ReadyNAS Duo – LED Patterns

By dbott | November 8, 2009

From chirpa on the ReadyNAS Forums:

LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by a 1 second delay, followed by a number of slow blinks.  The number of slow blinks will be the error code.

Current error codes:
1 – Vendor mismatch
2 – No disks detected
3 – Bad contents on root partition of disks
4 – Flash error
5 – Unsupported RAID configuration

    Hi there,

    I have a ReadyNAS Duo, would not boot after being off for a few weeks when I was on holiday.

    Power LED has a steady on/off fading rapid blink, doesn’t ever go off, but fades. This is after startup with the fan on high and the LED blinking solid on/off.

    Any ideas?

    Netgear support doesn’t appear interested in actually listening to my symptoms. Tried firmware re-install and no change.

    It could be a flaky disk. Try testing your disks as per these instructions:

    If the disks test okay, you may just need to perform a USB Boot Recovery:
