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.
