Here is the website for the TestDisk and PhotoRec software that
was used to recover your flash drive in Linux at our last LinuxChixLa meeting at
Philippes:
http://www.cgsecurity.org/wiki/Main_Page
It is also available for Windows and Mac OSX.
To install and run TestDisk and PhotoRec In Ubuntu Linux:
“sudo apt-get install testdisk” from a terminal and then run
“sudo testdisk” or “sudo photorec”
Both the photo recovery program and test disk are included in the
debian package.
The PhotoRec software is what was used to recover the files off your
dead flash drive. It will recover many types of files, not just multimedia 
The detailed instructions for running PhotoRec are demonstrated on the
PhotoRec main site:

TestDIsk/PhotoRec is usually faster at data recovery than Ddrescue, but
Ddrescue is more thorough and efficient:

Ddrescue and fdisk is what I always used to use until Chad gave us the heads-up
on TestDisk
Knoppix Linux Live CD has TestDisk/PhotoRec and Ddrescue already installed!
Here are the instructions for using these utilities in Knoppix:

The Ubuntu Rescue Remix Live CD (http://ubuntu-rescue-remix.org/) is also a great option. It includes TestDisk and Ddrescue as well.
And the Ultimate Boot CD (http://www.ultimatebootcd.com/), one of my favorite
boot cds, includes TestDisk as well.
