hard drive parking was already sorted out. We have a script that does this and works great parking the heads. Would have to disagree with you here. 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

Thanks to development of the driver from some nice guys, we are able to get data from the accelerometer. There is one problem. How do we calibrate the values that are outputed from the userspace? All PC's get a different value, and we can't really find the best solution. What is the scientific a

Well don't forget there is a bios 'calibration' routine that you will see on start up (especially if you are on a moving vehicle/train). What is this calibration used for, and does it provide calibration information to the windows driver? Could we use it somehow to help solve this problem? Yani O
