retrieving data from corrupt floppy?

My brother is trying to recover data from a crashed hard drive. He has a backup on a floppy for an important file, and is using Norton to try to recover it, but Norton Disk Doctor says it can't recover the data unless it has room on the floppy. He's stuck; any ideas? Any way around this to recover the data on the floppy?

Thanks!

 

I should have mentioned...the floppy as bad sectors on it, and the backup file takes up the whole floppy, thus the problem with NDD not having room to recover the file without any room available....any ideas? I don't know diddly about NDD...

 

Are you sure there is only one file on the floppy? It is unusual to have only one file and it take up every last cluster on the floppy.

If you do have more than one file on the floppy, try copying one or more of the files from the floppy to another disk. Then delete the file(s) from the floppy that you were successful at copying and then try to recover the file(s) that is/are left.

That is all I know to tell you right now. Perhaps someone else can come across with more help.
