[plug] FAT (Flash Card) Undelete

[Timothy White]

I am doing some work at my primary school and have limited access to
my normal tools and environment (so excuse html mail if it comes
through)
The teacher I am working with has accidently deleted a couple 100
photos off a thumbdrive that we need for a graduation presentation.
The thumbdrive is USB 256Mb FAT(32?) and the delete was performed
under windows XP (not in recyling bin.)
I have a Overclocix 3.4 CD as well as a few older knoppix CDs. All the
windows utilities I have found need to be registered to work :(
Does anyone know of a free windows utility or a linux utility on a
standard knoppix or overclocix CD that I can use to recover the files?
Thanks
Tim
p.s. It appears that only one directory has had the first letter
removed while the rest of the files are the names intact. (windows
replaces the first letter of a file name with a $ when it deletes it.)
