[wplug] floppy disk rescue

[fobitt]

If that doesn't work, make a dd image of the disk as already  
described, and than run it through a tool call foremost. It is  
designed to scrap out files from a dd based on their header info.  
Works really well, and is fairly easy to use. Just modify the config  
file to include the file types you want to carve out.
