I was prompted in early September but since then, no prompts.

I can export and import the pool (Transcend) without entering the 
passphrase.

Is this intended behaviour and if so: how does the pool – or the 
computer to which I connect the device (a mobile hard disk drive) – know 
that entry of the phrase is unnecessary?
