ddrescue

Command for ddrescue

using rescuecd
----------------------
ddrescue -b 4096 /dev/sda1 /mnt/windows

using ubuntu live cd
---------------------------
sudo -i
start update manage and enable univise
apt-get install gddrescue

ddrescue --no-split /dev/sda /dev/sdb --force

--force * sometimes will be needed to force it to write on the target drive. Use with care. It will erase all data on the target harddisk.

*** Remarks

/dev/sda is the source & bad drive
/dev/sdb is the new & empty drive

*** Some examples procedures

First you copy as much data as possible, without retrying or splitting sectors:

• ddrescue --no-split /dev/hda1 imagefile logfile 

Now let it retry previous errors 3 times, using uncached reads:

• ddrescue --direct --max-retries=3 /dev/hda1 imagefile logfile 

If that fails you can try again but retrimmed, so it tries to reread full sectors:

ddrescue --direct --retrim --max-retries=3 /dev/hda1 imagefile logfile

Win7 can't access NAS(Linux Samba Share)

For Win7 Pro & Ultima, Vista


1. Open the Run command and type "secpol.msc".

2. Press "continue" when prompted by Vista.

3. Click on "Local Policies" --> "Security Options"

4. Navigate to the policy "Network Security: LAN Manager authentication level" and open it.

5. By default Windows Vista sets the policy to "NTVLM2 responses only". Change this to "LM and NTLM – use NTLMV2 session security if negotiated".

Once you’ve done this Windows Vista will be able to view network drives based on Samba servers and should fix any issues around using Samba as a Primary Domain Controller.


For Win7 Home Pre(Not yet tested)

In Registry add DWORD LmCompatibility and set it from 0 to 2

Linux DD Disk Copy, Clone, Backup to image file

Hard Disk Clone

The following command can copy all the content from /dev/sda to /dev/sdb:

dd if=/dev/sda of=/dev/sdb

The following command will create an image file "disk1.img" in your user's directory from /dev/sda:

dd if=/dev/sda of=~/disk1.img

Since you have created an image file, you can compress it with "gzip" or "bzip2":

gzip disk1.img #generates disk1.img.gz or

bzip2 disk1.img #generates disk1.img.bz2

You can save much storage space with compression. But it will take very long time.

Partition Clone

For example, if you want to create an image file from the first partition of /dev/sda, use "dd" like this:

dd if=/dev/sda1 of=~/disk2.img

Also, you can compress the image file:

gzip disk2.img

You can copy a partition to another partition completely. For example:

dd if=/dev/sda1 of=/dev/sdb5


Restoring from an Image File

Restore the whole hard disk from the image file "disk1.img":

dd if=disk1.img of=/dev/sda

Restore the first partition of /dev/sda from the image file "disk2.img":

dd if=disk2.img of=/dev/sda1
