NTFS Write support not working in Laptops


hi there,

I am using a slackware 10.2 in my IBM Thinkpad A31. I recompiled the kernel from source using 2.6.16.5. Everything went fine except the NTFS write support. Any help will be greatly appreciated.

We had a question on this a few weeks ago, and I think everybody agreed that NTFS write is not supported. Did you check this forum?

thnx for your suggestion dear Mr. Randux.. well i understand that people here dont get paid for helping others. But this is phenomena over here isnt it. You get what you put in and people get what they deserve. Well bout my problem i am using this damn NTFS write support in my home PC perfectly with the same kernel 2.6.16.5. i just want to know if there is any discrepancy while using this NTFS write support with portable hard disks like that. Well anyways thnx for replying...

So you open a thread saying that "everything went fine except the NTFS support." And in your last post you say it's working perfectly.

So I guess you just like hearing yourself type! Have a nice blog.

He said it was working fine on his desktop. I think?

Anyway, its a kernel option, did you include NTFS write in your kernel? I myself leave it out cause I do not want to corrupt windows data, which I am told can happen, so use it at your own risk I think is the general thought.

Seems like nobody is exactly reading the OP's posts.

1: Has the same options/same kernel on a desktop and a laptop
2: NTFS write works on desktop, not on laptop.
3: Wants to know why

OK...Little more info first. How about
Code:
cat /proc/filesystems
And
Code:
cat /etc/fstab
Also, what type HDD are we talking about, and where is it mounted?

PS. Sorry about the previous posts. I beleive they just misunderstood you. Also, more information is always better....

If you look at the opening thread, there's only the statement that everything works but NTFS write support. There isn't any desktop/laptop issue stated.

The rest of the "info" started trickling in after he freaked out over my .sig (which was not directed at him).

Must be the thin air.

Dear All,

Thnx for replying my post. Anyways i am not here to create any trouble or make any one feel bad and hope u people also think like that. I just wanted a little help with my system over here. I want to say something to Mr. Randux,.. pls dont feel bad for any of my words. Actually i think you haven't looked at my subject in the first post. From the very beginining i was talking bout laptops not desktops.

Well well well,,, i would like to provide you people some information bout whats goin on in my system. The following are the contents of /etc/fstab and /proc/filesystems respectively..

Code:
/dev/hda8        swap             swap        defaults         0   0
/dev/hda10       /                ext3        defaults         1   1
/dev/hda7        /boot            ext3        defaults         1   2
/dev/hda9        /home            ext2        defaults         1   2
/dev/hda1        /windows         ntfs        ro               1   0
/dev/hda5        /failsafe        ntfs        users,rw,umask=0 1   0
/dev/hda6        /zte             ntfs        users,ro,umask=0 1   0
/dev/cdrom       /mnt/cdrom       auto        noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0


Code:
nodev   sysfs
nodev   rootfs
nodev   bdev
nodev   proc
nodev   binfmt_misc
nodev   sockfs
nodev   usbfs
nodev   pipefs
nodev   futexfs
nodev   tmpfs
nodev   inotifyfs
nodev   eventpollfs
nodev   devpts
        ext3
        ext2
nodev   ramfs
        msdos
        vfat
        iso9660
nodev   nfs
nodev   nfsd
nodev   smbfs
        ntfs
nodev   autofs
        udf
nodev   mqueue
nodev   oprofilefs
nodev   rpc_pipefs


As you can see in the fstab there are altogether three ntfs partitions in my harddisk. ohh about my harddisk...its an IBM Travelstar of 40 G with 3 partitions of NTFS each of around 10 G. Wait i will provide you the partition information too.
Code:
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda10            7.1G  3.4G  3.4G  50% /
/dev/hda7             101M  9.4M   86M  10% /boot
/dev/hda9             1.9G  453M  1.4G  26% /home
/dev/hda1             9.8G  5.5G  4.4G  56% /windows
/dev/hda5             9.8G  5.6G  4.3G  57% /failsafe
/dev/hda6             8.0G  3.6G  4.5G  45% /zte

well right now what i have done is mounted the failsafe named NTFS partition as readwrite and left the other two partitions as read only. I have compiled the kernel 2.6.16.5 with NTFS write support as a kernel chunk but not as a module..

keep in mind that I dont know what I'm talking about yet, but I thought the umask comment in your fstab needed to be "umask=000". Does it make a difference if you change that?

what utilities are you using tor NTFS writing ?

try using ntfsprogs

http://wiki.linux-ntfs.org/doku.php?id=status

they provide better support than the new kernel driver. I have used QTparted which uses these utilities to resize my ntfs partition.

It worked without probs. The support is very reliable, it will refuse to write if the writing is not possible.

I hope this helps.

EDIT: i used it on my laptop, and anyway this doesnt matter.

nope, umask=0 is fine, I use it that way (on fat32 partitions)

let me ask you, WhiteDevel, why do you have to mess up with NTFS partitions? Those are slow, clunky and difficult to keep sane, and most important to me: are not properly supported by linux (read the help on the kernel write-capabilities on NTFS), it's very experimental, unstable and coming from Micro$oft I just won't trust to put my data on it.

I you need to access data on both your windoze and your linux systems, why don't you put it on FAT32 partitions? Not fast, not better than ext2 but stable and well supported at least.

just my

Alternatively, go the other way and use the ext2fs driver for Windows =)

http://e2fsprogs.sourceforge.net/ext2.html

That's not exactly a solution to why things are not working on the laptop, however. As cwwilson has stated the problems precisely, let's borrow his list and have a look at them =)

1: Has the same options/same kernel on a desktop and a laptop

Ah, correction - has the same KERNEL on desktop / laptop - forgive me, but I don't see anywhere that both kernels are configured the same. Could you, WhiteDevel, please check you've got the same parts for ntfs write support built in your laptop kernel? Could be as simple as missing an option somewhere. Sounds like you know how to do this, so I won't patronise you

2: NTFS write works on desktop, not on laptop.
3: Wants to know why

Could be due to a misconfigured kernel or a piece of software that's missing/incorrect. I doubt, seriously, it would be a hardware problem. Hardware does not distinguish between filesystems, it tends to only care about raw binary data.

What sort of errors are you getting when you attempt to write to that RW partition? Anything that shows up in dmesg or /var/log/messages might give you some help, too.

Perhaps borrow your desktop config as a starting point for the laptop kernel and build another one and see if it makes a difference?

Let us know how it turns out,
- Piete.
