I have contacted Buffalo Help line on number of occasions but my LS is still in EM mode no matter what I do.
(Have tried TFTP - that does not work if I hold Function button on boot up , then flash using Debug options, but now comes up with msg.
"LinkStation has booted in emergency mode. Updating may have failed. Reboot the LinkSatation.")

So I have taken out the WD20EARS-00MVWB0 drive and put in the caddy connected to my Debian Wheezy.

I have backed up all the files from /dev/sdc6 partition, where the data are.

Before when I checked in Disk Utility 3.0.2 that comes with Wheezy that /dev/sdc1 was not clean,
so I used GParted so check the partition, now it says it's clean.

I am not sure if this is how it is suppose to be, but here is the state of partitions:

Disk Utility 3.0.2:
/dev/sdc1 1.0 HB ext3
/dev/sdc2 5.1 GB Unknown
/dev/sdc3 1.0 MB Unknown
/dev/sdc4 1.0 MB Unknown
/dev/sdc5 1.0 GB Swap Space
/dev/sdc6 2.0 TB xfs


GParted:
/dev/sdc1 ext3 977.00 MiB 304.90 MiB Used 672.10 MiB Unused
/dev/sdc2 Unknown 4.77 GiB
/dev/sdc3 Unknown 1.00 MiB
/dev/sdc4 Unknown 1.00 MiB
/dev/sdc5 linux-swap 977.00 MiB
/dev/sdc6 2.0 TB xfs 1.81 TiB 1.45 TiB Used 364.22 GiB Unused
unallocated unalocated 7.82 GiB

with sdc2,3,4 showing as Unknown, is it correct?
And, why is there 7.82 GiB space unused as well on that drive?


I have even tried Rebuild partition table when updating, but with same msg.
"LinkStation has booted in emergency mode. Updating may have failed. Reboot the LinkSatation."


Should I delete all the partitions and start with:
TFTP (holding Function button on start up never worked for me:(
and then load 1.65 via LSUpdater?

I have successfully extracted from 1.65:
initrd.img (YvSInIQopeipx66t_DCdfEvfP47qeVPhNhAuSYmA4) = initrd.buffalo Size=9790226
and
uImage.img (aAhvlM1Yp7_2VSm6BhgkmTOrCN1JyE0C5Q6cB3oBB) = uImage.buffalo Size=2664296

Seems as if your second partition screwed up somehow.
The partition layout looks right, but both first and second
partition should be ext2/3.
Partition two contains the user land. Without user land, the
box will not function properly.

I have formatted the drive tried to TFTP (that worked when no partitions)
but get stuck with error the same error:
"LinkStation has booted in emergency mode. Updating may have failed. Reboot the LinkSatation."

so have run a tests:

Test Option:
EXTENDED TEST
Model Number:WDC WD20EARS-00MVWB0
Unit Serial Number:WD-WMAZA2345678
Firmware Number:51.0AB51
Capacity:2000.40 GB
SMART Status:PASS
Test Result:FAIL
Test Error Code:08-Too many bad sectors detected.


So I tried:
Test Option: WRITE ZEROS
Model Number: WDC WD20EARS-00MVWB0
Unit Serial Number: WD-WMAZA2345678
Firmware Number: 51.0AB51
Capacity: 2000.40 GB
SMART Status: PASS
Test Result: COMPLETE


And then again:
Test Option: EXTENDED TEST
Model Number: WDC WD20EARS-00MVWB0
Unit Serial Number: WD-WMAZA2345678
Firmware Number: 51.0AB51
Capacity: 2000.40 GB
SMART Status: PASS
Test Result: FAIL
Test Error Code: 08-


So it looks like the HDD has got some bad sectors.

I have tried as well:

# ./HDSentinel
Hard Disk Sentinel for LINUX console 0.08 (c) 2008-2011 info@hdsentinel.com
Start with -r [reportfile] to save data to report, -h for help

Examining hard disk configuration ...

HDD Device 2: /dev/sdc
HDD Model ID : WDC WD20EARS-00MVWB0
HDD Serial No: WD-WMAZA2345678
HDD Revision : 51.0AB51
HDD Size : 1907729 MB
Interface : Oxford/SAT USB/ATA
Temperature : 22 °C
Highest Temp.: 51 °C
Health : 11 %
Performance : 100 %
Power on time: 715 days, 17 hours

Can this HDD be saved or used for something else of should I throw it away (warranty finished month ago :) on the drive ....
What replacement HDD would you recommend?
Does it have to be WD Green Drive?

A disk with SMART result "too many bad sectors", I would
never ever use for anything else but a door-stopper. ;-)
I would recommend WD Red for NAS boxes, or any other
disk type designed to run 24/7.

so my original HDD (2TB WD Caviar Green) from NAS was at its end of life,
I purchased 3TB WD Red NAS Hard Drive from Amazon as recommended here.

As per the post over here, I have checked on my Linux machine that the drive
is unformatted before plug-in it into the LS-CHL-v2.

- - then I connected the NAS directly via ethernet cable with my PC and set the:
IP to 192.168.11.1, Subnet mask to 255.255.255.0



- - started TFTP-Boot-Recovery (TFTP Boot.exe):
from https://drive.google.com/folderview?id= ... aring#list
TFTP Boot Recovery LS-CHL 1.06.exe

Preparing to write TFTP configuration settings.
TFTP Configuration settings have been written.
TFTP Server Multithreaded Version 1.4 Windows Built 1.400


Starting TFTP...
alias / is mapped to a:\LinkStation - LS-CHL(LS-CHL8B3)\TFTP-Boot-Recovery\

defult blksize: 512
default interval: 3

thread pool size: 1

accepting requests..


- - powered ON the unit, when the Status LED started flashing Red/Orange, pressed FUNCTION button on the front of the unit


- - the 2 files have been fetched: (uImage.buffalo, 4133 Blocks Served and initrd.buffalo, 13779 Blocks Served):

-- now the Status LED light flashes fast blue (it's been like this for a while at least 2 hours) and when I pull the switch at the back to OFF,
nothing happens, the Status LED still flashes fast blue light, the fan is still ON, again it's been like this for 15 minutes.


- Is it save to unplug the Power cable?
- At which stage the partitioning of the drive will happen and how long should take it for 3TB drive?
- If so what should be the next step? Should I repeat the TFTP or move on to LSUpdater.exe
