Hi Guys, I have a Netgear readynas rnd2000 bought some time in 2010.I have 2 2TB hdd configured as RAID0. So the storage was 4 TB.Now it seems the device stopped working.it is not getting detected on the network or RAIDior.So i removed i HDD and tried accessing it using Centos 6.7 and ext2-fuse.But the PV was detected but due to the raid configuration, the vgs are showing and 3.5TB and not 2 TB. It says " Physical volume /dev/sdb3 is too large for underlying device.As a result i couldnt recover any data.can you suggest any options to recover the data?i am also wondering whether if i buy a latest netgear and connect these hdds will it work?

You cannot migrate the disks to any current NAS, but you could look for a used duo v1 or used nv+ v1. If the NAS isn't powering at all (no lights, etc) it might be the power brick. If you google, you can find replacements fairly easily. RAID-0 is particularly vulnerable to disk failures (though that doesn't seem to be your issue). So if you do manage to get the data back, you should definitely put a backup plan in place.

Thanks for the reply. When the device is powered on, the fan runs continuosly. The power button light blinks and thats it. Nothing else. So it is not the issue with the power brick. (Btw i tried swaping it too without any luck).

if i buy a second-hand NetGear ReadyNAS Duo 2-Bay (Diskless) RND2000 and connect both my HDDs, will it start working right away? Or is there any setup/configurations that has to be made? thanks...

Before you get a used NAS, I'd try powering down and removing both disks (labeling by slot). Then power up. If RAIDar finds the NAS and reports "no disks" then the problem is likely with the disks, and not the chassis. If that turns out to be your situation, get a scratch disk and try doing a factory install with only that disk in place. If the works normally, then for certain the problem is on one or both hard drives. muxyd wrote: if i buy a second-hand NetGear ReadyNAS Duo 2-Bay (Diskless) RND2000 and connect both my HDDs, will it start working right away? Or is there any setup/configurations that has to be made? thanks... The NAS boots from an OS partittion on the disks. The boot flash also includes an install package, and if the firmware version in the flash differs from the OS partitoin, the system will attempt to overinstall the flash version (either upgrading or downgrading the OS version on the disks). Normally this is not a problem - settings and data are preserved. Though if you are migrating disks to a NAS and don't know the firmware version that was installed, then it is best to start with a scratch disk. Then after the default installation you install firmware that matches the old NAS. The result is that the flash package matches what is on the disks, and the system won't attempt to overinstall. Also label the drives by slot before you remove them - you want to preserve the order.

It was already tried out the below 1. removed both the disks and tried booting. 2. Tried booting the device with only disk in slot1. 3. Tried booting the device with only disk in slot2. 4. Tried booting the device after swapping the disks. but none worked. the device is not detected by RAIDar. Even i tried connecting the device directly to my laptop ( using RJ45 cable), but the network device icon my machine showed the red cross. when i connected the HDDs, the partitions were detected properly and dont think there is any phyical damages

Thanks mdgm..

If I can arrange a temporary NetGear ReadyNAS Duo 2-Bay (Diskless) RND2000 and connect both my HDDs, will i be access my files??

If so, I know someone who has one which I may be able to borrow for someone. But it is not easy. So what to know if it works before I try it out..

Please advice.

  Impossible to know for sure before you give it a try.
  
  It must be the same kind of Duo: http://www.rnasguide.com/2012/01/09/how-to-tell-whether-i-have-a-duo-v1-or-duo-v2-or-nv-v1-or-nv-v2/

  Does the system show on RAIDar if you try booting to tech support mode?

    What ever i do, there is no change.
    
    first the powerbutton, act, disk 1 and disk 2 lights blink together twice. Then the disk 1 blinks twice. and after that the powerbutton, act, disk 1 and disk 2 lights blink together twice. This process is continued as long as you keep the device powered on...
