I'm using version 12.10. When I do large file copy from windows network share it always hangs the copy process. Rest of machine is fine, just the copy process is hung. I connect to the share by launching home folder then clicking on the network section. From there I can find my windows share. I'm finding this very annoying as I have over 2tb of data to migrate from my old windows environment to Ubuntu.

Samba? If so... samba is slow. Broadcasting to find computers on the network is never quick.... If this is a 1 time copy: yry with FTP or SSH. – Rinzwind Apr 10 '13 at 7:58

To me it sounds like a case for rsync; there you can just resume the copy process in case it hangs or you have to reboot inbetween or whatever causes interruption.

rsync -avz -r --stats --progress --perms --links /windows/files/ /home/user/migrated/

The copy process itself is a bit slower, one should mention.

Had the same problem. Setting the io scheduling priority to 3 (idle) works for me. Issue cp command as:

ionice -c 3 cp fromFile toFile

So it means that the program could be waiting for too long and somehow exiting.
