How to run photorec on NAS with busybox (WD Mycloud) Topic is solved

[miknzau]

Hi,

I have a WD Mycloud Nas that runs busybox which I believe is a very stripped down linux, meaning I cant use apt-get to install photorec.

How do I run photorec? I have downloaded the files on to a USB and mounted that successfully but every time i try to run it i see this...

root@WDMyCloudMirror USB1_c1 # cd testdisk-7.0
root@WDMyCloudMirror testdisk-7.0 # sudo photorec_static
sudo: photorec_static: command not found
root@WDMyCloudMirror testdisk-7.0 # sudo photorec
sudo: photorec: command not found
root@WDMyCloudMirror testdisk-7.0 # photorec_static
-sh: photorec_static: not found
root@WDMyCloudMirror testdisk-7.0 # ls
AUTHORS README icons readme.txt
Android.mk THANKS jni testdisk.8
COPYING VERSION l testdisk_static
ChangeLog documentation.html photorec.8
INFO fidentify.8 photorec_static
NEWS fidentify_static qphotorec.8

So my question is - how to I actually run the photorec application on this device?

Thanks

Update: I copied the ARM version of testdisk/photorec onto a USB drive and plugged that into the NAS, navigated to the mount and typed "./photorec"

This worked, the file executes but then it fails trying to load the library libjpeg.so.62

libjpeg.so.62 is not there because BusyBox is so stripped down.

So then I found this site's instruction on compiling a libjpeg on the machine, but alas, the damn thing doesn't have gcc the compiler on board!

So what I really think I need as a copy of the library libjpeg.so.62 complied for ARM that I can drop into the /lib folder on my WD Mycloud Mirror

Can anyone help with that or see any other way around the problem?

P.S. ./testdisk runs fine but the partition is ex4 i believe so i cant use the undelete function of that app

Hi any chance someone can help out here?

Hi, is anyone able to help me with getting photorec going in this case?

[miknzau]

I would really like to be able to return this Western Digital NAS to the store I bought it as it has caused me these issues.

Before I can do that - I need to run photorec on it to recover the photos (about 7GB worth) that I copied to it and it's O/S deleted.

As mentioned above, I can run photorec but it stops because the stripped down linux on the NAS (Busybox) does not have the required JPEG library.

A comprehensive google search does not uncover the jpeg laibrary compiled for ARM processors anywhere (except for one dead FTP link) and I can't compile one myself because the unit has no compiler.

So I am pleading with someone (maybe the admin of this form might like to comment) to advise how I might get this Jpeg library onto the unit so photorec will run.

Thank you very much in advance.

Hi,

I would really appreciate it if someone could reply to this thread. I am asking something pretty specific here I know, but surely someone who is very linux savvy can contribute?

Thanks in advance.

Can you try using the library from http://www.cgsecurity.og/libjpeg_arm-no ... abi.tar.gz ?

Code: Select all

cd /usr/lib
tar xzf libjpeg_arm-none-linux-gnueabi.tar.gz
ldconfig -v

ldconfig should list libjpeg.so.62.
If it's ok, try to run photorec again
