1. ntfsundelete - Undeleting NTFS files
Published Blog entry by Raul Suarez
[ http://kwlug.org/node/649 ]

And Linux saves the day again.
My son installed an application but mistakenly he selected the data
directory as the installation directory. When he realized it he decided
to uninstall, but the full uninstall deleted everything from the
folder.
This is: the program and all his files.
The solution was very easy. I found that I had already installed the
ntfsprogrs package. This package contains a pretty slick utility called
ntfsundelete.
This utility allowed me to first list the files that I could recover
and then recover them.
It has some very useful filters such as:

File name pattern matching: For example to search/undelete files *.mp3
Files modified since: Maybe you don't care about old deleted files just
files modified since 5 months ago
Percentage recoverable: In some cases you want to salvage whatever you
can, in some cases you only care if you can recover 90% or more, for
example.
Files within a specific size range

In my case it was a breeze to use it.
I first unmounted the partition where the deleted files were
sudo umount /dev/sda2
I then executed the following to list which deleted mp3 files located
in my /dev/sda2 device that were modified in the last 5 months were
100%
recoverable:
sudo ntfsundelete /dev/sda2 -m '*.mp3' -p 100 -t 5m > deletedmp3.txt 
That created a file called deletedmp3.txt with a list of files. 
Once I reviewed the list I went on to undelete them and put the
undeleted files on my external HDD on a folder called undeleted
sudo ntfsundelete /dev/sda2 -u -m '*.mp3' -p 100 -t 5m -d
/media/externalExt3/undeleted
If you want to know how to fully use this utility just open a console
and type
man ntfsundelete
Important things to consider

If you deleted using the file manager first check if your files are in
the trash can, that's always the easiest way
As soon as you realize that you mistakenly deleted the files, don't
write anything else to that partition. if possible unmount it right
away
If you want to do it in a computer that does not have linux installed,
you can always use a live CD distribution that includes the
ntfsundelete
utility
