Removed drives, reinstalled and keeps wanting to wipe the drives

Hi

 

I have a very old ReadyNas Duo.

 

I removed a 4TB drive from another RN102 drive as I stupidly installed a new 8TB drive without realising it would only format to 4TB as I had a 4TB drive in bay 1 already.

 

Anyway, thought i'd remove the 2x 2TB drives in the Duo and format the 4TB in there, copy everything across from the RN102, reformat that to 8TB and then transfer everything across again gaining my full 8TB drive back.

I didnt realise it would only format to 2TB, so thats a no go.

I have removed the 4TB drive from the duo and have tried popping one of the 2TB drives back in the duo and its trying to reinstall, looks like its formatting the disk. Is there a way for it not to do this, as obviously I dont want to loose all my files from the 2x2TB drives I have.

 

Help would be great, as I am in a bity of trouble,

 

Thanks

 

Rich

If I understand your sequence correctly, it shouldn't be formatting it, though it might be doing a file system check.  Was the NAS running when you pulled the drives?

 

You could shut down the NAS, and then try connecting disk 1 of the 2 TB set to a Windows PC, and use R-linux for Windows to extract the data.  https://www.r-studio.com/free-linux-recovery/  This won't work with disk 2, so if you don't see the files try the other disk.

 

 

You could also try booting up the NAS using the option to skip the volume check.  See pages 15-16 here:  http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf

 

If you want to try both, I'd use R-linux first (confirming you can see your files), and then boot with the other disk in slot 2 of the NAS.

I don't own a Mac, so I can't offer much advice.  You could try this, but it is not free: https://www.r-studio.com/data_recovery_macintosh/

 

You can download it for free though, and see if it finds your data before you purchase.  So you could

  1. confirm that R-Studio sees your data (w/o purchase)
  2. see if the Duo boots ok with the remaining disk
  3. purchase R-Studio only if it doesn't.

Re: Removed drives, reinstalled and keeps wanting to wipe the drives

I have had a look at the logs, looks like its wiped the drive.

 

Filesystem Size Used Avail Use% Mounted on
/dev/md0 2.0G 319M 1.7G 17% /
tmpfs 16k 0 16k 0% /USB

 

So a bit unsure about putting the other disk back in at the moment.
