Undelete files of a fat32 fs from GNU/Linux
Most usb mass storage media devices, including digital cameras, use a FAT32 filesystem to store its data. That’s mean that even when you just use GNU/Linux filesystems like ext2 or ext3 in your system, if you have an USB pendrive, camera, etc. you’ll be using also FAT32 filesystem within those devices.
I’ve a Nikon D60 but also a Sony Cybershot that I use for take fast pictures, as it fits in a pocket. This afternoon I lost some important pictures that I’ve taken since Dec./2008 -yes, I should dump my pictures from camera to PC often, but…- when I was copying them to my laptop.
I started to search for a recovery tool that I could use in Linux, and finally I’ve find it: TestDisk, a powerful free data recovery software. I’ve it installed on my Kubuntu before, and I did not know it. It did recover all my pictures, and its not just free as in “free beer”, is FREE as in “free spech” 
Thank you very much for this post!
Using TestDisk I was able to recover ALL my pictures from my digital camera that I accidentally deleted.
