Imaging to File by jumping over sectors? Windows tools hang!

November 16th, 2015, 15:50

Hello everyone,

i partially rescued the data of the Hitachi HD -- for SMART data see attached image. The more I tried to get access to data the less it was successful.

I made a scan with MHDD and jumped to the next block? and then there were sectors were readable again...

is it possible to make an image with a tool that jumps sectors the way like MHDD does? Windows Tools keep hanging all the time... Who wonders? ;-)
Is it even possible after windows tools (R-Studio; dmde) keep hanging?

"Only" need the wedding images

Thanks in advance
Benjamin

Use ddrescue for Linux - windows not really ideal for full control.

have a look at a great guide provided by a forum member that seems to be able to pull 28 hours of work out of each day :)

Hi Benjamin,

you can also try DMDE it has nice features to jump & read back. As long as the drive is in a rather good condition it might work. But do not play with client's data ... :evil:

Best luck,

Hi. In your situation with a lack of tools I would approach the task like this.

I would switch off smart.
I would scan various areas in Mhdd or Victoria to get an idea where bad sectors are located.
Then I would start to clone the drive to an empty replacement.
When you start hitting lots of bad sectors I would stop. Also take a note of the current location.
Then I would start cloning in reverse direction.

You can choose do this in either Dmde or ddrescue.

If the data is really important then approach a pro who would image the drive for you on hardware based equipment.

Good luck!

Stop scanning the drive...it is not making things any better and is likely only making things worse.

This drive likely has at least one head that is crashing. If you are 100% sure that you will not ever consider a data recovery professional, even after you fail to recover your files, I suggest cloning with ddrescue.

Once you have the clone, with lots of missing sectors, you will likely need to run a full scan with a file system recovery program like R-Studio.

Hello guys,

thanks to you a lot for this detailed information. Thanks for your time and your expertise you offered me! I'll give it a try cloning it with ddrescue.

I already have important parts of the data. Cross your fingers.

Best Greetings from Germany
Benjamin

With a little bit of help :wink: ddrescue is imaging right now to a file... hopefully it will get faster!


edit: second image - this speed I want

Does the ratio of errors to rescued seem good to you?

Assuming one main partition, the OP is going to have a very broken MFT.

jermy, what does that mean?

Code:
ddrescue /dev/sda2 /media/sdb2/Image/partition.img /media/sdb2/Image/partition.log


omg.. due to an error I did I started it again and in this case only the partition I need. Some people told me to shut down smart or i in the case of jermy turn off autoreassign. what does that mean? Does ist make sense when the process is to slow?

Splidit thank you very much for your information. That helps me to be more confident and getting more a feeling for hardware assisted tools.. should buy one! "Mother, can you lend me some money for PC3000!?" ;-)
