Windows 7 reports files copied by Ubuntu 10.04 as " corrupted and unreadable"

[otakuj462]

Binary package hint: ntfs-3g

I have Ubuntu 10.04 and Windows 7 installed on my laptop in a dual-boot configuration. It seems that files copied from Ubuntu onto the NTFS-formatted Windows 7 partition cannot be read in Windows 7, which fails with the error "The file or directory is corrupted and unreadable." Also, having copied a directory from Ubuntu to \Users\Jacob\Application Data, when cd'ing into the Application Data folder and running dir, I receive the error "File Not Found".

There are many other reports about this problem, some dating back to 2008:

Hi,

What ntfs-3g version are you using ?

I am not sure for Windows 7, which I do not have, but on Vista there is no "Application Data" directory any more, it has been replaced by a symbolic link :

[linux@pavilion2 ~]$ ls -l "/vista/Users/Jean-Pierre_2/Application Data"
lrwxrwxrwx 2 linux root 180 Nov 8 2008 /vista/Users/Jean-Pierre_2/Application Data -> /vista/Users/Jean-Pierre_2/AppData/Roaming

The Vista symbolic links are supported by ntfs-3g since ntfs-3g-2009.11.14

PS The links you reference are related to problems which have been fixed long ago.

Regards

Jean-Pierre

I'm in Windows 7 at the moment, so I can't tell you the exact version, but It's whatever is used by the most up-to-date Ubuntu 10.04.

I didn't know this, but I think it is probably true for Windows 7 as well. I did copy data from Ubuntu into the Application Data directory, which appears to have made it no longer navigable in Windows 7 by cmd.exe, which fails with the above error, or Windows Explorer, which fails with a "permission denied" error, even when run in Administrator mode. Strangely, navigation is possible using Cygwin.

I used these links because they seem to be correctly identify the behaviour I am currently observing. So maybe these issues have not actually been fixed, given that they seem to be occuring on my machine.

Here are more recent reports of what appears to be the same issue:

Hi,

I cannot provide precise help unless I know the exact version of ntfs-3g you use (type "ntfs-3g --help" obviously on Linux).

What you say about "Application Data" seems to indicate that this is not a directory on Windows 7. If you are using an old version of ntfs-3g, you have to put your files into the symlink target (this could be \Users\Jacob\AppData\Roaming, but check this first). Since ntfs-3g-2009.11.14 the symlink is supported by ntfs-3g.

The references you indicate are relative to the object_id file (file nr 25), which Windows uses to track a file which has been deleted from a shortcut still present. This has been fixed since ntfs-3g-2010.3.6 (but the shortcut remains unusable).

If you have another type of problem, please indicate your mount options and the exact steps to get the error.
