In the interests of finishing off this thread: Thanks to all who replied to my question on how to get a notebook disk to spin down. The clear consensus is: - the problem was probably caused by the cron daemon (I have some doubts about this, but never mind) - the problem is fixed by adding the "noatime" option when mounting the root filesystem (I use /etc/fstab to do this) - there appears to be no harm in not updating the inode access times with this option. - I am now using "hdparm -S 6 /dev/hda" to great effect; placed in my /etc/rc.d/rc.local file. - Naturally as soon as I learned all this from this e-mail thread, I found the appropriate paragraph in an out-of-the-way spot on the "Linux on Notebooks" pages (this must be one of Murphy's Laws... :) ) - I've added this discussion to my notebook web page in the interest of spreading this gem of information.
