Anyway, can someone explain me rationale of unmounting/cutting microSD card on removing cover? There is one at all, or designers just thought that users are idiots and will remove card hard-way when in use?
I queried this in another thread (I think the one on moving swap to the SD), because forcing an unmount can't be good for the filesystem on the card since it may take several seconds or more to flush cached data to the card and if the filesystem driver is not given time to do this the filesystem won't be left in a clean state. Anyway I got a response from joerg_rw who was of the opinion that it could physically damage the micro SD card if you removed it while the slot was still powered.
