Readynas Pro 6 won't boot
Hi, Since years I am a happy ReadyNas Pro 6 owner. Half a year ago I upgraded the ReadyNas Pro 6 to Readynas OS6. It worked just fine and fast! A month ago I stared to have some disk problem...

Thanks to the great help of mdgm my Readynas Pro 6 is running the lastest Readynas OS6 again!
I ended up using dd on a debian life boot disk to dd flash the image mdgm supplied to me back to the internal flash.
After that I mounted the partition and copied the supplied serial number file to the internal flash.
Mdgm, thanks for you great support!
Kind regards,
Michel

I have tried all available USB recovery images. They won't work on my machine.
What I see on the console is:
And then simply nothing happens :(
I have booted from a Debian live USB and noticed that the MBR on the internal 128MB USB memory is corrupt.
What I need is a RAW image of the internal 128MB USB so I can restore it inclusing the MBR.
Is someone willing and able to make a dd image of the internal flash?
All you need to safely do that is ssh root access to your Readynas Pro 6.
If you ssh into your readynas, first figure out the path to one of your shares.
Let's say you cd to your share at:
/data/myshare
Then enter the following command:
fdisk -l | grep 128
This will show you a 128MB USB device. Most probably /dev/sda
Then enter:
dd if=/dev/sda of=/data/myshare/usb.img bs=512k conv=noerror,sync
This will make a RAW image of your internal flash and store it on your share.
If you could zip that and send this to me somehow, I would be eternally thankfull!
Cheers,
Michel

But wouldn't that also include the serial number, efffectively cloning my Pro to yours for ReadyCloud and such?

I'm not 100% sure, but it would be quit silly if Netgear would have stored it on flash.
I presume it is stored in the hardware (bios or eeprom or something like that).

Maybe best to wait for mdgm or another Netgear person on this.

We store the serial number and other EEPROM data on the internal flash on legacy x86 and ARM ReadyNAS. I have replied to your PM.
Also USB Boot Recovery formats the USB key. If I recall correctly it puts a new MBR on it, so it's a bit surprising it didn't work.
