How to create SD Card DATA dump image to .ISO with dd and mount it with imdisk from command line on Windows CygWin with MobaXterm

Saturday, September 18th, 2021

dd-command-logo
I'm forced to use Windows every now and then and do some ordinary things which I do usually on Linux such as dumping the content of my Android phone SD Card SanDisk, Kingston etc. to .ISO image etc.

On Linux creating and mounting a data copy of a whole SD Card is a relatively simple thing and there are plenty of ways to do it such as using the dd ( command-line utility for Unix and Unix-like operating systems whose primary purpose is to convert and copy files as said in the command manual .- e.g. ''man dd'. ). On Microsoft Windows environment perhaps one of easiest ways is to use WinCDEmu (which is relatively free under LGPL License).
WinCDEmu is capable of doing plenty of things such as:
 

  • One-click mounting of ISO, CUE, NRG, MDS/MDF, CCD, IMG images.

  • Supports unlimited amount of virtual drives.

  • Runs on 32-bit and 64-bit Windows versions from XP to Windows 10.

  • Allows creating ISO images through a context menu in Explorer.

  • Small installer size – less than 2MB!

  • Have a portable version

WinCDEmu is a nice piece of software that perhaps every Win poweruser can enjoy, plus it has a nice Graphical frontend:

wincdemu-graphical-create-iso-and-mount-so-ms-windows-software

But what if you're a console geek, like me and you end up forced to be using Windows on your Work PC and you still need to create .iso dump of your Mobile SD Card or external attached Hard Drive, without the graphical mambo jumbo in the old fashioned way with dd?

Luckily Windows advanced command lined users could massively benefit from Cygwin + Mobaxterm (if you don't know or used MobaXterm and you still use things like Putty / SuperPutty or SecureCRT – perhaps you can reconsider and make your sysadmin life easier with MobaXerm gnome-terminal like SSH tabbed Windows alternative.

Once having mobaxterm + cygwin you have dd installed on the Windows host as it is part of the busybox minimal environment and you can use it in the same manner as your used in Linux environment.

1. Using dd to copy files on Linux / UNIX OS with a dialog status bar

To use dd the usual syntax on Linux / BSD / Unix is:
 

dd if=/dev/dev-name_ID of=/path/to/directory/dump/location.iso bs=2048

 

As 2048 BS (Bytes) per second is quite a low value usually on Modern operating systems, this bytesize is usually increased to some MBs  ( Megabytes).

For example if the reading from carrier  is Solid State Drive Disk (SSD) supporting 100 MBs per second and the output SD Card is a 32 Bit Kingston Plus+ drive with whose write speed is up to 50 ~ 100 MBs, you can use cmd as:

dd if=/dev/dev-name_ID of=/path/to/directory/dump/location.iso bs=100M


If you need to have a progress on the dd copy (in case if you copy some large SD Card 128 GB or 256GB or a full copy of a hard drive partition that is really big lets say 8 Terabytes of data, dialog and pv comes quite handy.

To use them install them first:

# apt-get install –yes pv dialog


Next to have a beautiful ncurses dialog box with the status (very useful if you're shell scripting), use:
 

(pv -n /dev/sda | dd of=/dev/sdb bs=128M conv=notrunc,noerror) 2>&1 | dialog –gauge "Running dd command (cloning), please wait…" 10 70 0

2. Listing the avaialble copy drives /dev/sda /dev/sdb1 … etc. disk locations on Windows 7 / 10 / 11 OS

[User.T420-89] ➤ for F in /dev/s* ; do echo "$F    $(cygpath -w $F)" ; done

check-drives-loop-on-cygwin-to-be-used-later-with-dd-copy-iso-creating-imageCheck drives device naming on WIndows PC – Screenshot extract from Mobaxterm

As you can see the drive location we've seen in Windows Explorer is located at drive E: above bash for loop reveals us this is located and readable from CygWin / MobaxTerm at /dev/sdb1


3. Create .iso image file on WIndows OS with dd command
 

To create a full data copy dump of to .iso (image file) with dd on Windows , I had to run:

[User.T420-89] ➤ dd if=/dev/sdb1 of=sdcard-blu-r1-hd-sdcard-backup_10092021a.img bs=100M

75+1 records in
75+1 records out
7944011776 bytes (7.4GB) copied, 391.794316 seconds, 19.3MB/s

4. Mount the newly create dd Image with imdisk

In order to test the image is properly created, you can attempt to mount it from command line on Linux, mounting it is quite easy and is up to mounting the just created .img file as a loopback (loop) device, like so: 

# mount -o loop file.iso /mnt/dir

Unfortunately cygwin and mobaxterm's embedded mount command on Win OS does not support the loopback device so to have it you have to install and use some additional program  such as the upmentioned WinCDEmu or if you prefer to do it fully from command line and further on automate the process of creating a dump of images of attached drives out of a multiple computers (lets say belonging to a Windows Active Directory domain). You might install and use something like:


imdisk 

imdisk-gui-interface-ms-windows-screenshot

imdisk handy tool is  created by Olof Lagerkvist. It is free and open-source software, which  will let you mount image files of hard drive, cd-rom or floppy, and create one or several ramdisks with various parameters either from a command line or via its Graphical interface.

To use imdisk download it from its home page on sourceforge extract and install it, pretty much as any other software it has both 32 bit version as a legacy for old computers as well as 64 bit exe installer.
The general command line use of it follows a cmd syntax like:

  • Mounting .iso image files from command line on WIndows host with imdisk


[User.T420-89] ➤ ImDisk.exe -a -f "sdcard-blu-r1-hd-sdcard-backup_10092021.img" -m #:

Where:
 

  • #: – is the actual drive you would like to mount to.
     
  • -a option stands for attach to, it will configure and attach a virtual disk with the parameters specified and attach it to the system.
     
  • -f – is self explanatory, provides the iso image file naming 

If you want to attach the newly created image to lets say  L:\ windows new mapped drive

ImDisk.exe -a -f "sdcard-blu-r1-hd-sdcard-backup_10092021.img" -m l:

  • Unmount mounted .img image with imdisk from cmd line

[User.T420-89] ➤ imdisk.exe -l
\Device\ImDisk0
                                                                                                                              ✘

[User.T420-89] ➤ imdisk.exe -D -m l:
Notifying applications…
Flushing file buffers…
Locking volume…
Failed, forcing dismount…
Removing device…
Removing mountpoint…
Done.

What we learned ?

What we have learned in this article is how to use Mobaxterm embedded dd Data Convert and Copy command to prepare full image backups of SD card or external drives on Windows OS. Also few alternative ways were entions such as using WinCDEmu free  open source alternative to DaemonTools program to create / mount or convert the image for the GUI lovers. Also for hard core sysadmins as me was shown how to list drives devices attached to the Win PC {/dev/sda,/dev/sdb} etc. and how to copy partition data with dd just like one would do on Linux OS. Finally to test the created image, I've shown you how to use the imdisk free software tool to attach and detach image to a mapped local Windows drive.

Hope this article learned you something new.

Saving multiple passwords in Linux with Revelation and Keepass2 – Keeping track of multiple passwords

Thursday, October 17th, 2013

System Administrators who use MS Windows to access multiple hosts in big companies like HP or IBM certainly use some kind of multiple password manager like PasswordSafe.

Keep multiple passwords safe in Microsoft Windows 7 passwordsafe with masterpassword

When number of passwords you have to keep in mind grows significantly using something like PasswordSafe becomes mandatory. Same is valid also for valid for system administrators who use GNU / Linux as a Desktop environment to administer thousands or hundreds of servers. I'm one of those admins who for years use Linux and until recently I kept logging all my passwords in separate directory full with text files created with vim (text editor). As the number of passwords and accesses to servers and web interfaces grow up dramatically as well as my requirement for security raised up I wanted to have my passwords secured being kept encrypted on my hard drive. For those who never use PasswordSafe the idea of program is to store all passwords you have in encrypted database which can be only opened through PasswordSafe by providing a master password.

passwordsafe on microsoft windows keep in order multiple passwords manager

Of course having one master password imposes other security risks as someone who knows the MasterPass can easily access all your passwords anyways for now such level of security perfectly fits my needs.

PasswordSafe is since recently Open Source so there is a Linux port, but the port is still in beta and though I tried hard to install it using provided .deb binaries as well as compile from source, I finally give it up. And decided to review what kind of password managers are available in Debian Wheezy's ports.

Here are those I found with;

apt-cache search password|grep -i manager

cpm – Curses based password manager using PGP-encryption
fpm2 – password manager with GTK+ 2.x GUI
gringotts – secure password and data storage manager
kedpm – KED Password Manager
kedpm-gtk – KED Password Manager
keepass2 – Password manager
keepassx – Cross Platform Password Manager
kwalletmanager – secure password wallet manager
password-gorilla – cross-platform password manager
revelation – GNOME2 Password manager

I didn't have the time to test each one of them, so I installed and checked only those which seemed more reliable, i.e.:
keepass2 and revelation

# apt-get install –yes fpm2 keepass2 revelation

Below is screenshot of each one of managers:

Revelation Linux Gnome graphic password manager program

Revelation – GNOME Password Manager

keepass2 Linux gui password manager screenshot Debian - graphic manager for storing passwords

kde password safe gui program Linux Debian screenshot

KDE QT Interface Linux GUI Password Manager (KeePass2)

With one of this tools admin's life is much easier as you don't have to get crazy and remember thousands of passwords.
Hope this helps some admin out there! Enjoy ! 🙂
 

Ubuntu 9.04 Jaunty on Toshiba L300 PLSBGE Laptop

Sunday, September 20th, 2009

toshiba-l300-plsbge-laptop-ubuntu-9.04-install

Today I had the task to Install Ubuntu GNU / Linux on Toshiba L300 PLSBGE Laptop.

I had already installed Windows Vista Enterprise on the notebook. Thus I used Acronis Disk Directory Suite to partition the harddrive for Ubuntu even though I could have used the gparted included on Ubuntu’s installation CD. I’ve asked specificly if
I could use the Ubuntu CD to repartition my hard drive in #ubuntu in irc.freenode.net.
The answer was positive it’s absolutely safe to resize an NTFS partition using Ubuntu’s installation LiveCD and gparted.That seems like a good news for all of us the free software users / enthusiasts / hobbyists etc.
I hated the default Ubuntu behaviour it automatically decided to install itself on a automatically created 2.5 GB partition.
I thought it won’t be so dumb to install itself on such a tiny partition. Well guess what I was wrong IT WAS SO DUMB!
Even though I had already 80 GB ext3 partition. Ubuntu’s default behaviour was to install on an automatically created 2.5GB partition.
Right after the installation I was stunned just to realize there was no free space on the drive where the dumbass installed itself.
After that I had some issues deleting the already cretead partitions, which for some reason messed up. Luckily the good old fdisk fixed the situation so I could easily delete all the partitions except the vista and recreate them again using gparted with Ubuntu’s install LiveCD. The install was completely flawless. Everything worked out of the box, no external efforts to fix broken stuff like usually happens in Linux fantastic! The only broken thing was that switching to plain console with ctrl+alt+f1 would visualize a non working display output and I couldn’t see the ttys at all. That wasn’t such a hassle since the system is planned to work only in GUI mode. I guess Ubuntu is going through a real development with a positive end results. Even external USB printer Canon PIXMA IP3300 worked by simply plugging it in. For some weird reason to make the printer work correctly I had to use driver for Canon PIXMA IP3000. Anyways it worked with it and the printer started printing correctly even though officially on some of the linux printers databases it’s reported the printer won’t work correctly never ever.END—–

How to fully recover deleted files on ext3 Debian Linux partition – undelete files from ext3 filesystems with ext3grep

Monday, March 7th, 2011

In order to recover fully data by mistake or on purpose deleted on Debian GNU/Linux there is a tool called ext3grep which is able to completely recover data by innodes.

Recovering the deleted files data is very easy and can be done via some livecd after installing the ext3grep tool.

In my case I used the Back Track Linux distribution to recover my data. Recovery is still in process and it appears all or at least most of my data is about to be recovered.

For the recovery procedure all necessary is an external partition in ext3 or ext3 where the recovered data from the ext3 device can be stored.

My partition was about 20GB and since I had no external hard dive to store the data to I used the sshfs to mount remotely a hard drive via the networking using the sshfs program to make the ssh mount for more see my previous post Howto mount remote server ssh filesystem using sshfs

The Backtrack livecd linux security distribution is missing the ext3grep tool thus I had to first install the tool after booting the livecd on the notebook to succeed in that it was necessary to install the e2fslibs-dev package through the command:

debian:~# apt-get install e2fslibs-dev

Further on I've downloaded the latest version of the ext3grep and untarred the archive and compiled it with the commands:

debian:~# ./configure && make && make install
Then I used the simple commands:

debian:~# cd /mnt/res
debian:~# ext3grep --restore-all /dev/sda8

to launch the recovery.
Where in the above commands /mnt/res is the mountpoint location where I wanted to have all my data recovered and the /dev/sda8 is the device from which I wanted to recover my data.

It takes a bit long until the recovery is completed and with 20 gigabytes of data about 5, 6 hours might be necessary for the data to be recovered but the main point is it recovers.

Checking I/O Hard Disk (Overhead) Read / Write operations on Microsoft Windows 7 – Resource Monitor

Friday, July 26th, 2013

I mainly have to deal with Linux servers. Today however I had to check for problems Microsoft Windows 7 server. The machine looked Okay but was reading from hard drive all the time. Hence I needed to check what is the Hard disk approximate read / write speed per second. I know on lInux tracking i/o hard disk server bottlenecks is done with iostat or dstat.

However I never did that on Windows, so I had to learn it by experience. Its actually pretty easy and you don't even need to install external program to see read / write hdd speed operations. Windows 7 is bundled with a Program called Resource Manager. Running Resource Manager's easiest method is from Windows Task Manager, i.e.:

Windows 7 Task Manager processes performance tab - how to check hard drive bottleneck windows server
Press Ctrl + Alt + Del (Choose Start Task Manager) and from Task Manager click on Resource Monitor Button.
Immediately resource Monitor pops up and selecting the Disk tab priovides information on HDD Read / Write speed per sec. Using Resource Monitor, you can quickly also see which process is creating the most HDD overhead for server.

windows resource monitor disk tab hard disk show read write speed win7

Though I'm not Microsoft fan, I should admit Resource Manager does a great job.

 

Save data from failing hard disk on Linux – Rescuing data from failing disk with bad blocks

Wednesday, April 16th, 2014

save-data-from-failing-hard-drive-data-recovery-badblocks-linux_1.jpg
Sooner or later your Linux Desktop or Linux server hard drive will start breaking up, whether you have a hardware or software RAID 1, 6 or 10 you can  and good hard disk health monitoring software you can react on time but sometimes as admins we have to take care of old servers which either have RAID 0 or missing RAID configuration and or disk firmware is unable to recognize failing blocks on time and remap them. Thus it is quite useful to have techniques to save data from failing hard disk drives with physical badblocks.

With ddrescue tool there is still hope for your Linux data though disk is full of unrecoverable I/O errors.

apt-cache show ddrescue
 

apt-cache show ddrescue|grep -i description -A 12

Description: copy data from one file or block device to another
 dd_rescue is a tool to help you to save data from crashed
 partition. Like dd, dd_rescue does copy data from one file or
 block device to another. But dd_rescue does not abort on errors
 on the input file (unless you specify a maximum error number).
 It uses two block sizes, a large (soft) block size and a small
 (hard) block size. In case of errors, the size falls back to the
 small one and is promoted again after a while without errors.
 If the copying process is interrupted by the user it is possible
 to continue at any position later. It also does not truncate
 the output file (unless asked to). It allows you to start from
 the end of a file and move backwards as well. dd_rescue does
 not provide character conversions.

 

To use ddrescue for saving data first thing is to shutdown the Linux host boot the system with a Rescue LiveCD like SystemRescueCD – (Linux system rescue disk), Knoppix (Most famous bootable LiveCD / LiveDVD), Ubuntu Rescue Remix or BackTrack LiveCD – (A security centered "hackers" distro which can be used also for forensics and data recovery), then mount the failing disk (I assume disk is still mountable :). Note that it is very important to mount the disk as read only, because any write operation on hard drive increases chance that it completely becomes unusable before saving your data!

To make backup of your whole hard disk data to secondary mounted disk into /mnt/second_disk

# mkdir /mnt/second_disk/rescue
# mount /dev/sda2 /mnt/second_disk/rescue
# dd_rescue -d -r 10 /dev/sda1 /mnt/second_disk/rescue/backup.img
# mount -o loop /mnt/second_disk/rescue/backup.img

In above example change /dev/sda2 to whatever your hard drive device is named.

Whether you have already an identical secondary drive attached to the Linux host and you would like to copy whole failing Linux partition (/dev/sda) to the identical drive (/dev/sdb) issue:

ddrescue -d -f -r3 /dev/sda /dev/sdb /media/PNY_usb/rescue.logfile

If you got just a few unreadable files and you would like to recover only them then run ddrescue just on the damaged files:

ddrescue -d –R -r 100 /damaged/disk/some_dir/damaged_file /mnt/secondary_disk/some_dir/recoveredfile

-d instructs to use direct I/O
-R retrims the error area on each retry
-r 100 sets the retry limit to 100 (tries to read data 100 times before resign)

Of course this is not always working as on some HDDs recovery is impossible due to hard physical damages, if above command can't recover a file in 10 attempts it is very likely that it never succeeds …

A small note to make here is that there is another tool dd_rescue (make sure you don't confuse them) – which is also for recovery but GNU ddrescue performs better with recovery.
How ddrescue works is it keeps track of the bad sectors, and go back and try to do a slow read of that data in order to read them.
By the way BSD users would happy to know there is ddrescue port already, so data recovery on BSDs *NIX filesystems if you're a Windows user you can use ddrescue to recover data too via Cygwin.
Of course final data recovery is also very much into God's hands so before launching ddrescue, don't forget to say a prayer 🙂

Archive Outlook mail in Outlook 2010 to free space in your mailbox

Thursday, May 15th, 2014

outlook-archive-old-mail-to-prevent-out-of-space-problems-outlook-logo
If you're working in a middle or big sized IT company or corporation like IBM or HP, you're already sucked into the Outlook "mail whirlwind of corporate world" and daily flooded with tons of corporate spam emails with fuzzy business random terms like taken from Corporate Bullshit Generator

Many corporations, because probably of historic reasons still provide employees with small sized mailboxes half a gigabyte, a gigabyte or even in those with bigger user Mailboxes like in Hewlett Packard, this is usually no more than 2 Gigabytes.

This creates a lot of issues in the long term because usually mail communication in Inbox, Sent Items, Drafts Conversation History, Junk Email and Outbox grows up quickly and for a year or a year and a half, available Mail space fills up and you stop receiving email communication from customers. This is usually not too big problem if your Mailbox gets filled when you're in the Office (in office hours). However it is quite unpleasent and makes very bad impression to customers when you're in a few weeks Summar Holiday with no access to your mailbox and your Mailbox free space  depletes, then you don't get any mail from the customer and all the time the customer starts receiving emails disrupting your personal or company image with bouncing messages saying the "INBOX" is full.

To prevent this worst case scenario it is always a good idea to archive old mail communication (Items) to free up space in Outlook 2010 mailbox.
Old Outlook Archived mail is (Saved) exported in .PST outlook data file format. Later exported Mail Content and Contacts could be easily (attached) from those .pst file to Outlook Express, leaving you possibility to still have access to your old archived mail keeping the content on your hard drive instead on the Outlook Exchange Mailserver (freeing up space from your Inbox).

Here is how to archive your Outlook mail Calendar and contacts:

Archive-outlook-mail-in-microsoft-outlook-2010-free-space-in-your-mailbox

1. Click on the "File" tab on the top horizontal bar.Select "Cleanup Tools" from the options.

2. Click "Cleanup Tools" from the options.

3. Click on the "Archive this folder and all subfolders" option.

4. Select what to archive (e.g. Inbox, Drafts, Sent Items, Calendar whatever …)

5. Choose archive items older than (this is quite self-explanatory)

6. Select the location of your archive file (make sure you palce the .PST file into directory you will not forget later)

That's all now you have old mails freed up from Outlook Exchange server. Now make sure you create regular backups ot old-archived-mail.pst file you just created, it is a very good idea to upload this folder to encrypted file system on USB stick or use something like TrueCrypt to encrypt the file and store it to external hard drive, if you already don't have a complete backup corporate solution backuping up all your Laptop content.

Later Attaching or detaching exported .PST file in Outlook is done from:

File -> Open -> Open Outlook Data File

outlook-open-backupped-pst-datafile-archive-importing-to-outlook-2010


Once .PST file is opened and attached in Left Inbox pane you will have the Archived old mail folder appear.

You can change Archived name (like I did to some meaningful name) like I've change it to Archives-2013 by right clicking on it (Data File properties -> Advanced)

How to disable GNOME popup notification in Debian Wheezy Linux

how to disable remove GNOME 2 / 3 popup e mail notification Debian Ubuntu Linux screenshot

I found it very annoying to have a pop-up notification every time I receive a new email it is just pointless there especially, when I already use Thunderbird (IceDove) to fetch my email via pop3. This pop-up notification though planned to be useful messes with my Desktop and breaks the habit on how I'm used to old GNOME interface…. I remember same popup notification was present on older Fedora releases (back in time when I used Fedora Linux for my Desktop).

disable Gnome popup notification new email Debian GNU Linux Wheezy 7 screenshot

My logical guess was in order to disable popup notification in GNOME 3 I had to tamper with gconf-editor. In gconf-editor config database there is:

Apps -> Notification daemon

Problem it is not possible to turn it off. Only available change options are:

default-sound, popup_location, sound_enabled, and theme

After some time of try / fail attempts I found the solution on linuxquestions forum, its quite raw solution but it works, all I had to do is change permissions of /usr/lib/notification-daemon/notification-daemon;

debian:~# chmod 0000 /usr/lib/notification-daemon/notification-daemon

Another thing that is handy to disable is POP UP Window with warning that you have low disk space on Hard Drive.

The warinng for Disk space is very annoying and popups up on every GNOME boot. Actually the hard drive with Low disk space is and old mounted partition in NTFS and I only use it to read data.

Here is how to disable HDD Notification Warnings in GNOME:

debian:~# chmod 0000 /usr/lib/gnome-disk-utility/gdu-notification-daemon

Teracopy faster Windows copy or Save files from Windows PC with dying hard drive

Wednesday, July 3rd, 2013

TeraCopy logo copy files faster and prevent windows hangs up on broken hard disks
My sysadmin colleague mentioned today about TeraCopy. An application for Microsoft Windows designed to be used to Move or Copy  files. So why would one want to use Teracopy instead of normal Windows Explorer copy integrated soft? Reason is Teracopy is faster than MS Windows Copy / Move and uses dynamically adjusted buffers to reduce seek times. This asynchronous copying speeds up file transfers between physical HDDs.

More precious feature of TeraCopy is whether you have to Save data from hard disks with Bad Sectors, it can skip faulty files (stored on bad sectors) without triggering Windows to hang up or halt with the Blue Screen of Death.TeraCopy even can be setup to replace Windows Explorer (i.e. Shell Integration copy and move functions). Beside that it works well with Unicode encoded file names (Cyrillic, Chineese) etc.

Teracopy copying files on Microsoft windows 7 substitutes default windows copy and move opeartions

As of time of writting article, TeraCopy has support for all Windows NT (Windows XP / 2000) as well as for Windows 7 and 8. Whether a failure to copy file occurs it tries to recopy file several times in order to achieve copy success. After each file is copied a CRC check up value of file is calculated and matched. It also provides a way more verbose information on copied files than Windows default Copy. It is very useful in copying large files from system to system as file transfers complete time is significantly lower

teracopy with more information on copying files screenshot MS Windows

Once TeraCopy is installed it automatically does replace Explorer Copy and Move functions, hence after install every next Move or Copy operation is auto handled by it. In preferences the user could still revert back Copy / Move functions to Explorer original.

TeraCopy copy faster files and save files from broken win hdd preferences screenshot

Unfortunately TeraCopy is not-free software but freeware and can only be used to non-commercial use, for commercial use you have to purchase TeraCopy Pro version.

Controlling fan with Thinkfan on Lenovo Thinkpad R61 on Debian GNU/Linux (adjusting proper fan cycling)

Saturday, August 7th, 2010

Some time ago before I have blogged about How to properly control your Lenovo Thinkpad R61 fan rotation cycles on Linux with ThinkFan
In this tiny article I have explained my previous obstacles of making my Notebook CPU cooling fan to properly rotate and cool up my Central Processing Unit.

However just recently I’ve upgraded my Debian Unstable – Squeeze/Sid through the apt-get manager to the newest possible package updates.
The upgraded bundle of packages also updated my sid thinkfan package to:

hipo@noah:~$ dpkg -l |grep -i thinkfan
ii thinkfan 0.7.1-1 simple and lightweight fan control program

I was unpleasently suprised when I tried to restart thinkfan using the thinkfan init.d script I have used until recently /etc/init.d/thinkfan , cause /etc/init.d/thinkfan was no longer be.

Furthermore I give a try to directly launch the thinkfan daemon from the terminal trying to backround the service, like so:

noah:~# thinkfan &
WARNING: Using default temperature inputs in /proc/acpi/ibm/thermal.
WARNING: You have not provided any correction values for any sensor, and your fan will only start at 55 °C. This can be dangerous for your hard drive.

Though this started up the thinkfan daemon as you can see the note in the message below it started up with a consistent cycling cooling to keep the CPU wamrth sticked to 55 ° degrees:
<</p>
