A swift Googe shows the 2.5cm drive to be far more common than the 3.5. Is the smaller drive a plug in replacement using standard SATA power and data leads or is there more freakin adaptors to buy?
My 750G drive is not old! It is in fact a replacement from Maplins of a WD drive that went completely T's U (think this is a Samsung actually)but I am well out of the warranty period now.
Anyway, just a whim, what do I need a blindingly fast PC in the living room for?!
