Hi Team,I have an RND4000 NV+ 4 Bay. It is stuck on boot, I have done the initialisation of OS already, still the same. I have downloaded both the oldest and newest radiator bios firmware files from the support page. Loaded them one at a time on a blank FAT32 format USB in the root directory, then placed the USB in the front USB socket on the NAS unit. Held the power but down for 20 secs until the display indicated USB boot mode. In both instances the sequence stopped with an error "BIOS INFO: OS Index ERROR". This would happen with or without disks being in.I cant find any reference to the error.RAIDar cant see the unit. Any suggestions would be helpful, the disks have data on them.Pete

That's not how you create a USB recovery drive. But how you do it depends on which version of the NV+ you have, which is the reason for StephenB 's question.

Thx Stephen for the response. It has NV+ on the front grille.

I suggest powering down and removing the disks in the NAS (labeling by slot). Then power up. Normally you would then see a "no disks" message on the LCD screen of the NAS. Are you seeing that? If you are, then I suggest powering down again, and reinserting the disks. Then power up. Let us know what is on the LCD screen (if anything). Also install RAIDar, and see if it can find your NAS. If it can, let us know what status it is showing (posting a screenshot is a good way to do that). https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar

After removing the disks and powering on I see the message 'No Disks'. I can power the unit down by pressing and holding the power button. I insert the disks again and reboot, the units remains 'booting...' and hangs there.When I engage raidar it cannot see the unit and asks me to rescan.There are no other NAS units on my network. I assume it cannot see it as the unit has not reached the stage where an IP address is established. I can NOT power the unit down by pressing and holding the power button when it is in the 'booting' phase so I have to remove the power cord to power it down.Thank you again for your interest in my challengePete

  I have a spare drive now - its a Seagate Barracuda 160GB. I'll remove the data drives and number them. I will place the spare drive in a caddy and await instructions.
  
  Many thanks in advance - Pete

    Just put the drive into slot 1, and then boot up the NAS and do a factory default. This normally will do a fresh factory install on the NAS. If that works (and the system boots normally), then the boot issue is actually due to something on the operational disks, and not the flash memory.
    
    If you don't recall the factory default procedure, see pages 23-24 here: https://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
    
    Note if the disk is unformatted, then the system will automatically do the install on power up (no need to use the boot menu in that case).
