The kernel doesn't currently do spin-down at all, does it? Andrew, are you planning to change this? I'm not a kernel programmer, but it seems like a good idea to me: The kernel could flush writes as usual while the disk is spun up, but still spin down after a bit if the rate is low enough. The disk would never spin itself down in that case. Maybe there are also cases where the kernel would delay spin-down, if it hasn't started writing but thinks it might soon.
I'm excited to try this. Thanks for writing it against 2.4!
