Correction:
ddrescue dose not equal dd_rescue!!! The apt database is confusing in this regard.
“ddrescue” (gddrescue in apt) is a GNU app that is _far_ superior to dd_rescue (ddrescue in apt). Check synaptic. Check man page and info for GNU ddrescue at the linked site below. As I said it’s far superior to dd_rescue (faster, more sensible output).

Damn, i can’t get it to work!!

for clarity,
* the PACKAGE “gddrescue” provides the COMMAND ddrescue
* the PACKAGE “ddrescue” provides the COMMAND dd_rescue

GNU ddrescue is the first one, and seems IMHO better/more flexible than dd_rescue.

actually gddrescue is the one you want, its updated more frequently and incorporates the functions of the original dd_rescue and dd_rhelp.

you write: “dd_rescue (also known as ddrescue)”. they are not at all the same software.

ddrescue and dd_rescue are completely different programs which share no development between them. the two projects are not related in any way except that they both attempt to enhance the standard dd tool and coincidentally chose similar names for their new programs.

ddrescue is the one to get.

On my Ubuntu 7.10, I can install the tool ddrescue
sudo apt-get install ddrescue

And it got installed:

Actually, the command on Ubuntu should be
apt-get install gddrescue.

Not ddrescue. You have to have the g there.

The Linux tool called GNU ddrescue written by Antonio Diaz Diaz should not be confused with dd_rescue written by Kurt Garloff
They are two different utilities.

You guys might want to look at dd_rhelp also

I haven’t used it but it seems to shorten the amount of time dd_rescue takes.

Is there any other tool to recover files? I have a hard drive with bad sectors. It is an NTFS filesystem and has some importnat data on it. I have tried dd and now ddrescue, to no avail. I was trying to use autopsy/sleuthkit – but it requires an image. I am pulling my hair out trying to recover the files from this thing. I don’t care about the drive, just the data. All RAID from now on.

Does anyone have a link to a ddrescue man page that is something more than that the program itself puts on screen when the user enters parameters incorrectly? It would be nice to know more about ddrescue than just what the options list is!

I have on hd with NTFS file system which has important data to backed up and I have one more computer which has Readhat linux installed on it. How I can use dd_rescue to retrive data out from that hd having NTFS file system.

My personal experience is dd is slow and dd will never display any progress (which makes me more nervous about my data … LOL). I love ddrescue – one perfect tool for data recovery.

@htc,

Hmm…

Try to update apt database and again run same command:

apt-get update
apt-get install ddrescue

HTH.
