Your consultant is not a very good consultant, then. If you live near a
city with >= 100,000 people or a city with a college in it, go Google
for "$CITY Linux user group" and see what you find. The people there
will probably be able to solve the problems you're having in an hour if
you bring the machine in.

Nautilus has no real advantages over Konqueror or mc or bash, and if you
prefer bash, by all means use it.

??! Fire your consultant and get a competent one. All you need is a
line like so in your /etc/fstab :
/dev/hda1 /mnt/somewhere vfat umask=000 0 0
...since "noauto" isn't specified, the partition will be mounted at
boot. umask=000 makes it so that any user can do anything to any file
or directory. Replace /mnt/somewhere with the directory where you want
the Windows partition to be mounted. /dev/hda1 is almost certainly the

? This is out of date AFAICT from looking at the code for mount.

It shouldn't, unless the floppy disk itself had its write-protect tab in
the "read only" position.

Because /dev/hda0 doesn't exist?

Which GUI? There are a bunch of front-ends to cdrecord, and the one
that works best IME is k3b. If reading's all right but writing isn't,
you need to post the output of "lsmod" and "cdrecord -scanbus".

Yes. If you have an fstab entry with "user" or "users" in the options
field, any user can mount/umount the partition/disk. If there isn't an
fstab entry, only root can mount/umount it.

Ah. That's for manually specifying the FAT size (12, 16, or 32 bits.)
This is not usually useful and can be dangerous, since the structure of
FAT is well-understood and autodetection is easy. Floppies always have
12-bit FATs, partitions are 16-bit if < 2G and 32-bit if > 2G.
