Hi, what would be the best approach to implement aps on FreeBSD? I got an Accelerometer driver which will deliver data. First Version is available at https://sourceforge.net/project/showfiles.php?group_id=138242&package_id=160977 We have to poll the device for information quiet often to detect a possible shock early enough to park disk drive heads. What else must be done to prevent a possible data loss? There is also an discussion about that concerning linux. http://sourceforge.net/mailarchive/forum.php?forum=hdaps-devel Would an daemon be sufficient for that? Reaction time? What about an kernel thread? Other solutions? thanks in advance Maikhelp
