ReadyNAS NV+ v1 Replaced Drive, Won't Boot
Hello, I have the ReadyNas NV+ v1. It came with four 750Gig drives. I saw a warning message on the front of the unit that one of my drives was experiencing errors, so I removed drive #1, the un...
That's the code for "Boot loader fails to locate valid RAIDiator image, TFTP or USB OS image recovery required." You need to do a USB OS recovery. For more LED codes, see here: ReadyNAS LED Language.
Now, why that happened concurrent with replacing a drive is another question. Maybe just coincidence, but how likely is that?
How do I do a USB OS recovery?
I suggest that if you want to try USB recovery, you should do that with only the new 1 TB disk installed in the NV+ (removing all the old disks, and labeling them by slot). The procedure is here: https://kb.netgear.com/21400/RAIDiator-4-1-USB-Recovery-Tool. That preserves your existing data while you bring the NAS back up.
You might also want to test the new drive with vendor diags in a windows PC (using WD's Lifeguard program or Seagate's Seatools).
Another option is that you can mount the disks in a normal X86 PC running linux (though you do need to connect all the drives to the PC). Most PCs can be booted up on linux "live" disks, leaving the main OS intact. Then you can offload the data. That procedure is here: http://home.bott.ca/webserver/?p=306
