ReadyNAS boot failure - pulsing power LED
Hi there
I've had my ReadyNAS Duo for about five years. Until the other day, it's given me next to no problems, but I've currently got a serious issue and was after some help please:
On booting, the ReadyNAS does it's usual thing of the fans going into high speed, and the blue power light flashing quickly. The fan then settles down normally, but the blue LED then starts pulsing on and off five times, followed by a single flash of the small led below it (?Activity light). I've tried taking out one of the drives, which gives me a pulsing blue LED followed every so often all four of the green leds on the front flash at the same time, three short, then three long. Can someone help me interpret this? I should also add that I can't connect to the ReadyNAS via Frontview, and the ReadyNAS isn't discoverable via Raidar. In recent weeks, I've been getting SMART errors on one of the disks, so I guess it's something to do with a drive failure?
Thanks in advance...

- That code means bad contents on root partition of disks.
LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by an 1s 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
You could have a number of problems.
Do you have a duo v1 or v2, see here:

Have you tried an OS reinstall via the boot menu?
I would first power down, remove and test the disks using vendor tools. Label the disks according to slot number. When you reinsert them, do so with the power off.
Do you have a backup of the data?
What firmware was running?
Did you have ssh enabled, if so can you ssh in? - Thanks for the reply. I've just edited my original post before realising your reply was there - the error code I originally described, and which your reply addresses, is when one disk (disk 2) is removed. When both disks are in, I get a pulsing power LED - four pulses followed by a single blink of the Act (activity? LED). No other LEDs blink.
The ReadyNAS is a Duo v1, bought May 2010. I tried earlier to do an OS reinstall (by holding down the reset switch with a paperclip for three seconds on power up, right?), but it did not appear to enter into reinstall mode, instead just booting as normal (if normal is the blinking LEDs I describe above!)
I'll have to hunt out my hard disk caddy from the garage in order to test the disks with vendor tools - a job for the weekend. In the meantime, to answer your other questions, yes I do fortunately have most of the data backed up (phew!); I can't recall which firmware is running, although I've tended to update it fairly regularly. AndI don't think ssh was enabled...
Thanks again. - Ok.
Which disk was reporting errors? The one you removed?
What errors were reported?
Test both disks using vendor tools - use the long or extended test.
I would first sort out the faulty disk, do you have a spare?
