/*
NOTE: storage_idle_notify usage notes..
1) The callbacks are called in the ata thread, not main/your thread.
2) Asynchronous callbacks (like the buffer refill) should be avoided.
If you must use an async callback, remember to check storage_is_active() before
accessing the disk, and do not call any functions between that check and the
disk access which may cause a yield (lcd_update() does this!).
3) Do not call any yielding functions in the callback.
4) Do not call storage_sleep in the callbacks.
5) Don't Panic!
