also note that if you are useing IDE drives you have no way of really knowing when the data has hit the platter (as opposed to just being in the buffer of the drive) as many of the drives will lie to you and tell you the write is complete once it hits the buffers.
I think they use capacitors that will hold enough charge to allow flushing the buffers to disk when there's a power loss.
Mea culpa, you're right, David. I was thinking of a controller which has its own write cache and disables the write cache built into the drives.
