Actually, that can be done. Your local pet store should carry a digital thermometer with a corded sensor (normally used to measure the temp inside a reptile terrarium with readout mounted outside).
I do have two questions, though.
1) Why is temperature such an issue? If the drive is mounted in a normal drive bay, it shouldn't overheat unless a cooling fan should fry, at which time the mobo and other boards would be at much greater risk of damage.
2) Exactly how old is that drive? Even my 16g Western Digital had S.M.A.R.T.
