I seem to remember reading here (on WPT) or some other blog, that the reason MS really didn't want use-replaceable memory cards was because of the way memory was to be managed in WP7 (and beyond, I would guess). I remember the article mentioning that WP wants to manage ALL of the memory as a single unit, so it EXPECTS all of the memory it has, to be available all of the time.
This seems to be the case with the symptoms described -- needing to 'hard reset' after adding the new card; the card being formatted so as to be unusable in any other device.
My guess is that trying to find a card which matches the memory characteristics of the internal memory chip may be why some work and some don't. The O/S is trying to manage them all as one larger unit.
