I have a Samsung N135 notebook which boots well from USB. When I travel, I am afraid to damage the disk due to shocks. When I boot from USB and dismounts the build-in disk are the heads parked away from the platters? Is the disk not spinning at all? Is there a command to force power off of the disk!

Is it normal for mkisofs to use only 5% cpu power? it seems to take an awful long time to create a .iso file. Is there a way to force it to use more?
View 4 Replies View RelatedThe following script should make screen blanking work without disabling gnome-power-manager code...
This script can also be called from a panel launcher (with ./<scriptname> if it is in $HOME). It will not disable the power manager even though the process disappears from the system monitor. The "if" condition is necessary because SIGHUP will return an error if the process doesn't exist.
If you want a bash command, add this to $HOME/.bashrc:
# The following cannot be implemented as an alias
# and it cannot be called from a launcher, more's the pity

Since updating to C5.7 (64bit) when I go to burn an ISO it is not recognizing the blank disk and I have to use the force option(k3b). In 5.6 it worked fine. This is the same box of disks(and everything else) I was using before the update. The disks seem to burn fine (verify ok). It is just a PITA to have to hit the force button every time.

View 1 Replies View RelatedWhile using my computer the other day (I was sending an email) it suddenly turned off. I didn't get any low power warning, but I was running on battery and had my iphone charging from a USB port.
As I didn't think there was low battery, I just turned it back on again. As it was booting I saw the battery light flashing, indicating low power. I went to get the charger, but before I got it, mid boot-up it turned off again.
This seemingly damaged something hard-disk-wise.
Upon turning it on again it dropped into busy box with some message similar to this:
Quote:
No init fount. Try passing init= bootarg.
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu7) built in shell (ash) Enter 'help' for a list of build in commands
(initramfs)
That's not the actual message (copy pasted from another post) but the message is VERY similar to that.
If I "exit" busy box, I get a load of message about "kernel panic" before it freezes up.
I have booted a live USB (what I am using now). I thought since it wasn't cleanly unmounted, simply mounting and unmounting would do the trick. I was wrong.
Code:
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code].....
I had previously ran e2fsck (after checking it was unmounted) but it wouldn't run also because it was reporting that the device was already mounted, busy, or being exclusively used by a process.
I don't want to do any more for fear of causing further damage.
I am astounded that such damage can be caused so easily!
I am writing a shell script that unzips a ZIP file into an existing hierarchy of files, potentially overwriting some of the files. The problem is that the unzip command asks for confirmation: replace jsp/extension/add-aspect.jsp? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
This is unacceptable for a script.I need an option to force unzip to overwrite the files.I did not find in the man page nor with Google.

here is the problem I am facing. My system [ fedora 11 with all updates installed as of nov 27] suffered a power interuption.[ well that happens I dont have an UPS] here is what happen then
1- when i restarted i get stuck with the "install problem with gnome power manager" that prevent the desktop to launch. I found this to be well documented and I ssh'd [ for some reason cannot get the consol] my system and tried as root to remove gnome-power manager with yum remove power manager ... well the command hang out doing nothing and I have to close the session and reconnect... CTRL C dont even work.
So I had another problem. I started checking my system and when I tried df, I received the shocking following answer
[Code]....
My system does not power off completely after I trigger the "suspend to disk" function. The monitor gets blank and the usb-mouse does not light anymore, but the power led is still on and the pc fans can be heared. Interestingly, neither pressing the power button nor the reset button starts the pc in this state. I have to unplug the electrical power and then press the power button. After that, the system resumes nicely from the hibernation state as it should. I know that the hardware itself is capable of powering off because it worked perfectly before with opensuse 10.2, and I didn't change any bios settings either. I tried the option acpi=force, but to no avail.
View 2 Replies View RelatedI run Ubuntu Netbook 10.04 on my EeePC 1005HA. I'm going to get a SSD for it eventually, but I can't afford one right now so it's running from a 200GB hard disk I scavenged off a dead laptop.
I went in power management and set the option that says "spin down hard drives whenever possible", but this accomplished a whole lot of nothing - whenever the computer is on, the drive's spinning. I ran hdparm -y and the drive clicked off, and then promptly spun back up after a few seconds. Iotop shows occasional tiny bursts of activity from "jdb2/sda1-8", which I don't really know how to interpret, but I don't have anything weird installed so I'm assuming this is normal system operation.
Now, what I need is some sort of application, utility, command - anything - that forces the computer to keep all filesystem changes in RAM with the drive shut down; every five/ten minutes or so (this would hopefully be configurable) it spins up the drive, dumps the filesystem changes to it, and spins it down again.
I realize this presents data loss risks related to crashing and poweroffs when the cache hasn't been dumped to disk, but I'm willing to risk it as Linux never really crashes at all, and since it's a netbook power failures won't cause unexpected shutdowns.
Im trying to find out if my computer is whats got my power bill so high. Im not sure it is, but Id like to know if there is a shell command to monitor my power use.

View 3 Replies View RelatedIs there any way to allow normal fsck boot-time checks when running on battery power? After looking around, the only solution I've seen is to manually alter the /etc/init.d/checkfs.sh and /etc/init.d/checkroot.sh files and remove the AC power check. There must be a better way than that surely?

My laptop has a dead battery. Even when it's fully charged, if the power cable is pulled out it only lasts for about 4 minutes before it dies. I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.

I'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system.
