Hi,

I bricked my LSmini I'm now trying to recover the data, it is driving me nuts.

is this the right place to post such question, I don't know, let me know otherwise.

I've already done a thorought investigation into the drives (dismounted, thanks to a recovery software) So far, I've only been abble to recover half of the picture there was in it. And when I say half, I'm not talking about the files, which were recovered entirely but the actual data of each pictures. Althouth the preview is good, when I open the picture I get to see only the top or the bottom...

my LS is flashing red 6 times, normaly it's a HD problem. what is the best solution for me to recover my pictures ?
Given my LS mini was in raid 0 do you think it is worth trying to revover the data or is it lost forever ?

If yes, here are my options, what do you think of it ?

1. Perform another data recovery with a different software
2. Try to restore the drives drives throught Reflashing or Reinstalling Firmware
3.Throw away my brick.

Thanks for your help.

Ric

Ok I'm downloading Knoppix to see what I can do with it.

My problem is that my LS Mini don't even appear on the network nor when I plug one of the Hard Drive on a usb port (except if I use a specific data recovery software)

Assuming that the hard drives still work...

Follow this article to disassemble your device...
http://buffalo.nas-central.org/wiki/Disassemble_the_LS_MINI

Attach both drives to the SATA interface of a computer that can access the internet.

Download and burn the Ubuntu 10.04 Desktop Edition CD-ROM from here...
http://releases.ubuntu.com/lucid/ubuntu-10.04.1-desktop-i386.iso

Make sure the drives are attached to the primary and secondary SATA ports of the computer
(so Ubuntu will recognize the drives as /dev/sda and /dev/sdb).

Boot Ubuntu 10.04 Desktop Edition CD-ROM on computer.
Select language as desired (English).
Click on "Try Ubuntu 10.04 LTS" (to use Ubuntu without making any changes to your system).
Open a new terminal window (Applications | Accessories | Terminal ).

Start a new bash shell with root privileges...
Code:
sudo bash

Install the mdadm package (to administer RAID volumes)...
Code:
apt-get update
apt-get install mdadm

Attach RAID volume...
Code:
echo "y" | mdadm --create --verbose /dev/md1 --level=0 --raid-devices=2 /dev/sda2 /dev/sdb2

Mount RAID volume...
Code:
mkdir -p /mnt/lsmini
mount -t xfs /dev/md1 /mnt/lsmini

Copy files from /mnt/lsmini to your backup drive

Once you have completed the backup, try to unbrick your device by reverting to stock firmware...

:biglol:

Thank you so much I did'nt see your reply untill now.

Before trying your procedure, how can I be sure the hard drive isn't dead ?

my problem:

when I start my ls-station it stops rapidly and shows a red flash, blinking 6 times

I read somewhere this meant:

"The 6 red LED flashes can usually refer to a failed internal HDD or HDD controller."

Do you think It is worth it for me to try you procedure ?

or

Do this mean my data are lost for ever ??

Thanks

If you follow the procedure, you will discover whether or not there is a faulty drive in the device. The procedure itself should not damage the hard drives (it just tries to mount them), however follow it at your own risk. If you can successfully access and backup your data using this procedure, then the problem is likely with the device's drive controller and not with the drives themselves. The instructions assume that you have the factory default configuration for your data (which I believe is RAID0 on partition 2 formatted with the XFS). If not, then adjust the mdadm parameters accordingly.

Good luck.

Hi all, I have a LS mini in RAID that I accidentally formatted with a firmware update (the drive was stuck in EM mode but didn't have any error lights flashing). I can see the drives in disk manager in Windows and the portions are healthy (I've already removed them both from the case and attached to my windows machine.)

Could I just get to the files using rpinchbeck's instructions above? I would just like to move them to another TB drive for now. Will they be whole (for the most part)?

Or, should I continue on my current course, which is to use r-studio to do a full scan and then copy the files? If so, does anyone here know the block size and default file system for raid 0 on the mini? I don't think I ever paid attention when I got the drive, so I'm assuming it will still have the defaults.

Any other ideas? Thanks!
Michelle

I have a LinkStation DUO that was configured with RAID 0. I tried the process you detailed here and unfortunately I get the following error at the very last command:

Code:
root@ubuntu:~# echo "y" | mdadm --create --verbose /dev/md1 --level=0 --raid-devices=2 /dev/sda2 /dev/sdb2
mdadm: chunk size defaults to 512K
mdadm: /dev/sda2 appears to be part of a raid array:
    level=raid1 devices=2 ctime=Tue Nov 25 01:08:33 2008
mdadm: /dev/sdb2 appears to be part of a raid array:
    level=raid1 devices=2 ctime=Tue Nov 25 01:08:33 2008
Continue creating array? mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md1 started.
root@ubuntu:~# mkdir -p /mnt/lsmini
root@ubuntu:~# mount -t xfs /dev/md1 /mnt/lsmini
mount: wrong fs type, bad option, bad superblock on /dev/md1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


Any advice?

Thanks!

Based on the error message, I would guess the RAID volume is not formatted with XFS. The syslog might confirm the problem... did you examine the syslog like the message suggests? I don't know what the default file system is on the LinkStation Duo... try some other supported file systems like ext2, ext3, or ext4.

Hi rpinchbeck, thank you so much for taking the time to reply. I did a bit more research and I found out two key bits of information. The first one, you are right, the partition that I was trying to mount is actually ext3, but unfortunately it doesn't do me any good. The partition I need is 6 (sda6 and sdb6 - RAID 0). Unfortunately sda6 is completely missing :cry:. I went ahead and opened my own thread with all of the details.

http://forum.buffalo.nas-central.org/viewtopic.php?f=4&t=27885

If you have any ideas, I am all ears.

Thanks again.
