I've been trying to post in this forum but it's been impossible from start to finish. First the country selector on the register page doesn't work. Then I couldn't post a topic because a small empty box keeps appearing asking me to select a topic. There are no topics to select, have tried 3 different browsers. Finally, somehow I ended up here. It says "select location" (category?) , but there is no category for NAS boxes. So I've just had to add it in here under "new readynas users".--- I'm experiencing these sos light signal when trying to boot up the device. I've tried formatting the drives I have in a multitude of different ways, but it will happen even when there are no drives installed. I've triedWaiting for a day but it just keeps on going.Reading the instructions, but I could not see any mention of this particular light signal.Using RAIDAR to get an idea of what is going on. It didn't provide much useful information.I tried unformatted drives, and also fat32 and exfat. The drives always worked with it prior to formatting.The OS was already factor reset and all data shredded, so there is no need to protect any data, I just need to fix the nas. You can watch the video here:

Here's an old thread on the pattern. According to this, you have "bad contents on root partition of disks" https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Readynas-Duo-flashing-all-indicators-2-long-3-short/td-p/1901087 and, you have a Readynas Duo V1 not V2. Note it doesn't say V2 on the front panel.

Correct. user8273487 has the original Duo that runs 4.1.x firmware Note that when you booted up diskless you should have seen a slightly different pattern - two slow blinks instead of three. 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 There are a couple of causes here, but the most likely is a failed disk. The system normally boots from disk 1. So maybe try removing that disk and booting with only disk 2 installed (keeping it in slot 2) and see if that makes any difference. You can also try testing the two disks in a Windows PC using vendor tools. (WD's dashboard software for Western Digital, Seagate's Seatools software for Seagate). Best options for replacement are the 2 TB WD Red Plus or the 2 TB Seagate Ironwolf. Avoid the WD Red models - these are SMR, which don't work well with NAS. Also avoid desktop drives - almost all of them in this size range are also SMR. Do yo have data you need to off-load?

Did you try booting up the NAS without disk 1 (keeping slot 2 empty). It's possible that the root partition on disk 2 is ok (the NAS normally will try to boot from disk 1). Do you have a backup of the data on the NAS? If not, you need to off-load (recover) anything you care about before proceding further. user8273487 wrote: The link posted above says "test the disks with vendor tools." , which tools?

Are you sure it isn't doing 2 slow blinks without the disks??? user8273487 wrote: The nas says "RND2000 v2" on the back, that's why I put it down as a v2. The labeling is quite confusing - I think if Netgear had a do-over they would have branded both the Duo v2 and the NV+ v2 differently. user8273487 wrote: What I would like to ask is, what format does it want the disks to be in for a new installation? The NAS needs to format the disks, and it will create the root partition and install linux and the NAS application software on it. You can either boot up with formatted disks or you can do a factory default using the boot menu. Pages 15-16 here give you more info on the boot menu options: https://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf

If you formatted the drives on a PC as GPT and it created a "protective system partition", your NAS cannot delete that. Diskpart from a Windows command line will allow you to delete it. Alternately, do a quick erase with the same vendor tools StephenB is recommending for testing the drive. What the NAS wants is drives that are completely unformatted. The error message is saying that there is one that it can't read.

Generally I run the full vendor diags on a PC before I install new disks in the NAS. With Seatools, that includes the full read test and the full write-zeros test. Unfortunately WD's dashboard software doesn't include the write-zeros test. Which tilts me a bit towards Seagate drives. Some of my out-of-the-box disks have passed the read test, but failed the write test (and in some cases they've failed the read test but passed the write test). As I said above, avoid SMR drives, and make sure your disks are no larger than 2 TB.

    Thanks for the information. So 3 slow blinks = "Bad contents on root partition of disks", but it does it even without disks being present.
    
    What I would like to ask is, what format does it want the disks to be in for a new installation? Bad contents on root partition suggests that it wants a root partition, but I'm not sure how to create one of those or how to set up the drives for its needs.
    
    P.s. The nas says "RND2000 v2" on the back, that's why I put it down as a v2. It also says "NGR-RND2000 (B)" and "272-10635-02".
    
    The link posted above says "test the disks with vendor tools." , which tools?
