The recent, informative recent post by davidz about the new storage handling in GNOME helped me a lot in understanding the error message that scared the shit out of me when trying Fedora 11 Preview (with a LiveUSB) on my Eee PC.
It was instant panic when I saw it, so obviously I was in a hurry to see the details:
There is an one single error: the hard drive temperature at around 50°C and I calmed down a bit. Later searched a bit on Google and it looks like this is an usual hard drive temperature for netbooks, where the ventilation is limited. Pretty much like a scary false alarm (but maybe I am just ignorant here).
Overall, the application could be, IMO, better worded: even the item passing the test (green dots) are labeled "Pre-fail" making you feel something bad is going to happen.
I don't know, maybe this is a philosophical view: anything living is going to die and anything working is going to fail, life is pre-death and working is pre-fail.
