I have experienced the constant network loss of the NAS from a reset occurring only after the upgrade to 1.8x firmware.

They updated U-Boot in firmware 1.80 and, I think, did not fix the core.

Old version U-boot U-Boot 2009.08-svn ( 4月 09 2013 - 19:15:41)Marvell version: 1.1.3 NQ

New version U-boot U-Boot 2011.12 (Jan 15 2015 - 21:22:47) Marvell version: v2011.12 2014_T2.0p1

If there is a log to find, I would submit it. I wish buffalo would stop telling their customers they are lying and I pray they can figure out how to replicate the issue 'in their lab'. Maybe they should try multiple heavy transfers with two four TB drives and fill the system to little over 3 TB of data. Push the system a little like the users are. It would be nice to hear from the lab as to what tests were implemented to determine how they stress the system.

All the logs were sent to them and they all know about the problem. It is better to buy Chinese ...

Striking attitude towards customers ... if you do not want to suffer, Buffalo, please, make firmware DD-WRT/OpenWRT

I have experienced the constant network loss of the NAS from a reset occurring only after the upgrade to 1.8x firmware. I would like to downgrade but there are some features in the 1.81 firmware I desire which were fixed. My drives are not failing and are four TB Reds designed for 24/7 functionality. f there is a log to find, I would submit it. I wish buffalo would stop telling their customers they are lying and I pray they can figure out how to replicate the issue 'in their lab'. Maybe they should try multiple heavy transfers with two four TB drives and fill the system to little over 3 TB of data. Push the system a little like the users are.

Storage / Factory Reset Questions
« Last post by Psychlone on August 18, 2017, 07:39:24 pm »
Hi there, new Buffalo user, local field tech for a computer repair business.

I have a customer that has an LS420D set up in a RAID1 with two 2TB drives of which one has failed.  I used Navigator 2.91 and try to get to the online settings panel but it simply won't allow it.  NASNav sees the unit and has an ip address for it, but the NAS itself doesn't show up in the box for me to right-click on to get to the actual online settings panel.

If I boot up with JUST the original good drive in, it takes about 15 minutes with white flashing power, then it turns red and blinks 7 times repeatedly.
If I boot up with JUST the failing drive in, it takes about 15 minutes with white flashing power, then it turns amber and flashes 1 long, 6 short along with Drive 1 light turning red.
If I boot up with both the known good drive and the new replacement drive in, it's 15 minutes of white flashing power followed by 7 red blinks repeatedly.
If I try to boot up in EM mode, it simply won't do it at all... just sits on white flashing power forever.
If I try to boot up with both original drives (the good AND the failed drive, just as it was when I walked into the job), it's 15 minutes of white flashing power followed by amber and then drive 1 is red.

In ANY combination, the unit does not show up in NAS NAvigator2 other than it's ip specs, firmware version and it's name down below at the bottom of the navigator window.

So what are my avenues of recovery here? 
Drive 2 is supposedly known-good, drive 1 is in failing condition.  The RAID array is obviously degraded, but I can't get anywhere without the online settings panel to do anything about it.
FWIW, I've already ordered a brand-new 500 series LS with two 4TB drives, but this company I'm working for has 1.5TB of data that they'd rather not lose.  They DO have a backup but it's about a week old, and in the print media business, a week is hundreds of advertisements, articles and such.

So can I reset this LS420D to factory condition without losing data in an attempt to gain access to the online control panel?  And if so, HOW?
If no, then would it be possible to put the known-good 2tb drive in the new LS520DN0402, rebuild the array using one of the new 4TB drives and then swap out the 2TB drive with the other new 4TB drive and have it re-mirror to the larger capacity drive?

How is using a Buffalo LinkStation easier or more efficient than using a hardware RAID card in a dedicated computer where RAID tools (RAID partition repair, RAID Diagnostic Toolkit, etc.) can be utilized inside the Windows environment for recovery purposes??

Just looking for some help here, I'm at my wit's end with this 15 minute reboot to get nowhere.

Thanks in advance!!

You could create a VPN. A lot of routers do a VPN function. Once you get an IP on your network, then you could do it.

OK here we go... interesting results. Note I always properly shut-down and then disconnect the power. Re-connect the power and switch from off to on.

I switched to another ethernet port/cable as I needed to move the device from the basement to my office.

with ethernet cable attached:
power-on, blue power LED blinks; after some time the amber info/error LED comes on.  After boot is ready (blue power led steady) I see the IP address as a connected device in my router.  NAS-Navigator (2.91) finds the device.  There is no info, except for that a new (I52) firmware is available (I have 1.71).  I can access the device and its data

with ethernet cable detached...
power-on, blue power LED blinks; ; until boot ready the amber LED does not light up. Attach the ethernet cable. When I connect the cale, everything seems to work ok, I can access the data. One exception, the share is not automatically added to the finder on my mac.

I still need to investigate why the device did not ( and still does not) connect through the ethernet in the basement where it has been working for years.... And I am puzzled why the amber LED comes on when I startup with ethernet connected.

Another thing which happens... every time I do a refresh with the nasnavigator it tells me that the date and time of the NAS are incorrect...

And I can't find the place to download the latest firmware for this LS-WXL.

Just as an addition: after a hour or so, also in the latter case ( first boot, then connect ethernet) the amber LED comes on (Info/error)

Ahhggrr... is I52 the code for 'new firmware is available' (it is not in the manual, that stops at I47). and the amber LED comes on to signify this??? If I do not have the ethernet cable connected from boot, somewhere the device will check for new firmware and lite the LED? when the cable is connected from the start, then it is checked at boot time????  (by the way, the LED is solid on, nothing flashing...)

(still needs to check the cable/eternet port in the basement...)

You can't publish top level folders but you should be able to publish subfolders and files. What firmware version is installed?

Davo, I'll try the Navigator later today. Currently when I restart the box there is no error code, all which comes up is the well-known blue LED.  On the Ethn. port only the yellow LED lights up.  ( I seem to remember that there was an activity LED above the yellow one??)

Unlikely that the Ethernet port is broken.

What is the error code sequence on the info/error led?
