My ReadyNas 102 won't complete boot. Blinking power button

I had 2 4tb disks configured as one extended drive of 8tb with a bunch of shares.

Meaning you had set the unit up in flexraid using RAID-0?  If that is correct, you shouldn't have tried to boot the system with one drive.

RAID-0 has no redundancy, and if either disk fails you do lose all your data.  You always should have a backup of your data (since no RAID mode is enough to keep it safe).  But it's particularly important if you run RAID-0.

Something bad is going on with your network access.  One obvious thing is that the NAS is using an incompatible IP address.  If your PC is using 192.168.100.x address, the NAS should be using a 192.168.100.x address also.  But it's using 169.254.116.x.

• How did you get the logs?  Did you use RAIDar, or did you manage to log into the web admin page?
• Do you know if the NAS is configured to use DHCP?  Or did you configure a static address
• Is there any evidence that the NAS was using a 192.168.100.x address before or after Dec 2?

Is there any other way of accessing the contents of the drives?  Most of the data was fortunately backed up on a sepearate archive drive... I'm just missing a couple of folders that I'm desperately trying to gain access to.

I suggest powering down the NAS.  Then test the drives in a Windows PC using vendor tools (Seatools for Seagate; Lifeguard for Western Digital).  That will give you some confidence that the drives are ok.  Label the drives by slot as you remove them.  You can connect the drives either using SATA, or an inexpensive USB/SATA adapter or dock.

While the drives are removed, power up the NAS.  Check that RAIDar gives you a "no disks" status, and that you have a valid IP address for your network.

If the disks pass the diags, then put the into the NAS (while powered down) in their original slots.  Then see if you can boot the system in tech support mode - using the instructions on pages 20-21 here: http://www.downloads.netgear.com/files/GDC/READYNAS-100/ReadyNAS_%20OS6_Desktop_HM_EN.pdf

If that works, you can then try using paid support (via my.netgear.com), and see if they can resolve the issue.  They can access the system remotely if it is in tech support mode.  Ask for per-incident support, don't get the gearhead support package (which doesn't cover what you need).

You could alternatively try connecting both disks to the PC, and use ReclaiMe RAID recovery software ( https://www.reclaime.com/ )  You can see if it can find files on your data volume by downloading before you purchase.

Note that if the disks are intact, you can purchase a new OS-6 NAS (for instance an RN212) and migrate your disks to it with the NAS powered down.  However, migration will only work if the disks have no corruption (and of course are working).  It's not clear that your disks do.
