Buffalo Forums

I have a CS-WV20/1D NAS device that has been running for years.
Thursday I was told it was taking a minute to open or close a 1 page Word Document. I told my wife to reboot the NAS and I would check on it when I got home.   The unit went offline.  I google the flashing red lights and discover NAS Navigator.  NAS Navigator finds the unit and reports it is in EM mode.

I call Buffalo Tech.

They suggest I flash the bios. The flash fails.

I call Buffalo Tech.

They tell me the new blinking red light code indicates too many bad sectors on the hard drive and I have a corrupted firmware.  I am sending the drive out for data recovery, since we have not gotten the files to sync to the cloud... (Another case with Buffalo) I am told we will need a new drive.  I go out and buy a new 1Tb "NAS" drive and install it in case.  I turn on the power and I get the red LED blinking 6 times.  I google NAS TFTP recovery and panic. 

I call Buffalo Tech.

They tell me they cannot support me with adding a new drive, they suggest I try their forums...
I take a deep breath and google NAS TFTP recovery again...

I disable my PC firewall and antivirus software.
I make a recovery directory: C:\Users\742591\Downloads\NAS\CSWV_Firmware
I put these files in it:
hddrootfs.img
initrd.img
linkstation_version.txt
LSUpdater.exe
LSUpdater.ini
u-boot.img
uImage.img

I edit LSUpdater.ini:
[Application]
Title = BUFFALO CloudStor Series Updater Ver.1.13
WaitReboot = 1200
WaitFormat = 600
WaitFileSend = 600
WaitDiscover = 120

[Target]
ProductID = 0x00003009
ProductID2 = 0x0000300A
ProductID3 = 0x0000002A
Name = LinkStation

[Flags]
VersionCheck = 1
NoFormatting = 1

[specialflags]

Linkstation_version.txt:
VERSION=1.13-2.35
BOOT=
KERNEL=
INITRD=2012/02/20 17:53:40
ROOTFS=2012/02/20 17:58:36
FILE_BOOT = u-boot.img
FILE_KERNEL = uImage.img
FILE_INITRD = initrd.img
FILE_ROOTFS = hddrootfs.img

Neither NAV Navagator or LSUpdater see the CloudStor.
I load Solar Winds TFTP server and made its home directory: C:\Users\742591\Downloads\NAS\CSWV_Firmware
I static address my workstation to 192.168.11.1.
I start my TFTP server.
I can ping my server at 192.168.11.1.  I do not get a ping response from 192.168.11.50.
I power cycle the NAS.  The blue light flashes for about 20-30 seconds and then goes out.  Within 5 seconds the red led starts blinking six times.
Repeat the power cycle, same results.
I use a cat5 cable to hook the NAS directly to the PC and power cycle the NAS.  Same results.
The ping of 192.168.11.50 never returns a ping response.

Now what?

So.. you can try this. this is for another bay version of the cloudstor with different hardware but same firmware version.

or this

^this is for the linkstation, to be honest there are no real differences i can see with the cs-wvl and the ls-wvl besides firmware and the sticker on the front lol

if you want to try solar you can use this as a tut just change the unit really
