Re: [Bug-ddrescue] A live CD with GNU ddrescue and Parted to recover a partition

[andrew zajac]

Hi Jony.

Both GNU ddrescue and GNU parted are on Ubuntu-Rescue-Remix.

Including both those application in the default Live CD with graphical desktop would not help you since you would still have to run them from the command line.  The problem is that there is no graphical interface for them.

That being said, what exactly happened to the drive?  You say there is a lost partition.  If the partition is lost, there is no way to image it without imaging the entire drive.  If the missing partition is the only problem and it was removed from the partition table due to error rather than hardware failure, then it is pretty much safe to just try to repair the partition table on the disk.  Changing the partition table doesn't do anything to the actual data on the drive so the risk is minimal.

I would recommend Testdisk to recover the lost partition if this is just a simple case of something deleting the partition from the partition table.  Testdisk is easy to run the the command line.

Andrew Zajac

Hello,

I'm new on ddrescue and in Linux.
Is there a *live CD* of a Linux distro, that contains ddrescue and GNU Parted?

-------

My problem is to recover a harddisk, that lost the partition table, but must contain the data.
(The disk has installed a Windows XP).

I studied the guidelines of
https://help.ubuntu.com/community/DataRecovery

This plan looks the best:

1) I have to avoid mounting the damaged disc.
The best way is to use *a live CD*, open the Terminal and use the command sudo swapoff -a

2) First it is better to obtain *an image copy* of the damaged partition, which I can achieve with GNU ddrescue.

3) Using GNU Parted over the created image.

I went back to my Ubuntu 11.04, and found that both programs, ddrescue and GNU Parted are not included. So I cannot use it as a live CD for this.

I tried to check if I can use the UbuntuRepairRemix: but:
a) it offers only a terminal and is apparently too complicated and risky for a person that have just come from Windows.
b) I do not know how to see the names of the disks (for example, which is deb/sdb and whic deb/sdc), to perform the commands.
(I know this through to the Disk Utility -Utilidad de Discos- that is included in Ubuntu 11.)
c) It contains the GNU ddrescue, but not the GNU parted, although later I could run it installing it in my Ubuntu system.

---------
Therefore:
I wonder if someone knows about a liveCD, that contains these two programs, GNU ddrescue and GNU Parted (recommended in https://help.ubuntu.com/community/DataRecovery )
I suggest that it might be a good idea to include both within the next live CD of Ubuntu.

Alternatively, I guess that someone could tell me what to do.
Should I use NtfsUndelete in a live CD?
It looks it only recovers files, not particions.

Many, many thanks,

Jony :-)
