If all else fails depending of the file formats of the files you want t=

recover you can also try some of the forensic tools like photorec from=20
testdisk or foremost. I believe there is a third one. This should get y=
ou=20
the files, although the filenames and directory structure will likely b=
e=20
lost. And it takes quite long on higher capacity or slow drives.

With photorec I managed to recover 100 images from a smartmedia card th=
