I have a dual boot installation with Windows 7 Ultimate (32-bits, NTFS file sytem) and Ubuntu 10.10 (32-bits, ext4 file system). I have installed the version 7.0a of Truecrypt in both Operating Systems.

Located in the Windows 7 HDD I have a 150 GB encrypted file container. It is a standard and dynamic file container, which means it's not hidden and uses a sparse file. This file was created using the Windows version of the Truecrypt program. When I logon in Windows the container is mounted as the drive E: and everything works fine!

In Ubuntu the Windows's NTFS file system is automaticaly mounted after I logon. I've configured that using the ntfs-config package. In my ~/.profile I have this line to mount the truecrypt's file container:

truecrypt /media/7EDEBCFADEBCABB1/Users/Wagner/hd/hd.tc /media/truecrypt1

The file container is mounted after the logon without any problem. I can access it, copy files to/from it, etc. But when I try do copy relatively large amounts of data (>~50 MB) to it via nautilus or cp -R, it starts the copy, copies some data until certain point and then it just hangs! The progress bar does not move anymore and nothing happens. There is no error, it just hangs and that's it. I have to kill the process myself.

This problem does not happen in Windows: I can copy very large amounts of data to the container and it works great. But in Ubuntu the problem always happens! I mean, whenever I try to copy a bunch of files together the copy process hangs.

Does anyone ever faced this problem? Can anyone help?

Thanks!
