Yeap, SD_TIMEOUT should be it. But I've never personally seen disk flushing taking as long as 30 seconds. Does it really happen? It's not like the drive would be doing random seeking. One full stroke across the platter should be it. Even with the rotational delay, going over 30 seconds doesn't seem very likely.
