Apologies if this has been covered elsewhere, I have read a LOT of posts on this issue and tried a lot of fixes and have concluded that I'm out of luck.. but… maybe someone can help me.
I have a bricked WD My Book Live 1 disc 1 TB NAS, which was failing with a green light and then a blue light permanently on, with no network access (web or ssh). I tried resetting it, nothing worked.
So I took the disc and mounted it on a SATA port in Windows trying to use SysInternal’s Linux Reader, which resulted in nothing. Windows seems to just see the disc as empty if it can see it all. Linux Reader sees nothing, just the presence of the physical disc, no partitions. Some people seem to have recovered their data at this point… but not me.
In Linux I've tried the debrick.sh script, but it fails with an error saying can't write to /dev/sd1 etc or to /dev/md0, I presume the script should be recreating these partitions but it isn't able to.
Accessing the disc in other Linux programs be it gparted, testdisc, sfdisk, fsck etc just results in read errors. Linux can see it as /dev/sdb but there are no partitions, so the majority of the low level Linux fixes I’ve read about just don’t work. I've tried data recovery in testdisc, but it results in nothing as there are no partitions.
I know there should be 4 partitions (2 raid system partitions, swap and data), I know WD are using an odd blocksize (16k), I know it's ext3 for the first two and ext4 for the data partition and I know that there should be a software raid device created for the two system partitions, usually called md0 (XFS format) that can be created with mdadm (this is what debrick.sh should be doing, but can't, as it’s failing to create the other partitions).
My question is:
- Is it worth persisting with data recovery in a program like Rescue Linux (rlinux). I could do a sector by sector scan, but this looks like it will take forever and I’m not sure if I need to change the blocksize from 4k to 16k for this to work? Has anyone even ever managed to restore data from the data partition like this?
- Do I need to enable 16k blocksize support in the Linux kernel (recompile?) for any of these fixes / recoveries to work now?
Sorry for the long post and lack of specific output errors etc, I’m just hoping someone can help me get the data of this oddly designed NAS drive or tell me that it’s probably a lost cause.
All replies greatly appreciated!
