Dear All, In desperate need of some help! Setup:My ReadyNAS Model Name: RNDP200U (Model No: RND-2A) is not reading the two disks.Using Raidar 4.3.0.X-Raid2 Setup - I believe as I did not go into any complex setup procedure. It would work with one disk in and hot swapable, without issue in the past. I would take one of the disk on holiday for security.Disks 2 x 3TB Seagate Barracuda XT Symptoms:1. Raidar finds the NAS (See Attached) dut does not detect disks. 2. I cannot connect to it via the web interface, I get a time out error after a short while. 3. Prior to failure, the disks in Raidar were shown as green(No faults). So I am assuming the disks are ok? 4. I initially suspected a fan or power supply issue, as the LED on the power supply was flickering as I disk were inserted and there was a odd noise (cycling) as the disks tried to spin I assume. This noise was the original symptom before failure. I thought it might have been the fan so cleaned the fan and cabinet. The power supply was changed with a new one. 5. The NAS itself cannot be shut down by double clicking on the power button as usual. I feel like it is not booting up properly? Could it be a failed DIMM memory? 6. I have tried another spare disk in the NAS, but does not do anything with it! Not seen by Raidar Solutions & Questions?1. I have ordered a similar NAS off ebay; RND2000v2. If I plug the old drives in the new NAS, will it work? Or will it erase the data? 2. Thought of getting a 8TB Seagate drive for my computer to clone copy the data off the two 3TB drives via Macrium Reflect as a backup on to two partitions, before inserting the disk into the new NAS? Any thoughts? 3. Anyone have experience of power supply issues which damages the NAS? I would really appreicate your help on this. Hoping I can save a lot of Data! Thanks in advance for your help :(

Just to verify that you installed just the spare drive, correct? If so, and the drive you used is known to be good, then this is an indication that the NAS chassis has a problem. That depends on whether the disk was already formatted (unless a factory default was done via the boot menu). Though RAIDar should have seen a "corrupt root" in that case. Anyway, I still think it is worth circling back to this after AmalW has the data off.

I once had a similar problem with the exact same drive type in an NVX. I attributed it to a mix of drive types since I had three Seagates that came with it and one Hitachi I added, though all were 7200RPM enterprise grade drives, But maybe it was just the drives themselves or the chassis. Seemingly randomly at power-on, or drive spin-up when spin-down was enabled, one or more of the Seagates (never the Hitachi) would show as dead, though they clearly could not be if it was more than one. Another power cycle or reset would not clear it. The only solution to "resurrect" the drive to was to hot remove and re-insert the drive and let it re-sync (one at a time if more than one was involved), though that was really only necessary if I wanted good drive diagnostic data since everythinhg else worked fine. Even a backup, factory default, and restore did not fix it. My interim solution was to turn off drive spin-down since I rarely power cycled, but it did not cure it, it just gave it fewer opportunities for it to happen (I know this because it happened on a subsequent OS update). I ended up moving to OS6, which the NVX cannot run, so I moved them to a Pro6 converted to OS6 and the problem went away, even after adding two more Hitachi's. So, I don't know if the different chassis or OS6 made the difference. That NVX was never used again. I stole the backplane from it to fix an Ultra4. I was not yet adept enough at Linux to go in and look "under the hood" at what was going on at the Linux level, that's all the information I have. Though you replaced the power supply, there could have been secondary damage to the chassis if the input voltage spiked too high during the failure, so trying the other chassis might help. Unfortunately, both my experience and yours is that once the drives are marked dead, it seems a power cycle won't clear that, and so a chassis change probably won't either. You'll have to do as I did: Remove one drive with power on, wait till the NAS recognizes that, then re-insert and let it re-sync. I'm pretty sure I didn't end up having to zero the drive with a PC in between since OS4.x doesn't check for a previous OS on the drive before formatting. Obviously, your backup should be up to date when trying this, as two syncs are an opportunity for those older drives to fail. As I believe was mentioned earlier in the thread, you should insure the OS version on the new NAS is the same as your old. And testing each bay by swapping the scratch drive you use for that process between bays with power off, then powering on, will do that. Or, bite the bullet now and move to OS6 on either chassis. I believe you'll find many other enhancements to you liking. If you are going with larger drives anyway, Thios is a perfect opportunity, Use them in the conversion process of one chassis, then copy the data from one to the other.

AmalW wrote: I thought I would try to update the firmware to OS6. But I could not find anywhere to upgrade to OS6 on the ReadyNAS Frontview web admin page under updates? Any tricks? You certainly won't find it there, as Netgear doesn't support the conversion. The steps are: (Optionally) make sure the latest BIOS is installed before you do the conversion. To do this you install http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin as an add-on and reboot the NAS. Do this after you backup the NAS. This isn't necessary, but if you do want to update the bios it is easiest to do it prior to conversion Basic instructions for the conversion itself are BACKUP, BACKUP, BACKUP Upload PREPR4TOR6_0.1-x86.bin as an add-on using the ReadyNAS web gui, but do not reboot afterwards (avoids the need to do manual factory resets) Upload R4toR6_6.9.5.bin using the ReadyNAS web gui firmware update After you upload the addon+firmware and reboot, it will update the firmware and start a factory default. Go through the setup process on the converted NAS Update the NAS to the current OS 6 (check for updates will work). Restore files from the backup. Netgear won't provide paid support on a converted NAS, so that is one consideration. There is a small risk that the process could fail, and if that were to happen it might not be possible to get the NAS running again. AmalW wrote: Also noted that the the latest Ultra 2 I bought as spare is an Ultra 2, whereas my original RedayNAS is an Ultra2 Plus. What is the diference? The ultra-2 uses a different processor, and is quite a bit slower. No idea why the memory didn't work though.

It will not work - the nas either won't boot, or it will erase the data. If you do need to off-load the data, you can connect one of the disks to a Windows PC (via SATA or a USB adapter/dock), and use R-linux for Windows to access the files. https://www.r-studio.com/free-linux-recovery/ AmalW wrote: there was a odd noise (cycling) as the disks tried to spin I assume.

Stephen,Many thanks for you message.Ok so if will be damage limitation to recover data. Disaster if I cannot!Is Seatools from Seagate I presume? Do I do that first or the linux recovery?Thanks again

  Stephen,
  
  Many thanks for you message.

  Is Seatools from Seagate I presume? Do I do that first or the linux recovery?
  
  Thanks again

    I'd run the quick Seatools test first (it normally only takes 1-2 minutes). Both drives should be mirrored, so if one passes, you should be able to recover from it.
    
    Note you will need storage to copy the files onto (for instance a USB drive). R-linux doesn't repair anything, it just gives you access to the files.

Since you had no luck with (I am assuming a known good) scratch drive, then the likely problems are a bad SATA subsystem and a bad internal power subsystem (converts the power brick 12V to the required internal voltages). Neither of those is repairable.

Unfortunately, the NAS you chose to purchase is very much not like your old one. It has a different processor and runs a different version of the OS. Compatible desktop units would be the Ultra2, Ultra2Plus (which is what you have), Pro2, Ultra4, Ultra4Plus, Pro4, Ultra6, Ultra6Plus, Pro6, ProBE, and Pro Pioneer. The NVX is also compatible, but not really a good choice because of it's 32-bit archetecture. There are also some rack-mount models. Many of those for sale have already been converted to run OS6, so you'd have to re-convert back to OS4.2.31 to mount your volume, assumning it's still intact and not damaged by whatever took out the NAS chassis.

Moving forward with recovery outside the NAS is probably your best choice.

  Might be worth revisiting that after AmalW recovers the data. I'm not clear on exactly what was done with the scratch drive.

    Sandshark/ Stephen,
    
    I have not done anything with the two original drives, except for taking them out and putting them back in the NAS.
    
    By scratch disk do you mean one of the two originals? Is it likely that both disks would fail at the same time?
    
    If it is a hard disk mechanical fault , sre there people who can repair them in the UK?
    
    I am expecting the the back up USb & internal Seagate 8Tb drives to arrive late today so I can start to recover?
    
    All your advise appreciated. Thanks

  Hi Sandshark,
  
  The compatible drives you mention in your response; If I get one of those you listed, would that be plug and play without risk of disk erasure?
  
  "Compatible desktop units would be the Ultra2, Ultra2Plus (which is what you have), Pro2, Ultra4, Ultra4Plus, Pro4, Ultra6, Ultra6Plus, Pro6, ProBE, and Pro Pioneer."
  
  Is there any harm in running the Seatools utility on the disk first as suggested by Stephen?
  
  Thanks Amal

This is what I meant by you having no luck with a scratch drive. Just to verify that you installed just the spare drive, correct? If so, and the drive you used is known to be good, then this is an indication that the NAS chassis has a problem.

You asked if there was any repair shop, and I already answered that the possible causes are not repairable. Netgear has never provided NAS repair services except under warranty and has not provided schematics or parts for any third parties.

  Sandshark/Stephen,
  
  Thanks for your message. I thought if I put in another unrelated drive and it did not recogise it, it would format and start up. It did not.
  
  I have made some progress though finally!
  
  Disk1 - Tests
  Disk Info ok.
  Short Generic Test - 100% pass
  Short Disk Self Test - 100%
  It did make a few odd noises on start up but tests ok :)
  
  Disk 2 - Waiting for Seatools! It is being a dog again! "USB: Scanning for supported drives. Please Wait..."
  Disk2 seems to be spinning ok though; no noises!
  
  8TB Backup USB drive arrived from Amazon!

  I was asking if the hard disk could be repaired. I know there are data specialists who rebuild drives to extract data?

    Still waiting for Seatools to startup to check DISK2!
    Restarted and plugged & unplugged several times!!!
    
    Stuck on;
    "USB: Scanning for supported drives. Please wait..."
    
    I would have thought that Seagate would have some decent software tools! Been using Seagate drives for 20+ years in PC's & Macs!
