Hi,

My friends have an unexpected issue with his laptop and precisly with hishard disk.

I do several modification but i'm stuck with another problem i'm afraid i can't go through this time.

The goal is only to recover few data (a memoire in fact).

 

Here is his partition table :

 

(before error)

/dev/sda 1 RECOVERY 1.30 Go

/dev/sda 2 OS (windows 8) 372 Go

/dev/sda 5 DATA 537 Go

 

(after error)

/dev/sda 1 UNALLOCATED

 

This is what i get after few manipulation, partition recovery with tesdisk and other program (the hard disk have some hardware damage).

Plus i didn't recover sda 1 because it's isn't necessary for us :

/dev/sda 1 extended 372 Go

'-- > /dev/sda 5 (NTFS partition = OS probably) 372 Go

/dev/sda 2 DATA 537 Go

 

I need to access /dev/sda 5 again which is the OS partition (i could backup few data but after few manipulation for better access i blew up the HDD).

OS is no longueur accessible, and the fact of sda5 is IN sda1 block access to all tools.

sda 2 (DATA) is mountable when disk won't crash) but it's sda 5 (OS) who is important and locate his data.

How sda 1 and sda 5 have the same size and how could I make sda 5 the primal partition fot gain access ?

I give you the screenshot of the partition table.

 

Thanks for your help !

At this point I think the partition table has been corrupted and is no longer mountable. Your best bet is to do a hex dump if you know how to do it and try to recover the data individually... otherwise take this to a forensics expert and they can try but it wont be cheap...

If the data you need to recover is less than 2GB you can scan the drive with Easeus Data Recovery

 

You can also try PhotoRec, part of Testdisk. Make sure you select the whole disk and under folder options select the extensions of the files you are trying to recover because by default it will recover every file on the disk it finds. PhotoRec recovers files with a generic files names. You will have to open the file and give it an appropriate name.

Thanks for your reply guys.

 

@BenjaminGodrdonT : I see what you talk about but i don't know any tools who do that. Can you link me one of it please ?

 

@JohnC_21 : I already use Photorec (Hiren's boot toolbox) but i can no longer use it. The disk is instable, i could backup few datafiles but the second time i denied any access. That's the reason why i try further manipulation and came here with this situation. I'm gonna try EaseUS. I have no idea if it can help me in this case (hope so).

 Some folks use Recuva for situations like yours.  I've never had need for it because I always make full system backups regularly.

 

 Good luck.


Make regular full system backups or you'll be sorry sooner or later.

Recuva could not be efficient as the disk isn't accessible. There is a partition plus physical damage on it.

I need to modify the disk to get a new access and backup file who are not damaged or corrumpted, only blocked by a partition issue.

And, if/when you do recover the file onto another media, test it by trying to access it.  Not every recovered file works like before.

Do you talk about CD Live and theses kind of media ? Yes i did.

The problem to access it seems to be on the partition table : The extended is not reconise but it cover the OS partition in it.

How can i make the selected one like /dev/sda2 ?

 As I understand it, Recuva works even if you have formatted the drive.  It goes through sector by sector piecing files together.  I've never used it, but I've seen a lot of positive comments about it in other forums (e.g. CNET).

 

 Good luck
