An attempt to make it easy to debrick, and possibly manage, a WD MyBook Live NAS.
Pretty much everything comes from various online sources which may not be there forever, hence this repository.
The script is intended to be executed as root.
So far, I have only tested – with success – the os-recovery command. Right now its --help is quite poor, have a look at the source.
In order to restore the OS, you have to retrieve the apnc-xxxxxx-zzz-yyyymmdd.deb firmware's file. The script wants the *.img archived inside.
Note to self: I have several such files on an external hard disk.
I suggest to restore a previous version and then upgrade to the last one with the NAS interface (should we miss something not mandatory in the process).
There are some utilities and useful informations (as comments) inside the script; e.g. for retrieve files from the DataVolume when partially-bricked and mounted to another host machine (hint: it uses debugfs).
I used a spare Ubuntu virtual-machine to perform the debrick process; I don't remember, but I suppose that I may have needed to perform the following commands:
sudo apt-get update
sudo apt install gddrescue
sudo apt-get install mdadm
sudo apt install gcc
sudo apt install smartmontool
sudo apt install pv
If the NAS is partially working, before running the script it may be necessary to stop the RAID array:
sudo mdadm --manage --stop /dev/md0 -f
In case of new disk with bad sectors, the following may be useful:
# maybe try with also the `-y` flag
sudo ddrescue /dev/zero /dev/sdb -f -D -v
sudo dd if=/dev/zero bs=1M | pv -p -e -r -s 2T | sudo dd of=/dev/sdb bs=1M
# Prints the SMART information about the disk:
smartctl -a /dev/sdb
