Thanks to Steven Lilly for providing a video tutorial for this method, link at the end of the article. You now should have a working NAS again ! Then shut it down, remove the USB drive and start it again !

Keep the USB plugged until the usual interface shows up. After the reboot logo showed up, you can release the reset button, watch for the hard drive blue activity light to see if you succeed.įinish the installation, Wait for the firmware to do his business, it should take about 5 to 10 minutes, the unit should turn off and back up again, If it’s not turning on, start it manually. While pressing the NAS reset button, power on the NAS, keep holding for 60/70 seconds. Install the firmware, Then, plug your USB key to the back, on the top USB port of the NAS. Make the bootable recovery USB, you first have to format your USB key to FAT 32, then extract the ix4-200d-recovery.zip file to the USB support. Two disk are recommended to rebuild the raid group directly, but if the installation fails, you can try again with only one. Prepare your NAS, Remove every drives except the drives in the slot 1 and 2, they will be the targeted disks for the firmware install. The needed backup files (Files and mirrors linked).


You may have accidentally erased your whole NAS drives or just been a victim of a software bug, but for a reason or another your Iomega NAS may have lost his firmware.
