Hi everyone!
I am relatively new to Porteus, and not a Linux geek but I manage all the same I would need some help, please.
The purpose:
I'd like to run Porteus from a USB-key (done with YUMI) on my laptop with as less power consumption as possible. So it would be nice to spin off the hard drives for a complete session.
The problem:
To save power I manage spin off the hard drives (hdparm -Y) but although I do not use them, they are unmounted, after say 5 minutes they spin up again.
Others:
-cheat code change=EXIT entered
-copy2ram cheat code in place
-hard drives unmounted
My system:
Porteus 3.1 desktop edition MATE 64bit
Any ideas?
spin off hard disks for a session

Re: spin off hard disks for a session

Code: Select all
nohd
... Do not discover any hard drives during startup.
Code: Select all
noauto
... Do not mount any devices during startup.
Every disk needs to be mounted manually in order to access it.

I've forgotton to mention noauto is already set.
As for nohd, if set it I cannot boot Porteus up, usb-key is not recognized, it's 'mistaken' for a hard disk.

Re: spin off hard disks for a session
Whats the output of: hdparm -B /dev/sd?
A value set higher than 127 probably won't spin down. If it says unsupported it could be that it controls itself (or it is way old).
