I'm getting some file loss and corruption on my Win7/Ubuntu 12.04 dual boot setup. I have a large shared NTFS partition. I have my Windows Docs/Music/etc. directories on that file and have the comparable directors in Linux setup as a sym. link. I'm using ntfs-3g on the linux side of things to manage the ntfs partition. The shared partition is on a logical partition along with my Linux /home / and /swap partitions. The ntfs partition is mounted at boot time via fstab with the following options:

 ntfs-3g     users,nls=utf8,locale=en_US.UTF-8,exec,rw

The problem seems to be confined to newly created and recently edited files. I have not see data loss or corruption when creating/editing files in Windows and then moving over to Ubuntu. I've been using the sync command aggressively in Ubuntu to try to ensure everything is getting written to the HDD. I do not use hibernate in Windows so I know it's not the usual missing files due to Hibernation problem. I'm not seeing any mount related issues on dmesg. Most recently I had a set of files related to a LaTeX document go bad. Some of them show up in Ubuntu but I am unable to delete them. In the GUI file browser they are given thumbnails associated with files I created on my last boot of Windows. To be more specific: I created a few png files in Windows. The files corrupted by that Windows boot are associated with running PdfLatex on a file and are not image files. However, two of the corrupted files show up with the thumbnail image of one of the previously mentioned png files. The png files are not in the same directory as the latex files but they are both win the Document Folder tree.

I've had sucess with using NTFS for shared data in the past and am hoping there's some quirk here I'm missing and it's not just bad luck. On one hand this appears to be some kind of Windows problem as data loss occurs when I boot to Windows after having worked in Ubuntu for a while. However, I'm assuming it's more on the Ubuntu end as it requires the special NTFS drivers.

Edit for more info: This is a Lenovo Thinkpad L430. Purchased new in the last month. So it's a fairly fresh install. Many of the files on the shared partition were copied over from a previous NTFS formatted shared partition on another HDD.

As requested: here's a sample chkdsk log. Some of the files its mentioning were files that got deleted off the partition while in Ubuntu. Others were created/edited but not deleted.

I'd like to see the output of check disk from the windows side before I make any further judgement. Boot Windows. Schedule a check disk using the following chkdsk /f /r /b C: and then reboot. Instead of booting to Windows, boot to Linux and change some files on that partition. Boot to windows and do your best to capture some of the output. Report back if any fixes were applied. If so, repeat the procedure without booting Linux. –  Huckle Sep 16 '12 at 0:28
    
FYI: I "fixed" this problem by reformatting FAT32. –  Logan Mayfield Oct 6 '12 at 0:44
    
Are you now able to create/edit files in Linux? If so then a corrupt file system is likely your culprit. –  Huckle Oct 7 '12 at 22:50
    
Yes, as expected, I've had no problems with FAT32. I had previously used NTFS in Ubuntu without problems, so I was hoping to figure out why this particular configuration was acting up. However, I didn't really have the time to dig much deeper and just went with the more stable FAT32. –  Logan Mayfield Oct 8 '12 at 14:59
    
You should answer your own question then and mark it as complete. –  Huckle Oct 9 '12 at 2:44

Ubuntu is not responsible for the ntfs drivers. Ntfs in linux has always been buggy for me - works for a little while, but corruption does eventually occur. Ntfs is not open source, and the implementation on linux is merely a best attempt at making it work. I now mount ntfs as read only, and if I need large file support for a shared drive between the two, I use exFAT. exFAT works flawlessly on both, and requires no extra setup on Ubuntu or Windows to use.

Interesting. I haven't experienced any problems with ntfs-3g yet. I have a 1TB NTFS hard drive that is full to the brim with no problem at all from Linux. –  trusktr Feb 12 at 6:36

I fixed this problem by avoiding it and using a FAT32 partition as opposed to NTFS. I've had zero problems with FAT32. I don't know that this is necessarily an answer to a problem as much as its a work around, but if you find yourself in
