unnessary disk access
i just installed Arch Duke some hours ago and then i did "pacman -Syu". everything is running fine but sometimes, 1-3 times a day, i see unnecessary disk-access. when you access the disk e.g copying the files from one place to the other then you can see the red LED of the cabinet (representing the Hard-Disk) glowing.
i did not set up any cron jobs and nothing is running right now but my OS is accessing the hard-disk, continuously for 10 min. why this is happening ?

Re: unnessary disk access
Well, it seems something is running 
I do a guess: have you beagle running?
maybe a dump of "ps aux" would be nice, then we can maybe identify what's causing it...

Re: unnessary disk access
There is a default cron job that runs updatedb daily, you can disable it by removing the file, or changing the permissions (as root: chmod 000 /etc/cron.daily/updatedb) and see if that's the reason, was one of the first things I turned off once I saw it was running.

i think, this is what you are talking about (some part of "ps -aux")

root 19534 0.0 0.1 4216 996 ? S 00:02 0:00 /bin/sh /etc/cron.daily/whatis
and this i from my Arch Duke:
[arnuld@arch etc]$ cat cron.daily/whatis
#!/bin/sh
# Make sure MANPATH is complete
source /etc/profile
source /etc/profile.d/* 2>/dev/null
# Update the "whatis" database
/usr/sbin/makewhatis -u -w
[arnuld@arch etc]$
i think i need to comment that last line, right ?

Re: unnessary disk access
I think you can also just remove the whatis file in cron.daily
