Tom,
You did what I expected. Uninstall is correct, as it's the same as remove.
I'm running out of ideas, but I can suggest two more things to try:
1. Review an error report that Vista produces: Start > All Programs >
Problem Reports and Solutions. Peruse the report and note any errors
contained in the report. Focus on that part that suggests corrective
solutions for any errors.
2. If you are using a burner program, such as Roxio or Nero, they could be
causing a problem with your CD/DVD-ROM drives, but I don't know how that
would effect the floppy drive. In any case, as a long shot, this same page
her on this forum contains posts about people having their optical drives
disappear. The answers to those posts recommend that some entries in the
registry be removed to correct the problem. Take a look at those posts, and
note the Microsoft KB article that instructs on how to remove the upper and
lower filters.
If we can't resolve your problem here, you could try contacting Microsoft
support directly for some "official" help. You can learn how to do that by
visiting the Microsoft website and looking for instructions on how to obtain
help.
Another alternative is to contact support of the vendor of your computer
(Dell, HP. Compaq, etc.), especially if your computer is still under
warranty. They may or may not provide warranty support, but even if they
won't, it's something to think about.
Anyone else?
