I am not familiar with the 'ext2 volume manager.'
But maybe you should try checking the site for any bugfixes, and definitely report your issue to them as they are responsible for this program.
I have copied from and to an ext2 partition under windows, but I used a different driver(?) from www.fs-driver.org
, so try uninstalling the 'ext2 volume manager' and try installing the ext2 driver from the site I mentioned. Perhaps you might be able to transfer your file successfully, (also remember during the installation to enable large file support).
Hope this helps.
