Help [!] Data recovery issue
My RND4000 (3x2T) wouldn't start when I returned from a recent trip. I suspect a PSU failure. Most of the data contained therein are replicated elsewhere, but not all. I'd like access to my drives to...
As it's not a warranty replacement we would always need to charge for data recovery. Attempting to recover data is an advanced process requiring an advanced set of skills. We don't just need to know a set of commands. We need to make judgment calls as to what to do and when, be able to react appropriately to any problems identified etc.
Unfortunately it's not as simple for Sparc as it is for x86. With legacy x86 systems moved to current OS6 x86 systems you can move the disks across and the NAS will try to boot the old OS off the disks to allow you to copy your data off. Quite a straightforward process if it all goes smoothly. Note this is assuming that the disks are fine and that the RAID, OS and volume on the disks are also fine. This may not be the case.
If the data's important (e.g. patient medical records) then presumably you'd backup the data rather than store it on the one device so restoration from backup would be another option.
With a ~ 10 year old device it was bound to fail eventually. Some units do last longer than others but by that age the chances of hardware failure would have risen a lot.
They did not indicate why the contract would be required. There is NO evidence that the array is damaged or impaired.
I had seen the posts about PSU replacment. I don't have the time to do wire mods and I agree the replacements are pretty overpriced.
And, I don't have a Linux box. I'm just a doc. I'm fairly adept with Windows but have little knowledge of the ways of the Bash prompt. My last coding experience was C+ (I'm sort of old.)
$99 for the modified supply isn't too bad actually, I've seen a lot higher.
Looking over the thread, I see I made an assumption that you have a v1 NAS (4.1.x firmware). You should check this thread, and confirm the model 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/.
Also - are you the original purchaser? If so, when did you purchase?

As I tried to say, you can get a linux "live" USB boot flash for free. That will let you boot your Windows PC under linux (leaving the normal Windows boot completely unchanged). Linux shell commands of course would have to be learned (though most of them are the same as unix, so they go back a long way).
It would require some time investment.
Yup: v.1. I am the original purchaser: ca. 10 years ago. The box served me well.
I may well just need to do the PSU thing. But, it's unfortunate there is not some simple way to extract data from v4.x under v6.x.
Much thanks.

This service action still applies - so check to see if your serial number is in the indicated range. https://community.netgear.com/t5/Using-your-ReadyNAS/Service-Action-to-Prevent-PSU-Failures-in-ReadyNAS-NV-NV/m-p/568987/highlight/true#M90811
If you happen to be in that range, Netgear should replace the PSU for free.
It's not. Already checked.

Yes. It's easier with the OS 4.2 because they run x86 CPUs - and even there, the support is limited to mounting the volume read-only. One challenge with 4.1 is that the RAID mode is tailored to the hardware acceleration hardware in the sparc chipset.
Ultimately it's up to you to decide what's important enough to backup.
I'd recommend keeping multiple copies of any important data when using a brand new system let alone one that's about 10 years old and much more likely to fail soon.
We feel it's important to offer a service to help with recovering data from legacy systems, but when our support needs to get involved it tends to involve a lot of work. We do our best to recover data, but may be unsuccessful.
