/dev/hdb1 volume shown on destop after upgrade

[vitko]

After last upgrade of my Debian (Sid) new hal 0.5.7 arrived.

I was surprised to see new 60 GB volume icon on my desktop,
it is /dev/hdb1, referenced in /etc/fstab like

    $ grep data /etc/fstab
    /dev/hdb1   /mnt/data   xfs   defaults   0   2

Maybe it is some Gnome magic and not a hal issue, so I'm
sorry for OT. But I'd be very grateful to learn how do I
keep my non-removable volumes hidden from my destop? I'd
like to have only removable (USB or IEEE1394) ones shown
there.

Thanks for any tips.
