RNR4000 (ReadyNAS 1100) - Disks Not Readable
Hello, My device was shut-down due to psu failure. I had ordered new psu from amazon and replaced it with the damaged one. The device turned on however Drive 1 and Drive 4 are not readable (it st...

Connecting the drives to Windows PC is not working, as Disks are not being initialized due to linux format of drives. Should installing the tools you've mentioned will be able to read the drives and process tests?
As I am avoiding playing around with the drives that may increase the risk of loosing the data.

Following are details from NAS:

PS* The device was running on default confiuration, I have 4 Drives and all drives are of size 1TB each.

Windows itself doesn't support the file system, so the drives won't mount. And you shouldn't initialize or format them of course.
The tools will still see the drives, and the tests I suggested are read-only - not destructive.
Drive 1 - Seagate - When I connect it with system, there is no sound of detection (when you connect any device to USB ports, there is a ding-ding sound, something like that) from the system. And SeaTools doesn't detect it as well, and it is not appearing in Disk Management.
Drive 2, 3, and 4 - WD - Detected and I ran the tests using WD Lifegaurd Tools. Please see screenshots below.
When I connect all 4 drives to the Netgear, in netgear panel, only Drive 2 and Drive 3 marked as green checkpoint (small circle), the Drive 1 and Drive 4 has grey checkpoint (small circle).
What do you suggest?

That suggests drive 1 has failed. That could have happened before the PSU issue, though a power surge related to the failure might also have damaged it.

Although Drive 4 is passing the tests, the RAID might be out of sync.
I'd first try to boot the NAS w/o disk 1, and see if anything else changes (you can put disks 2-4 in their original slots, and boot with slot 1 empty).
If that fails, you should look into data recovery - R-Studio for Windows would work, and is inexpensive. You can download it, and see if it can recovery anything before purchasing. Netgear also offers a data recovery service.

I switched off the device, and restarted it again, I am not able to access the panel, the username (admin) and password set for it that was working before, is no longer working. Weired.
The password recovery page is not able to reset/recover the password due to security of the device set.
What do you suggest? How to reset the device and password without affecting the drives data?
