moved and lost files from ntfs hd

Hy there, I tried to move several GB of files from an external ntfs hd to a storage card. At some point an error message popped up and all moved files were neither on the target drive and nor on the source drive anymore. I am not a very experienced Ubuntu (and Linux) user you see, so having experimented a while with the common recovery tools I am rather puzzled an worried...
Any chance for a rough guide on what to do
Thanks Michael

Well, first off, try running

Well, first off, try running Photorec on the external drive. If the NTFS partition has not been changed since the move that resulted in the files being lost, then pick the option to search the filesystem's unallocated space. This will look for deleted files.

Post what that turns up and we'll take it from there.

Hy Andrew, and everybody

Hy Andrew, and everybody reading, I'm currently running photorec and it really seems to restore a whole lotta files ;o) in an unconvenient format, though (names are several random figures), but really I'm very relieved and happy about that development, thanks! If you should know any tool that'd restore the former names etc, I'd be happy to try it. Thanks for the quick reaction!

Hi Michael. You can rename

Hi Michael.

You can rename some files. Others you can sort by size.

Also, you can try ntfsundelete. But I find it doesn't often pull out the file names.

Just try running

sudo ntfsundelete -p 100 /dev/

and see if it prints out file names in the right column. If it does, then you can run it and recover those files.
