Somebody asked if the data is on the platter as soon as the write returns, so I said that's not necessarily the case depending on the disk's electronics (options). * Some of them are said to * even write back their cache if power fails, using the spindle's * momentum to generate the required power. That's nice to hear. :) Satoshi
