When HDD disable in BIOS. I think PC just turn off for boot & DOS, but linux still see it.

To turn off in kernel, use parameter: libata.force=1.00:disable

Like here with port SATA0, where HD is plugged...

Then nothing touch it. :)
But you know - it is virus - virus can possibly touch kernel and after reboot the virus can touch the HDD, am I right?

Anyway, I read if we turn off HDD in BIOS, the HDD still has electric power consumption. So I thing the best idea is mechanically cut HDD from electric power.

And then nothing touch it for sure finally.

I activated the Firefox module from desktop, and after reboot I must do it again, because the Firefox icon is gone after reboot. Should I put Firefox module to that "modules" directory? But I do not have access to that folder from desktop environment. But why I do not have access to my disc as guest? Is in my USB stick a block for guest?

So I see. And you are welcome. Trust me we were all newbies at one point. (Well, except for Bogomips. :D )

So you are saying the Firefox module is on your desktop!! Yes, you need to put it in your /porteus/modules/ folder.
But I do not have access to that folder from desktop environment.
Yes, so you will have to cp it in root mode. And once you reboot and have access to Firefox without activating it from the desktop you can delete the desktop module.
But why I do not have access to my disc as guest? Is in my USB stick a block for guest?
I can't answer that, I don't know. I've never formatted a drive with Linux Mint. We can look at it after we get the module in the right location.

@movobojo:
guest or normal user does not have access to folders or partitions that are root access only.

It could also happen that your home folder on hdd or other folders on your hdd could be encrypted if you have set them this way.

To access your hard disk drive (hdd) try:

Code: Select all

guest@porteus:/root$ su
Password: 
root@porteus:~# thunar
root@porteus:~#
And try to access your files.

Midnight commander could also be useful:

Code: Select all

guest@porteus:/root$ su
Password: 
root@porteus:~# mc
root@porteus:~#

Of course not.....sdc is a drive, not a partition --> sdc1 or whatever

OR as i said before

Code: Select all

guest@porteus:~$ ls $PORTDIR/modules

@ Ed

OK..
One can create such kind of devices if you dd an iso onto a thumb drive, for example,
(who does this?..and for what reason?), it would be read only then.
e.g.

Code: Select all

guest@porteus:~$ cat /proc/mounts
/dev/sdb /mnt/sdb iso9660 ro,noatime,nodiratime 0 0
which would result in

Code: Select all

guest@porteus:~$ cd /mnt
guest@porteus:/mnt$ ls
live/  sda1/  sda2/  sda3/  sdb/
guest@porteus:/mnt$ cd sdb
guest@porteus:/mnt/sdb$ ls
USB_INSTALLATION.txt  boot/  porteus/
guest@porteus:/mnt/sdb$ cd porteus
guest@porteus:/mnt/sdb/porteus$ ls
base/  make_iso.sh*  modules/  optional/  porteus-v3.2-i586.sgn  rootcopy/
guest@porteus:/mnt/sdb/porteus$ cd modules
guest@porteus:/mnt/sdb/porteus/modules$ ls
guest@porteus:/mnt/sdb/porteus/modules$

Here you are:

/mnt/sdb/porteus
guest@porteus:~$ 
So is it interesting?

Very much so!! It appears that we're talking about two different drives! What you are looking for and what you are running on are not the same drive. Also interesting to note that there is no partition number after sdb either.

I think we should wait for donald's input.
