Disable power saving

Hi there guys, running PCLinuxOS 2009.1 on my main machine :

AMD Phenom II 545, 3GB DDR2, ATI Radeon HD 4870 512 GDDR3, 1 x 250GB IDE, 1 x 1x 250 GB SATA, 1 x 160GB SATA, 1 x 500GB SATA.

What I want to disable are the HDD's powering down after a while because when I come back to work at my machine, it is painful to wait for the HDD's to spin up again. I also want to disable the screen from turning off. I have removed DPMS from myxconfig, but it as made no difference. Any ideas?

TIA

I do the opposite in a startup script (.xinitrc or similar) using "xset dpms force off". I'll bet you can find a way to modify that :)
As for the disks, I'd poke around in the bios or the kernel to try and stop that.

about the disks, maybe you can configure it with hdparm?

Possibly you want to use some configuration of ACPI (note the "UPDATE" on linked article)
