ReadayNAS Ultra 4 data recovery after dying

Question

My 2011 Netgear Readynas Ultra 4 blew out the electricity and died recently. Either the PSU or the entire thing died. Inside were 4 disk with valuable data, in Raid 5.

The question would be, if I buy a 4-hdd docking station, can I recover the data on it with a raid recovery software? Or does anyone have a better idea?

Replacing the PSU is something I could only find on ebay for a lot of money. And plugging in another normal PSU is something a bit over my head

Hope someone has a good tip to get my data off,

Do you have a saved copy of a log file?&nbsp; That will tell you which you were using.&nbsp;The recovery methods are quite different because of the different volume structures used (LVM/MDADM and GPT for 4.2 and MDADM and BTRFS on OS6).&nbsp;The easiest recovery method, assuming the volume was not damaged when the unit "blew up" (which will affect any recovery method) is to put the drives in a replacement ReadyNAS.&nbsp; But you'll also need to know which OS you were running to do that.&nbsp; And, of course, you'd be buying used equipment, which always carries some risk.&nbsp; And there is the question as to whether you want to continue using a NAS from a company that has basically abandoned it.

OS-6 would have required you to back up all the data and use a special conversion procedure.&nbsp; Then rebuild the NAS and restore all the files from backup.&nbsp; OS-6 has a very different look from the older Frontview. Likely something you would remember doing.&nbsp;&nbsp;
&nbsp;
In addition to&nbsp;Sandshark's suggestion, you could use RAID recovery software in a Windows PC. As you posted, you'd need to get suitable USB enclosures, and also enough storage to offload the data.
&nbsp;
ReclaiMe will recover the files for either OS-6 or OS-4.&nbsp; R-Linux for Windows will recover OS-4, and is significantly cheaper.&nbsp; But you can download both first (before purchase) and see if either can recover your files.&nbsp;
&nbsp;
Also - if you can connect even one disk to a Windows PC, then you can check them (one at a time) with vendor tools.&nbsp; Windows won't mount them, but the vendor tools will find them.&nbsp; Then you'd have some confirmation that the disks are still ok.&nbsp; Always a good idea to label the disks by slot as you remove them.

Were you running the stock 4.2.x firmware?
Or had you converted the NAS to run OS 6?

StephenB&nbsp;I'm afraid I can't recall, it's been a while since I had updated it, that's for sure. But it blew up after I had not touched it in a while, could you help me with the implication of either OS?&nbsp;But I'm guessing 4.2
