No, no, no!

If you have an old floppy that you *need* to recover, *never, ever* do
this! I shall say it again, don't ever attempt to fix a broken floppy
disk before you've made either an identical duplicate - which sometimes
you can, or have attempted to extract data from it!

(This is also true for recovering data from any other media, including
crashed computers, zip drives, etc.)

1. Write Protect the disk.
2. Insert the disk and attempt to read its content.
3. If that fails, attempt a *recover* using Norton/Disk Warrior, don't
attempt to repair it!

The purpose of a desktop rebuild is to make the Finder know which
application to launch when you double-click on a document, and while it
figures that out, it also keeps track of which icon to display for the
document.

When you rebuild the desktop, you are actually writing data to the disk.
This is not a good thing, because for all you know the directory
structure is corrupt and the rebuild happily overwrites one of your
files.

No, no, again, no.

No, no, more no.

If you at first cannot read the disk, this is the preferred first
alternative. Make sure you recover stuff off the disk, *not* attempt to
repair the disk.
