ReadyNAS RNDU 2120 Ultra 2 not Responding
When connected to power supply my readynas ultra 2 is just running at full speed with the fan, but it does not boot at all. I'm not able to reset it or anything. The blue power button is just lit and fan running at full speed but nothing happens. It has anything to do with whether there are disks in cabinet or not. I have two discs in it, mirrored (RAID1). I guess something in the NAS has broken (maybe due to overheat). I have lifetime family photos on it and can now not access them. Have no other backup, just the two discs in the NAS - which I hope are still are fine. What are my options for recovering the data? For info I have bought a new NAS (Synology 716+II, and also a new disc of same size as the ones in the "broken" Readynas). Any chance I will be able to read the old discs in new Synology NAS? If that will not work - Can I read and copy the old disc by connecting via SATA to a PC?
SOLVED!
I downloaded ReclaiMe Ultimate, great tool. All files have been saved.
Thanks for all support.

If you are sklled with SSH, you could possibly mount the volume temporarily It'd be safest to do that if you connect the drive as an external drive. Since you are using RAID-1, you only need to connect one disk.

Windows can't read the disk format directly. Vendor tools (seatools for seagate, lifeguard for western digital) will see the drive, and let you test it.
I think r-linux for windows will be able to read it (http://www.r-tt.com/free_linux_recovery/).
There is a procedure to move the disks across to another x86 ReadyNAS e.g. RN312.
But if there is a problem with the disks or what's on them then you may still need assistance.
- Thanks for all input. I plan to try the disc to PC option next week.
Summury so far = have still not manage to recover the ReadyNAS files.
I downloaded r-linux to my PC, then scanned one of the ReadyNAS discs via a SATA docking station. Two volumes were "recognized" (took quite some hours to scan): Ext3 and Ext4. There were also a few other partitions (believe it said they had unreadable format)
Both the recognized volumes each had a ROOT and a METAFILES folder. Only the Ext3 ROOT folder had sub-folders and files that were readable/understandable to me (e.g. bin, c, dev, etc, frontview, home, initrd, lib, lib64, root, sbin, sys, temp, etc). I recon these files were original ReadyNAS folders and programs. The Ext4 ROOT consisted only of files named like "$Inodelndx000038f8". The ext4 METAFILES folder consisted of lots of files named like "$BlockBitmap0000.bin", "$BlockBitmap0001.bin", etc.
I dont know what I should do next. Any suggestions?

This is the OS partition, not the data volume.
You could try a different software package. Several people have had good luck with ReclaiMe, though it is expensive. You can see what it can recovery before you buy though.
Netgear's recovery service is another possibility: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service?cid=wmt_netgear_organic
