ReadyNAS202 is not connecting to the network
My ReadyNAS 202 has suddenly stopped showing up on the network at the assigned IP address. Almost everything on the device, including the main ethernet port activity lights appears to show things wor...
Thanks for the response Stephen.

I can obtain various JRE versions, but note RAIDar states it needs at least JRE 11 - hence I expected 17 to be fine.

Yes

Of course, many times.

Thanks. That rings a bell from when I had to do recovery from the MyBookWorld NAS.

Netgear hasn't maintained RAIDar. The JRE I posted works with RAIDar 6.5 (and everything newer I've located will not).

I'd like to see if RAIDar can find it.
If it doesn't, then power down and remove the disks (labeling by slot, so you can return them to the same bays later). Then power up diskless, and see if RAIDar finds them with a no-disks status.
Make sure the NAS is powered down before adding back the disks.
Okay I will try with JRE 8. This is the error I got from RAIDar - and it is a bit confusing as it states OpenJDK 11 or later, but then 64-bit JRE 6 or later (which really makes no sense - I'm a Java VM developer - as you can't require something from 11 but still run on 6.
Thanks
RAIDar won't run. It flashes up blank command window which then disappears and nothing happens.
Ugghh. There was a hidden modal dialog from a previous run that stopped RAIDar from launching.
RAIDar could not see my ReadyNAS202 with the disks, but it can without them. I was hoping to be able to see some error logs to find out what went wrong but I guess they are stored on the disks. 😞

Perfectly correct! This confusion is home-made by Oracle, the Java maintainers, and exists for a longer time: OpenJDK is and the closed source JDK is currently on SE 21, while the Java Runtime Environment (JRE) for all operating systems, is on v8 - currently recommended Version 8 Update 391, Release date: October 17, 2023. Hope you don't mind that the most users do indeed use JRE, not JDK 8-)
Good ol RAIDar 6.5.0 code does work here on an up2date 64 bit Windows 10 like a charm with JRE8u391 StephenB or does yours not discover the ReadyNAS? Something I've seen randomly, too.

It generally does work, but I have occasionally seen it miss a NAS.
Thx for the pointer on u391, I'd missed that update.
