Just to obtain some empirical data I have connected a usb 3.5 FDD unit
to my CentOS-6.4 workstation and inserted a previously unused 3.5
HDFD.  The Nautilus system automatically opened a window on my desktop
and I was able to copy and removed files from the diskette without any
difficulty.

A peek into /media shows this:


# tree /media
/media
└── disk

1 directory, 0 files


While /etc/fstab shows me nothing that obviously relates to the fdd:


# cat /etc/fstab

Mount on the other hand shows this:

(rw,nosuid,nodev,uhelper=udisks,uid=500,gid=500,shortname=mixed,dmask=0077,utf8=1,flush)

And udisks show this:
