Slackware 13.37, mv (GNU coreutils) 8.11 On an ntfs file system I had a directory containing almost 9GB of subdirectories and files.
Started to move entire thing to a different ntfs file system, realized I should have copied it instead, so Ctrl-C'd the mv. When I then tried with cp, I discovered that the source directory is now empty, about 7GB of data has vanished
