very slow rescue WD5000LPVX

[fraltaro]

Hi all and thank you in advance for your suggestions and aid.

Some months ago my laptop dropped down on the floor when it is running. It doesn't starts anymore, so I open it and extract the HD (WD5000LPVX).
I used various tool in order to attempt rescuing some data. The most effective I found is gnu ddrescue.

DDrescue can copy the raw data, but the speed is very slow. The rate is between 27000 B/s and 45000 B/s. It takes 5-6 months for rescue the whole disk (500 GB).

I tried to change many ddrescue parameters and I tried to change hdparm flag and settings in the hope of increase the rate.
The rate remaining substantially the same. So I suppose that the problem is some aligning issue caused by the drop.

Someone can suggest some software, procedure or tips?

Thank you very much.

Send it to a professional data recovery lab that who will be able to safely diagnose and correct the point of failure.

if you kept using software on such hdd case (particulary dropped drives ) , i doubt that you will ever see your data again unless u r willing to pay extra $$$ is best scenarios ..

i am working on a similar case , where case was recoverable , and thanks to softwares and the owner faith in getting his data for free , now the case is unrecoverable ..

Thank you very much for yours advices.
HD content isn't very important data so I'm not interested in a professional rescue service.
Indeed I'm very curious about this field and I want try to rescue data as much as possible.

Until now I've rescued about 30Gb of not consecutive data.
I would like to try another strategy:
-reading the master file allocation table
-rescue only interesting file sector by sector

Is it possible? It is a feasible strategy.

Thank you for the support.

many tools do this:
r-studio
GetDataBack
dmde

but the more you read the drive the more damage it will do if there is any damage already in there ata all

[fraltaro]

Thank you very much HaQue!

I can see all files in the drive and I can rescue only needed files whit evaluation/demo version of dmde and r-studio (with some limitation).

It takes a while but I don't need to rescue the whole disk.

Are there some free tools similar to dmde and r-studio (preferably on Linux)?


Thank you again

Here is a Windows tool for recovering files with bad blocks.

If Linux OS is the point, then try UFS Explorer, three of its editions are available for Linux: http://www.ufsexplorer.com/download.php?prod=sr&os=lin

You can also fully test it in shareware mode and personal license e.g. for Standard Recovery is 40 Eur.
