[PLUG] Share error?

[Denis Heidtmann]

I clicked on the Floppy Disk in the Files GUI (Nautilus replacement, I
believe.)  The following window popped up:

Unable to access "Floppy Disk"

Error mounting system-managed device /dev/fd0: Comand-line
'mount"/media/floppy" exited with non-zero exit status 32: mount: /dev/fd0
is not a valid block device

The drive was empty, so it may always respond this way.  But then the
following popped up:

There was an error while getting the sharing information

'net usershare' returned error 255:net usershare: cannot open usershare
directory /var/lib/samba/usershares. Error No such file or dirctory
Please ask your system administrator to enable user sharing.

I have done no explicit sharing.  Is this a bad sign?

Thanks,
