hi, i want to try this method
I think I deleted my files or have trouble making raid5
Could you help me?
In Turkey our company doesnt allow us to help this kind of recovery process, so If you are not good at Linux commands I advice you to use R-Stuio.
Its really easy to use and you can easly find lots of document with a little google search!
Thank you very much, it really helped!
Ran it on TS-869 Pro with 8 x 3Tb in RAID 6 – worked perfectly, but took almost 3 days.
First of all excuse my english
Thanx for this guide, i followed step by step and i recovered folders and files deleted by error.
I just wanted to make a aportacion: in step three, when I execute photorec or testdisk, i get a permission denied message, so you will need to chmod the testdisk folder before execute it.
Your definetly right, so I fix this document once again.
I tried to run photorec on my QNAP TS212P but got this error: cannot execute binary file
Do I need to use this version instead of the x86_64 version (from the TestDisk/PhotoRec downloads page):
Marvell 88F628x Linux 2.6.32 Synology DS111, DS211, DS212+ NAS, Seagate BlackArmor NAS 220, QNAP ARM based including TS-410
+Before trying to recovery, can you check if your files still in your NAS or not?
+For photorec, try to install “Linux, kernel 2.6.x i386 version and it should work!”
+Also no need to panic; you can easly restore datas with recovery softwares on 1 or 2 HDD models. If you have RAID 1 or single HDD, just plugin HDD to a PC and follow my “I Accidently Delete a file, so is there a Chance to Recover Datas?” R-Studio Recovery document;
+If you have RAID 0, you should plug both HDD’s on PC.
Ps: Plug out HDD when Qnap power is off, and before power on your NAS again, plugin back HDDs back again to the same slots;

Hi, do you have a way to submit questions? I had typed up a comment/question earlier here but I think it got lost or didn’t submit correctly. I typed up my question on the QNAP forums but I haven’t gotten any response.
I am trying to figure out what has happened to my drive and the best way to recover it. I am running Test Disk partition recovery on it now to see what it finds. It does show some partitions on it but only the “qnap” files show in the first partition so that is why I am running a deep analysis but it will probably take until the end of the weekend to finish..
Hi, will this process overwrite the contents of my external drive?
No, but you better use a fresh external HDD
So I went through everything you mentioned here and read all the comments. Nothing worked. I even tried installing all of this into the sbin folder. I tried the 64 bit, and the NAS one for Synology and Qnap. Still nothing. The file would not execute. Then I tried the 32 bit version because I have the same exact Qnap TS-695 Pro. Picked it up on Ebay.
The 32 bit version of this app worked perfect, just perfect.
There is more to this story. Recovering 3 gig takes 20 days on a slow system and 10 days on a kick ass I7. The issue is who wants to leave their computer running for 20 days straight? Well guess what? The Qnap mentioned above has a VGA port and it displays console/terminal ssh. So all you have to do is plug in a USB keyboard, connect the VGA port to a monitor, and do all this from the Qnap device. That way you don’t sacrifice 20 days of your PC/server to recover the files. Let the NAS device do it for you. When you disconnect the VGA monitor and keyboard the NAS continues extracting. When you reconnect and touch any button but the Enter key, it refreshes and your session is still running. Nothing shy of awesome in my book. I spent four days trying to figure out how not to tie up my PC’s to accomplish this.
20 Days for 3GB , wow thats a long time
I had unintentionally sent around 600GB to the Qnap Recycle bin and for some weird reason the NAS screwed my Data , so to recover this data , based on what your saying (in theory) I would have to let in run for 4000 Days or 10 Years to recover it all
Shall I post back in 10 years to tell you how I get on ?
So my deleted 600GB would take 10 years in theory ?
does photorec work on a QNAP based on ARM ?
Thanks for your reply.
For anyone who needs to recover files on an ARM based Qnap (TS212 for example), download the “Marvell 88F628x Linux 2.6.32″ version from the Testdisk page.
After you have copied the folder to the QNAP and carried out the chmod function you will probably encounter an error like “Terminfo file is missing” when trying to run photorec.
If you run these two commands and try running photorec after, it should work…
Hope this helps!

Hi. I get stuck at [Run PhotoRec (photorec_static) in the shell by issuing a ./photorec_static command] with an error of cannot execute binary file. Can you give a hint?
