[ale] Errors & Celsius, WAS: Re: Spinrite, or BIOS, or something drops hdd error rate 5X

I'd surmise that one temp is being taken on the board close to the edge 
and that the other is being taken inside the enclosure...but >100C 
sounds a little oddly high but maybe that's normal for a very limited 
area in there.

By the way...

<pedantry>The only way you can say one temperature is "twice" another 
numerically is if you are using Kelvin and not degrees Celsius or 
Fahrenheit.</pedantry>
