Help a very newbye

Hi all (and excuse me for my bad english)

where i work its a old pc with installed qnx (i think its qnx2) and we
use to save our data on 5 1/4 floppies.

Now its impossible to read one of those floppies with very important
files on, so i really hope that someone can help me…
its a utility under qnx like checkdisk to repair bad tracks? and its
possible to read those disks formatted with the file system of qnx under
a pc (ok obviusly having a 5 1/4 floppy disk)

thanx for the help

please if u can answer send me the answer via email too, my address is
