Jens' ATA7 parking code is a great start but we still have a couple of issues to address before it's usable for this purpose. (1) it only works on a subset of the devices that the Windows driver works for, and (2) we need a way to freeze the device for a short period so that the next I/O request doesn't wake it up before it hits the floor... > The problem here is that we have 10 different models. > > One will have 20 as X and the others will have 500 as x.

If there really are devices with resting values of 20 then I would agree we have a problem. I've tried on a few different Thinkpads and have always seen resting values of several hundreds. If this is true for all, I would like to think we could estimate a sensible value that works for everyone...
