MBL 2To data gone but here

For some unknown reasons I lost years of video archive on my MBL yesterday.
The setup:
Synology NAS mapped to shared folders on the MBL:
/Movie/MovieMBL(mapped network shared called Videos)

GNU Parted 2.2
Using /dev/sda

I first checked as previous posts like @TonyPh12345 suggested 3TB MyBookLive is holding all my data hostage

I tried “fsck -y /dev/sda4” -y for auto fix. It founds a lot of error:
"/dev/sda4 contains a file system with errors, check forced.

Then I restarted it:
MyBookLive:~# reboot

I recheck the login messages:
MyBookLive:~# dmesg | tail

From my Synogoly the folder seems mapped but empty, I unmount on the NAS the share from MBL try to remount same: can mount but empty.
I tried to mount on my mac with smb or afp or ftp, it mounts but when tried to browse content it disconnects.

I tried to create a demo shared folder on MBL and mapped on the NAS and my Mac, and put a sample file it works and accessible.

I unmount the required shares again then run:
MyBookLive:~# fsck.ext4 /dev/sda4
e2fsck 1.41.12 (17-May-2010)
/dev/sda4: clean, 37964/30355200 files, 20830057/30453104 blocks

That made me think that the MBL is working “properly” but my previous shared show no size in the web interface of the MBL 0 out of 2 To.
I thought the data where gone, but not:
MyBookLive:~# df -h

/dev/sda4 1.9T 1.3T 588G 69% /DataVolume

As you can see the datas are here because 1.3T is used. I start to get lost so:
ls /DataVolume/lost+found/

From there I have no ideas what do to recovers years of videos archive.

Any help or suggestions would be so much appreciated.


I have not try this setup yet. Let’s see if any of the users can share some information about it.

Above all even the diagnostic tools can’t be run and asked to contact the support after few seconds. Getting very disappointed!

Got contacted by support: long story short warranty expired but the MBL works, data are here but can’t access them.


Do not have much to say. However, if you know any Linux Gurus, they might be able to help.
These boxes run Debian Lenny.

In case you have to take out the drive to connect it to another PC via USB:

  • Win/Mac will need an app to see Linux partitions
  • Linux machine should be able to mount drives just fine. You can also use a Linux Live CD.

To take out drive see here:

And last, in the future, do not forget the importance of backups.
I personally went thru the same years ago, ever since, 2+ copies of important files at different media/server/PCs/etc.

Thanks but basically the MBL “works” when I create new shares, that maybe my last option unless I find a recovery option.

Thanks for the hint!
