Not really. SMART Command Transport is a feature, introduced long time ago. The last Seagate desktop drive model, not implementing it, is Barracuda 7200.10 (that's from year 2006), while WD and Hitachi had it even earlier. Besides, smartmontools version 5 behave as you expect it should (just checked that). So, the hypothetical problematic drive must be very old, but reused in fresh system, and also must be affected by long timeouts. Not very probable mix, IMHO.
