RND2150 died at power outage. How to save my data?
I've had my ReadyNAS Duo 2150 since 2009. I've replaced disks a couple of times, and now I have two 1TB disks (mirrored). A couple of days ago, we had a short (2 minutes) power outage. After that...

It took a while for the power supply to arrive, but now it's here. Happy days, the NAS is alive and the data is still readable! :smileyvery-happy:
I'm busy copying all the contents to a USB drive now, to have a current backup. During copying, the NAS unexpectadly shut down at one point, but after power on it's working again and the copying continues.
I'll definitely look for a new solution to my shared data. Perhaps a new NAS (where the disks can be read even if the NAS itself dies), or perhaps some kind of cloud solution. My primary uses are as backup of various data from our laptops in the family, primary photo storage, and music files server for our HEOS system.

There are no new models that are compatibile with the format on your disks. Used v1 platforms would be, but not all used equipment sold is completely functional, and often there is confusion over v1 and v2 platforms. So there are risks there.
After market power bricks can be purchased. One is here: http://www.amazon.com/Netgear-ReadyNAS-External-replacement-adaptor/dp/B00QC42N6M Of course you should be careful to check the specs, etc. against your existing brick before you use it.

It does not require a desktop PC. You can use a USB enclosure or a USB->SATA adapter kit. For instance this: http://www.amazon.com/Sabrent-2-5-Inch-5-25-Inch-Converter-USB-DSC7/dp/B0056JBBKS You do need one with an external SATA power adapter (which the Sabrent includes).

Thank you for the support so far. I'm still stuck, though.
So far I've tried two different USB-to-SATA and the Linux Reader. No luck with either of the two HDD that were in the NAS when it died. Also no luck with a one year old HDD I kept as backup when I replaced it with new, larger HDD. To me it looks like the Linux Reader is unable to read the NAS File System. Obviously (from reading these forums), it should be able to read the drives. Am I doing something wrong?
Here's the full description of what I'm doing:
I'm trying to read a 3.5" hard drive which has been used in a NetGear ReadyNAS Duo RND2150.
I'm using a Windows 10 laptop with a USB-to-SATA HDD docking station to connect the hard drive.
I'm using DiskInternals Linux Reader (x64) 2.3.0.3
I've tried reading the two 1 TB drives which I've been using (mirrored) in the NAS until the NAS died a couple of days ago in connection with a power outage. No luck. I assume it's possible that both these drives became corrupted at the crash, but rather unlikely?
However, I've also tried reading a fully working 500 GB drive (described above) which I replaced with the 1 TB drives a year ago. This doesn't work either (identical behaviour). This is what happens:
Using Windows Explorer I can't see the hard drive.
Using DiskInternals Linux Reader (x64) 2.3.0.3 I can see it listed in the Folders panel as a Physical drive named ST3500320AS.
The status bar at the bottom shows a warning "File system is not supported".
In the right panel, the drive is listed under Unallocated space as:
ST3500320AS, at end
33,83 Mb
In the right panel, the drive is listed under Physical drives as:
ST3500320AS
465,76 Gb
Disk 1 (000000000033)
Double clicking on either of the two in the right panel gives me a popup saying:
Can't open disk: ST3500320AS
Check the disk and try again
Any ideas?
I'm about to try the replacement power brick road as well, but I haven't been able to find one here in Sweden and it's a couple of weeks delivery time if I order it from Amazon UK:
http://www.amazon.co.uk/Netgear-ReadyNAS-replacement-supply-adaptor/dp/B007Z5E48W
I'm not completely sure it's the appropriate one for my NAS though. There's no description about Watt or Ampere for it.
Perhaps I could get this one instead, which is generic but which has the correct specification when I compare with the writing on my possibly damaged power brick:

Do you recall if the NAS was using flexraid or xraid? xraid is the default. Linux Reader doesn't work with flexraid (but should have seen the OS partition, and didn't).
It is possible that the disks became corrupted when the power failed (I lost a data volume on a duo once when it lost power unexpectedly). But I agree that doesn't explain the old 500 GB disk. This system was running 4.1.x firmware?
I've confirmed the power specs of your two choices, but I haven't found any specs on the barrel plug. Note that the UK brick is also generic (myvolts, not netgear). If you google "netgear 332-10192-01" you might find more choices.

No, I don't remember making the choise between flexraid or xraid. I bought the NAS and two hard drives and configured them to be mirrored (RAID 1 I believe). It's 7 years ago, so I don't remember what the procedure was. If the setup procedure indicated that one is better than the other for some reason that made sense to me, I would have selected that. Otherwise I would have kept the default. So, I probably was using the default (xraid).
I've been using firmware 4.1.12 for at least a couple of years.
I'll probably take a trip to the Swedish store Elfa during next week and buy the power supply I linked to in the previous post, or some other they have if the plug doesn't match.
- myldApr 21, 2016Aspirant
Just a quick update. The visit to the store failed, since they don't have the power supply I need in stock. But now I've ordered one that I hope will work. I'll update again when I've received it (hopefully early next week).
