Hi,
One way to figure out what is causing the disk access is to get the kernel to tell you:
echo 1 > /proc/sys/vm/block_dump
Then, monitor dmesg output or equivalent. Before you do this, you might want to disable things like syslog (in case such messages get written to your syslog, then syslog needs to write to disk, which then gets logged again, etc... needless mess that can be avoided). When you're done, just:
echo 0 > /proc/sys/vm/block_dump

I have two (2) hard drives in my FC3 box, and my second drive is as loud as a buzz-saw. It's my "scratch" disk and I don't use it often, so I use the hdparm command to keep it from spinning when not in use. This method worked fine with FC2, but with FC3 something causes the drive to spin up every 15 minutes. I've looked through my cron entries and can't find anything. What could be causing this?
