SMART can be done just as well by software as by hardware.

Drives that mysteriously stop and start working as you move them around are
not uncommon. It's a fairly typical symptom of failing hardware that any
sort of bump may cause the problem to appear or disappear (consider the
practise of hitting a failing TV).
I think that if Adaptec had some advanced method of recognising a failing
drive then they would boast about it in their marketting documents.
