I think the disk on Linux do not spin down because the OS is touching the disk every so second for log or other things. Just install a fresh Ubuntu with no special options and boot it. You will see disk activity every x seconds even when the box is idle. On FreeBSD however there is almost no disk activity if a box is idle. So the disks is not touched for 25 seconds and the disk will spindown. If you are using Western Digital disks, there is a utility you can run to disable this feature or give it a timeout large enough so the os has touched the disk. It has been a long time since i used it and if i remember it worked only in DOS or windows. Just use google and search for your disk and disable headparking. regards Johan Hendriks
