Data recovery

Postby trobbins » Tue Jun 16, 2009 10:54 pm

Have you ever had one of those days were you tried to copy a file and get that dreaded file corrupted, or file in use error?
No matter if the source is a floppy, hard drive, thumb drive, CD, or DVD, or even a network drive, this program will your butt.
Imagine your cat has puked on your only cd copy of your homework. So you didn't notice right aways and now
that puke has etched a film on the surface. What do you know, you can only access a few of those important files.

What you need is Roadkil's Unstoppable Copier.!

Head on over to roadkil[dot]org and get your free copy today.!

I haven't needed it yet myself, but I am sure it is a good tool to have in your toolbox.

Well... data recovery is a HUGE topic.
If you use some Linux/BSD OS you should have heard/used the "dd" command
http://en.wikipedia.org/wiki/Dd_(Unix)
If you are looking for some windows based, free tools to make a "perfect clone" of your damaged media/device then you can use

a) DrDD- DataRescue's DD (http://www.datarescue.com/photorescue/v3/drdd.htm) (no setup)
b) FTK Imager version 2.6.0 (you have to install it) (http://www.accessdata.com/downloads.html)
c) FTK Imager Lite version 2.5.4 (no setup needed) (http://www.accessdata.com/downloads.html)

with these tools you can make a "perfect, low level" copy and even perform data recovery on your clone and not at your damaged media/device.

Thanks for the tech tips, labmice.

I don't like to picture that, but this topic is very important, even with some humour added into this discussion.

This is good stuff. Keep it coming. Here is an idea. Those of us who fight spam are particularly vulnerable to malware attacks because sometimes we decide to take higher risks and also because the bad guys eventually figure out who we are and were to find us, no mater what steps we take to insure our anonymity. If we are running windows systems, we are particularly vulnerable. Therefore, file recovery or system recovery are potentially very important to us. It seems to me that we would all benefit from drawing on the collective knowledge of our community. File recovery and system recovery should be and probably is of prime importance to us. I think we should have a top-level thread for that. So, how about it? Maybe, those of you who have the necessary administrative privileges could do something about that. What do you say?

since we are on the topic of tools we haven't actually used...here's some research I did i 2007.

cloning utilties
http://www.partimage.org/ (copies only stored data from filesystem w/o mounting it)
current version of partimage does not allow you to restore to a smaller partition ( http://www.partimage.org/forums/viewtopic.php?t=489 )
also says "The NTFS (Windows NT File System) is currently not fully supported"
( http://www.partimage.org/Main_Page )

http://device-image.de/ (copies byte-for-byte, including empty areas of partitions)

http://www.feyrer.de/g4u/#badalternatives

http://drbl.sourceforge.net/ (server) + http://clonezilla.sourceforge.net/
(alternative to norton ghost enterprise?)

from the device-image.de faq
Q1. How does deviceimage compare to partitionImage project?

A: The main difference is the following:

partimage analyses and operates on the file-system level,
device-image instead, operates on the device level.

Therefore the advantage of partimage lies in the possibility to to read out the information only from used blocks making a very small image.

The disadvantage is if the file system structure (as in case of NTFS) is not completely known, the support of this file system remains permanent experimental.

Consequently you are not sure if your backup image is restorable.
The operation mode of device-image is copying byte-by-byte, it means all sectors, regardless of containing or not any data, will be stored in one image.
In this case the big advantage is independence from the file-system.
Because we save really all data, as additional positive effect here we have a following one:
if you want undelete some data which you deleted just before your last imaging it is also possible in contrast to partimage-method.

The disadvantage of device-image method is: for restoring you need a device which is the same or bigger in size than original one.

R-Studio is another great recovery tool. I do have a copy and used it to recover a 3 drive spanned windows partition when one drive went bad. Even works with unrecognizable raids.

http://www.data-recovery-software.net/#features

Plus it is fairly inexpensive at $49 - $79 depending on what features you really need. They do have other more expensive versions, but I don't think there is anyone here that would need those features.
