Great work with KnoppMyth. It is really a perfect show-off example of what you can do with Linux.

I have finally a box up and running relatively stable (fan-less Mini-ITX EPIA 10000 with a single PVR350).

It does actually look nice in the living room under the TV. And my wife has even accepted it :-)

A couple of problems remaining. The most urgent is noise and heat. A major source for both is the harddisk.

Has anyone tried (succesfully) to shut down the harddisk while the system is not active ?

I have tried to dash "- " all the log files in syslog. I have killed mysql.log. Does not help.

Disabled swap (½GB RAM)

apt-get and installed noflushd

The best result until now have been to stop mythtvfrontend, backend, mysql and apache.

I have run the following commands:

Find files written within the last 5 minutes. Result "Empty"
find / -cmin -5 -type f -not -path "/proc/*"

Find files accessed within the last 5 minutes. Result: "a few libraries", but they should be cached ?
find / -amin -5 -type f -not -path "/proc/*"

hdparm -S 2 /dev/hda

will turn off the harddisk after 10 sec, but it only last for perhaps 30 seconds, then it starts up again.

I am aware that a lot of people do recommend leaving the harddisk running, because the spin-up cost heavily on disk life time. However the heat will kill it first, and if not, then the noise will when I throw it out of the window :-)

Does anybody know of a really silent harddisk (> 120 GB) ?

from what I've heard the seagate drives are the quietest, but I have never used one myself, also most people recommend going with the 5400 RPM drives to reduce noise, a suggestion that came a bit late for me :cry:
