ReadyNAS error: "mount_block_root+1f1"
After installing the 6.7.3 firmware (6.7.1 > 6.7.3 upgrade), I'm seeing the error message "mount_block_root+1f1" on the LCD. I was going to try the USB Recovery method, but I saw in this similar thre...
USB Recovery with a variety of thumb drives, syslinux.exe versions and 6.7.3/4 didn't work on the unit that was having trouble.
Netgear sent a replacement 314, and the USB Recovery process worked great (on the first try!) for updating the firmware.
So the problem was that 6.7.3 effectively bricked my unit.
The disk needs to be syslinux bootable.
The same contents of the x86 folder that usbrecovery.exe puts on the USB key need to be put on the USB key.
Rufus should put the syslinux boot loader on the USB key itself if you chose the correct option.
If you have updated to 6.7.3 and ran into this issue please try USB Boot Recovery with ReadyNAS OS 6.7.4 which is now available!
If you have not yet upgraded please upgrade to 6.7.4 rather than 6.7.3. If your system has already been fixed I would still suggest updating to 6.7.4 the normal way using the web admin GUI.
If you can't do USB Boot Recovery despite trying multiple different USB keys and following the directions you'll need to contact support.

I just upgraded to OS version 6.7.4 and it also practically bricked my unit. Now I'm getting this error at bootup. Although the first reboot after the upgrade went fine. I will try the USB recovery method.
What's the accepted method for the USB recovery? Do we need to downgrade to before 6.7.3?

In particular, do we install the latest 6.7.5 image? I have downloaded the experimental USB recovery tool and placed the 6.7.5 image under x86/, but my when I boot my RN314, it does not go further than saying "Boot from external USB".
So is that the solution when it fails and you went through all the steps, booting to a valid, prepped, FAT32, 32gb thumb drive? Get them to send a new unit?
I ran through the posted solution (using fw 6.7.5), and it was booting to the USB drive, but never said anything about firmware. Then got same error message (mount_block_root+1f1)
I'm going to play with mine some more-- maybe try to boot to an older firmware. The original failure was after I told it to upgrade to 6.7.4...
This unit is an RN716x with 6x6tb drives (=single 27tb volume), using firmware 6.7.1 (last time it worked). Been in service for almost a year with no problems until now.
I have 3 others just like it that all went to 6.7.4 okay, plus some RR3312 (12x10tb=90tb volume) units that also upgraded to 6.7.4 just fine.

Yes, the new unit was the solution. And I think that's confirmed by the fact that the new unit carried out the USB Recovery process successfully using the same USB stick that didn't work on the old unit. Believe me, I tried every USB stick I could find and every variation of the USB Recovery software.
I have a legacy Ultra 4 that upgraded through all the 6.7.x firmware releases without incident. Still waiting to see how 6.7.5 works for others before upgrading, though — once bitten, twice shy.

Oops! Double post? I hit post once, and it said fix errors and resubmit, so I did. Didn't meant to post it twice.
OS 6.7.4 doesn't help really!
I've update the RN516 after the security Mail from Netgear from 6.7.1 and they work after the Restart.
And so I also update also the RN316 from 6.7.1 to 6.7.4.
Now after some Days are both RN bricked with "mount_block_root". :(
"USB Boot Recovery" only ends with "boot from external USB" and flashing USB-LED.
I try different USB's and one of them is located next to the RN316, because they done Recovery some time before.
You could try using Rufus to create the recovery key and/or perhaps try an experimental version of USB Boot Recovery with some improvements: https://www.readynas.com/contributed/mdgm/usbbootrecovery/usbrecovery.v2.0.R15-T3.zip
Same thing happend to me on 516. Upgrade to 6.7.1 to 6.7.4 seemed OK.
After power cycle the next day, I'm now getting:
"mount_block_root+1f1"
