not so sure a quick fomat on windows is going to erase all the data. repartioning does not for sure. if you rebuild the partition to what it was before the files may still be there.

think u need to completely reformat. you can do it right from the tablet.. look back a page or two for what i told quick to do with sfdisk.. that wll make 1 large partition and reformat the whole thing into ext2... that should work. or try a full slow reformat in windows.

if they still show up use dd like suggested by someone else in this thread.
