Here is the context:

- I wanted to save the data of a 2 TB HDD plugged into a Dlink DNS-320L NAS.

This NAS was connected to my old PC (With a Win XP OS)

I have not used this HDD since about 6 months but I noticed I could not access it.

So now that I have a new PC (with a Win 10 OS) I wantto save the data but I have problems ...

Here is what I made:

1/ on Win 10:

-  I successed in connecting the Dlink DNS-320L NAS and the led of HDD was green so the HDD is considered as ok

but I only see a part of a little partition of the HDD (about 150gb of 2 To)

I tried to use a lot of utilties ext2f ... but without sucess

I also tried to directly connect the HDD in Sata but without success

2/ I decided to reconnect the HDD with my old PC directly in Sata (WinXP) and used
https://www.diskinternals.com/linux-reader/

with this utility I could have access to a 550 Gb partition of the HDD but not to the main partition (around 1,20 To)


for information the HDD makes a normal noise and the different utilities and the disk mamangement of windows don't etect a problem with it.

I just noticed that the 2TB HDD was detected as a RAW filesystem.
Is it normal that his filesystem is RAW ? it should be ext 3 normally ?
Perhaps I should try other utilities but which one ? (on Win XP or Win 10 it doesn't matter)

Thanks for your help.

Raph

Windows would see the disk as RAW because to it there is no partition table. The drive was formatted with a linux file system, correct? See this thread for possible solutions. The Linux version of R Studio using linux seemed to give the best chance of recovery.

 

Running Testdisk in Windows on the drive may allow you to recover the data. 

 

https://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

 

I would not attempt to write a new partition table. You can recover your data if you can detect your partitions using the Quick Search or Deeper Search. Press the "P" key to see your files on the detected partition(s). You can copy the files back to the unzipped folder of Testdisk. You can't use the "'a" key to select all files if your free space on the recovery drive is not larger than the data you are recovering. Use the ":" key to select files and directories.

Ok thanks. I will try at first with Test Disk and will indicate if it solved the problem.

 

I will try other solutions if it fails.

I tried with Testdisk on Windows but without resultat (no valid file when I click on "P" key. I'll try other software to see if I have best results.

JohnC, I must have forgotten, is this Linux R-Studio a USB or DVD boot?  I have R-Studio Network (the $179 package).  Many pages, including R-Studio, are blocked by my school firewall/ISD IT  :)

Yep, I posted a link to R-Studio. On a Linux partitioned NAS R-Studio for linux seems to give the best chance of recovery.

I think you're also saying I can make a USB or DVD linux-based R-Studio boot using my current R-Studio Network, even though it was primarily for Windows?

I'm not sure your license includes the linux version but they are two different things. I'm not all that familiar with R-studio, only that in the thread I linked to the poster booted linux and used R-studio for linux to access the drive. Not sure about a bootable linux USB flash drive.

I did not succeed in creating a bootable USB key on windows XP (I always have the message "No Default or UI configuration directive found !" (I tried with Lili, with UnetBootin, with Universal US Creator => same result"

 

where is the link you indicate with R-Studio for linux  ? with which software do you create a bootable USB key ?

 

I'll try on windows 10 to see if it's better ....

R studio for linux requires it to be run on a linux OS. They do have an Emergency iso image. I don't what the cost of the iso is though.

Here is the page that allows you do use R-studio in demo mode.
