Oh, and btw, last time I had an issue with varying drive sizes, I had two drives in a MD mirror on a Sun^WOracle box (X2100 M2), and the new drive that arrived from Sun^WOracle, was *smaller* than the other one, even though one of the argument I've heard for buying overpriced drives from Sun^WOracle, was that they tuned their firmware to cap their drives to always expose the same amount of sectors. I guess that was just marketing BS. I ended up reinstalling the box…

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
