NOTE: ata_idle_nofity usage notes..
1) the callbacks are called in the ata thread, not main/your thread.
2) Asyncronous callbacks (like the buffer refill) should be avoided.
If you must use an async callback, remember to check ata_is_active() before
accessing the disk, and nonot call any functions between that check and the
disk access which may cause a yield (lcd_update() does this!)
3) Do not call cany yielding functions in the callback
4) Do not call ata_sleep in the callbacks
5) Dont Panic!
