Realistically no ... unless someone comes up with a reliable heuristic
to give us the size.

This is a stopgap: your 3TB drive can be guessed as the 16 bit capacity
plus 2TB, but the same won't happen for a 5TB device. Believing the
partition table gives us a chicken and egg problem because something
still has to get the partition table on to the device.
I don't think "don't buy something that doesn't work" is a hugely
unreasonable response to this.
