Re: Synology missing partition
scanning with testdisk, option : cylinder boudary-> no (or perhaps alignement-> no depending version) you should in quicksearch or deepersearch recover an md3 with another linux partition.
Don't "write", i just need to diagnoze first.
Edit : will be disconneted soon for 24 hours. Please be patient. Precipitation is not good in datarecovery.

Re: Synology missing partition
Thought you already removed it from the NAS. I need linux command line so if you remove it from synology, connect on Linux OS.
Did you have only one disk in the first device, or was it a real raid1 ?

Re: Synology missing partition
On the first device that was only one disk. That was one bay unit.
So I need to disconnect disk from synology.
Then coonect to pc running Linux OS? ( can you recomend any)
Then i can try to give You ssh connection.?
Let me know if this steps are right.

Re: Synology missing partition
Best solution is to run PC with linux and connect your disk inside your computer (quickest).kostrzu wrote:On the first device that was only one disk. That was one bay unit.

Ubuntu is good, and user friendly.kostrzu wrote: Then coonect to pc running Linux OS? ( can you recomend any)

- I am professional in datarecovery and if I do the job, it's not free. If I help you, there in the forum, it's usefull for everyone and it's free because helping community. If you choose first option, contact me by Private Message or by mail through my website.
- I won't be connected until tonight or tomorrow.
After connecting your disk and launching gnu/linux,
1/ Verify what's the name of your disk with
Code: Select all
sudo sfdisk -luS
3/ Launch
Code: Select all
sudo ~/testdisk_static /dev/yourdisk
5/ Select table intel and perform simple Analyse / Quicksearch / Deepersearch.
6/ Give feedback about what testdisk found on these steps
7/ Do not use "WRITE" because it's only for diagnose purpose.
