Of course nobody with a court order on your doorstep is going to take your word for anything. If the object of the order is to find some data, anything and everything that looks vaguely digital will be taken (consequentially, every physical nook and cranny will be searched for errant micro-SD cards). Stuff is handled on a per-item basis. An item is either returned (after months to years), or not.

If you end up in a situation like that - which does not mean you did anything wrong at all - your best bet at getting your personal data and items back is by 1.) having them physically separate 2.) not encrypting anything or immediately providing passwords / access so items can be cleared.

Effects and results may vary. Consult your local lawyer for more information.
