just DO IT!!".

2) if you're referring to the quantum uncertainty principle then I believe we are a little way from that hurdle just yet... :-)

You've complained about it, now go do something about it.
For FOSS to work *you* will have to show your support.
The bare minimum would be submitting a bug report IMSNHO.

unSpawn : I have mailed the following message to info@fs-driver.org

Hi,

I'm using a Linksys NSLU2 NAS device and have opted for ext3 as the filesystem on my external HDD (sensible, I think).

I've been using your ext2 driver utility (version : Ext2IFS_1_10c.exe) as it is very useful for accessing ext2/ext3 filesystems. As far as I'm aware it's the only one with write access.

I do have a couple of issues which I'd like to submit to you and hope you can advise/rectify.

1. It crashes when I try to copy any files containing the chars "$" or ":".
2. I often get filesystem errors after using it and reconnecting the HDD to the NSLU2 or to a Linux server.

Many thanks!
So I've taken your advice.

I was trying to find a _useful_ ext2/3 filesystem driver for XP. I was inviting comments from other members in the forum and also advising of the problems I had encountered - to warn people if you like.

I thought that this was the purpose of such forums.

Since you obviously feel that I was labouring a point - then please will you tell me why?

My latest post regarding ext2fs was in reply to exvor who had stated that files containing ":" and "$" were not valid files to copy. I was _exploring_ the option that he was correct and as such, had not considered this to be a bug. That is why I had not sent this in a formal report to the author(s) of ext2fs - otherwise criticisms abound in relation to unnecessarily posting to authors concerning features which are not bugs.

I have posted to authors on 2 previous occasions which have resulted in a satisfactory outcome.

I thought I knew what I was doing until I read your post.

I too have been looking for a better solution as fat32 is a dog when it comes to permissions and stuff and the ext2 driver in windows is very imcompleate. Hopefully vista can smooth my woes with windows but probably not knowing Microshaft.

Why do you need to exchange/modify files with permission?
I mean if you have windows, you can access some linux files as read-only (only to view some files) but otherwise I don't see a reason to write on a linux fs from windows?
If you want to exchange downloaded things, go with fat. Linux can set permissions on the mounted vfat system. It's simple and supported from both sides as read-write (well, file size can be a limitation under fat..)

In my case I wanted a univeral home parttion where my home for my user could be the same drive in linux and windows. So this is why i neede permissions other then what fat can provide. Ive since choped up the drive on that laptop so its not really an issue for me anymore. full ext2 file system support in winders would be nice but i can live with what we have now.
