Saved by the icon, no. 5.

David, thanks for the fine work on the new disk utilities in GNOME. You saved my hide, because I found that the hard disk in the machine my wife and kids use was getting pretty dodgy after 3.5+ years of running time. $45 and 320 brand-spanking new gigabytes later, everything’s A-OK. (Using rsync made restoration a flash.)

Paying attention to that little disk warning icon in Fedora 12 saved me and mine a lot of time and unhappiness down the road.
