mount_block_root +25e Help - any ideas how to fix this
Help - Can't get into boot menu or do anything with my ReadyNAS RN31400. Had a ower cut and the above error appeared.
Nothing working - can't get into BOOT Menu using the reset button, or boot from USB. Any help much appreciated.
Thanks John

I suggest powering down the NAS, and removing all the disks (labeling by slot). Then boot up the NAS, and see if the NAS boots normally (giving a "no disks" status), or if you still see the mount_block_root +25e error.
If you still do see it, then there was some damage to the chassis (likely the flash) when the power was cut. The warranty is 5 years, so you might want to check if you are still covered.
JohnTemple Did you try this solution? Did it work?
I removed all six drives, powered up and still see the message "mount_block_root +25e"
Is there a way to repair the unit?
If not, do I have options for recovering the data that is stored across those 6 drives?
- Hey guys!
I’ve got the same error message on my NAS after a power cut to. Has anyone managed to fix this issue yet? I’m still having issues creating a recovery usb stick, in the firmware version drop down box there is nothing to select & so won’t do anything. I have tried 5 different usb sticks. Please help!

Please help!It sounds like you skipped a step. you need to do step 5 if you don't move the img file into the right firware folder when you try to run it, it don't know what img to use. Hope this helps you because my ReadyNAS is still broken. :(
- Download the USB Recovery Tool.
- Extract os6-recovery-tool.zip to a new folder on your desktop.
- Download the latest firmware package for your ReadyNAS model:
- Visit ReadyNAS OS 6 Support.
- If you're using a ReadyNAS 100, 200, 210, or 2120 series model, download the ARM firmware package.
- If you're using any other ReadyNAS series, download the x86 package.
- Extract the firmware file (.img) and release notes from the zip file to the same folder you used for the USB Recovery Tool.
- Open the Recovery Tool folder on your desktop and move the firmware file into it:
- If the ReadyNAS is an RN100 or RN2120 series model, move the firmware file into the Arm folder.
- If the ReadyNAS is a 200 or 210 series model, move the firmware file into the rn2xx folder.
- If the ReadyNAS is a 310, 420, 510, 520, 620, 710, 3130/3138, 3220, 3312, 4220, or 4300 series model, move the firmware file into the x86 folder.
- Hey Mfisch23!
If it wasn’t for this virus going round I would reach through the internet & give you a massive kiss!!! You are a star! Thank you for pointing out what seems really obvious now! I managed to make a boot drive & on my second attempt it worked! My NAS is now working again, thanks to you! Give yourself a treat tonight! Thank you so much!
Sorry to hear yours is still out of action. I’m not sure if you’ve tried this but when mine came up with Boot From USB drive on the display I pressed OK rather than waiting. Worth a go if you haven’t tried, also like Sandshark suggested try with a stick with a LED on so at least you know if something is happening. For reference mine took less than 5 minutes to reinstall OS.
I hope you find the solution to your issue quickly, it’s a pain when it goes down. Once again, thank you for your help!
I had this same problem and i was trying to reload software on multiple usb drives and nothing was working. Then while searching on the netgear community for a solution, someone mentioned to run the USB software as administrator. So, I plugged in my USB drive right clicked the usb exe file and clicked on run as administrator and reformatted drive. I reinstalled the recovery software on the same usb drive and tried loading from usb and it worked. Im not sure if running as administrator made a difference but as soon as I did that nas was able to recover from usb. Hopefully this works for anyone with the same issues.
Just as "MCJCALVI80" said.
I tried 6 different USB's, then I tried running the USBrecovery tool one last time, this time I right-clicked the file and ran the file as administrator. Formatted the USB-drive with the USBrecovery tools built-in format function and then created the boot... Finally worked like a charm!
+1 for USB format... right click the usbrecoverytool.exe and choose "run as administrator" and then the recovery worked first time on RN314, after several failed attempts without doing this. process takes 60 seconds or so.
I have mine on a APC and we lost power so I went to manually turn it off. Went to turn it back on after power was restored and getting this error. I tried 2 flash drives to no avail yet. I tried in both back ports and the front port. Turned power on, waited for the ring to turn off, held the OK till it showed Booting off USB, then release. Am I missing something?
Of course my warranty ended 2 months ago :-( Does it pay to contact Netgear since this issue is impacting numerous users?
I could definitely recommend NOT to use Netgear support for this.
The process is fairly straight forward.
All they did recommend a process which I aleady knew about.
I contacted them becuase I thought they might be interested in getting further metrics from the field about a potrential bug in their firmware. But they were more interested in whether I had a support contract than actually helping.
So I ran the recommended process without any problems whatsaoever.
Obvisously YMMV.
All the best
(I will point out, that any credible/goof vendor would still help you with such a problem if you warranty has expired by just 2 years.)
I removed my storage disks from slots (just don't want to loss any data) and now i am doing usb recovery tool.
NAS was saying that " boot from external drive" from last 15 mins
how much time it will take to finish?
IS it working or not?
- It shouldn’t take very long, perhaps a minute or two and then the system should power off.
You could try booting without the USB connected. If it has worked then you won’t get the mount_block_root error anymore.
If it’s still stuck on booting off USB after 15 minutes that would suggest either an incompatible USB key, or that the steps to create a USB Boot Recovery key were not followed correctly.
Perhaps try a different USB key.- Read the earlier notes about copying the data onto the usb stick as Windows administrator. My install kept failing until I did this and then it ran successfully the first time after.
thank you so much.
All of you saved me
Third USB drive worked.
- Hi
Can anyone list what usb stick worked please. Mines been like this since 1st lock down :(There are so many different USB keys out there.
Make sure you run usbrecovery.exe as Administrator.
An older USB key maybe is probably more likely to work.
Which model ReadyNAS do you have and where do you get stuck in the process?
What happens when you try to boot off USB?
