No Disks Detected (RND4000-200NAS)
My ReadyNAS NV+ v2 was making fan noise so I decided to shut it down and blow it out with compressed air.
Powering it on, it displayed "No Disks Detected". Based on one response on these forums I tried replacing the fan. I've also tried taking my drives out, inserting a scratch drive and doing a factory reset via the menu. I can see the chassis via RAIDar, but it doesn't report any disks as being inserted.
Are there any troubleshooting steps left or is the backplane somehow just gone now?
And if the backplane is gone, what chassis can I replace it with that would be compatible with the RAID off the drives that were in there (which I hope is still good, can't really tell).
Solution found:
The cheap external power supply I bought off of Amazon failed in some strange way (it must have been producing enough power to light most everything up, but the drives spinning up must have drove the voltage low and it failed or something electrical that rhymes with that).
I bought a whole additional case off of ebay, but it turned out all I needed was the power supply.
There was actually another thread that I found which suggested that this could be a power issue but they suggested plugging the unit into a different outlet. I didn't make the connection that it could have been the external power supply or think that the power supply could even have a failure mode where it started to not produce enough power rather than just failing outright.

All currently shipping ReadyNAS use a different file system setup, so none of them are compatible.
It is possible to temporarily mount the disks in a new NAS so you can offload the data. That requires assistance from paid support - not sure what they'd charge. https://kb.netgear.com/29876/ReadyNAS-Migrating-disks-from-RAIDiator-4-1-or-RAIDiator-5-3-to-ReadyNAS-OS-6
If you connect the disks to a PC (likely using USB adapter/docks) you could also use R-Studio to access the data. https://www.r-studio.com/

I'm not thinking of much - perhaps Sandshark might offer a suggestion.
What about USB flash recovery?

I don't see one for 5.3 though.
Or would a RND4000-100NAS NV+ "v1" be able to read the drives?
