Corrupt root and cannot setup
Am looking for help to start my NAS again. I am in the stage where I already did a hard factory reset, with the pin at the back. Even that, when I boot, I get "corrupt root" message on RAIDar. Follow...
That disk is already partitioned so as a precaution we gave the corrupt root error rather than blindly formatting it. Some users are unaware that the NAS needs to wipe the disks.
A factory default (wipes all data, settings, everything) or hooking the disk back up to a PC and deleting the partitions off it would have resolved this.Seeing that you didn't have any data on the disk I just wiped the partition table off the disk and rebooted the NAS. It should do a brief check of the hard disk, enter a 10 minute countdown and if you haven't chosen the RAID mode using RAIDar (or unplugged the power to abort) by then proceed to wipe the disk, partition it, setup the RAID, install the OS etc.
Try testing the disk in a PC with the vendor tools (seatools for seagate, lifeguard for western digital). Use the "write zeros" test too (which is useful in determining disk health, and also ensures a clean disk for the NAS).
If it passes, then try the install again with the zeroed disk.
Hi Stephen,
I already did all that with two seagate disk. I even bought a new disk, this time a Western Digital, and no luck. Now, am testing with an SSD Kingston, still not working. If I put it on remote support mode, can you access and just set everything to factory default ? Once, it was accessed to activate TEAMING. Though it was working well for 2 years, it suddenly failed on a reboot, with no apparent external factors (no disk or config change). Cooling fan is working well.

Sorry, I don't work for Netgear so I can't do that.

The warranty is 3 years on the ultra, so you should check on the warranty status right away.
I was able to telnet in under Tech Mode. From there, I have no idea what to do.

Are there some commands that I can type in to get things back up. The NAS is just sitting on my desk doing nothing, and it's brand new (from a warranty exchange).
