Last post by Kane88 - June 25, 2026, 03:49:09 AMHi Trong. Are you still having a problem with this Linkstation Quad?
You should be able to swap the drives directly into a working LinkStation Quad - LS-Q4.0TL/R5. I have one of that model. Drop me a PM/DM and we can take a look at it.

Last post by partycat - June 08, 2026, 03:15:29 PMWhat ever the capacity of the RAID array is when it is initially created is what it will be stuck at regardless of rebuilding with larger drives.
To get access to the full capacity of the new drives you will need to delete the current RAID array and create a new one.

Storage / Buffalo Linkstation LS-WXL/R1 ...
Last post by BigRonnyV - June 05, 2026, 05:34:15 AMHi,
I have a Buffalo Linkstation with 2 HDDs (3TB) in RAID 1.
Recently, I had to replace an HDD; after nearly 30 hours of rebuilding, my NAS is running with 2 drives again (a new 4TB and an 'old' 3TB). Now I want to replace the old 3TB drive with a new 4TB drive as well. I think the old one is going to fail soon too; it has been running for over 10 years now.
Can I shut down the NAS, take out the old drive, and put in the new drive? Followed by a rebuild? Will I get the full 4TB then, or do I have to rebuild the entire RAID to utilize the full capacity?

Storage / Need help and Software for my ...
Last post by Vanni - May 11, 2026, 04:19:43 PMHello all ;)
I have an old Buffalo Drive Station DUO HD-WLSU2R1. It worked for many years without any problems. In the past i had placed/configured the NAS with 2x2TB HDDs (Raid1 - i mean the model could only Raid1....it's so long ago *g*)
Past a view month ago one HDD had a malfunction, but i only had a 1TB HDD to be replaced. On the NAS there were only 300GB with saved Logs a Backup and i thought that the Raid take the capacity of the smallest HDD. But when i plugged the 1TB into...the NAS didn't Powered on. Each HDD for itself in a single case for checking worked probably. I organized a second 2TB HDD from a friend but now - don't know what or when it happend - the good 2TB from the Raid is empty. Now i have the Problem that i don't find the org. CD and no Backup of it with the Software to configure the NAS with a new Raid and i didn't get the NAS to recognized by any Windows. I have tried Win95, Vista, Win7, Win8, Win10 each in x86+x64. I tried different Buffalo Raid Utilities Versions and DriveNavigators i found the Web but nothing worked. I tried to download the v1.01 from 2012.05.07 from the JP and US Site but both says that my 14 digits SN is not correct for the model. I think it's because i live in Germany (Europe) and this old model isn't in the international DB's anymore.
So i hope that anybody could help me to share the org software with me or hep/support me to configure my good old Buffalo to run again.
It would be very very nice
sincerely and take care all of you

Storage / Recover data from the LinkSta...
Last post by trongdu - April 29, 2026, 01:04:29 AMI have a LinkStation Quad - LS-Q4.0TL/R5. The controller failed with the message ACP_STATE_FAILURE.
If I plug the drives into another working LinkStation Quad - LS-Q4.0TL/R5 housing, do you think it will allow me to read the files? Can you suggest any other ways that I can recover the data from the drives?

Storage / DLNA problem on LS720
Last post by majbuzz - April 02, 2026, 10:39:22 AMI'm using the latest firmware for my Buffalo LS720D NAS 2.02.13
I don't know when this problem began. It had no issues before, but now the DLNA setting will not hold. I can click on it and it seems to be set but then it goes back to being off. I suppose that the most recent firmware is the problem. I seldom use the NAS for media streaming.
Any suggestions? If there's an earlier firmware version available, can I roll it back. Thanks in advance.

Storage / Re: slow copying to TS5810/580...
Last post by Kane88 - March 29, 2026, 07:33:15 PMSo on to Checking the TS5810 manual, chapter 3:
https://www.buffalo.jp/s3/guide/ts5010/global/99/en/index.html?Chapter3#h2anc0
There is no information about the SMB section at all. And no mention of any configuration items for the protocols either. I went through the rest of the manual, and found nothing.
That information should be right here in Chapter 3.
Buffalo dropped the ball here too. Why?
So I checked TS 5810 console: File Sharing > SMB
SMB Encryption is set at Default. But we have no idea what 'default' is, nothing in the manual- says what default is.
Perhaps later, I might try with this setting disabled, and re enabling SMB Encryption on the Windows PC.
But, even if I do that, it will not solve my problem for the 5800 series.
Going to the TS 5800/5400 console: File Sharing > SMB
There are no Settings for SMB Encryption at all. We have no idea if there is any SMB Encryption or not. I assume there is, given turning SMB Encryption off on the PC, did make file transfers to the 5800 and 5400 units I have.
So yeah, Buffalo has indeed dropped the ball here somewhat. I don't think passing the buck to Microsoft solves this one folks, I really don't.

Storage / Re: slow copying to TS5810/580...
Last post by Kane88 - March 28, 2026, 03:58:40 AMSo these settings from the article, really do work.
Fix Slow Network Copy Speeds in Windows 10/11 by Tuning SMB and Disabling Throttling
I also added the robocopy /J switch and wow. Even copying between terastations (TS 5400+ TS5810) from the 6300 also is up to where it should be, a 95MB/sec average. I know with this machine that it was definitely at 50MB/sec in the past, without the robocopy /J switch to copy BETWEEN terastations.
I did NOT enable jumbo frames, as the article points out: Jumbo frames: Only enable jumbo frames if every device on the path supports it correctly (PC NIC + switch + NAS). Misconfigured jumbo frames often reduce performance.
I've seen good results with three machines, the HP 800 G6 10th gen, an HP 800 G3, and also an HP 800 G1. All three have Intel RAID chipsets and all are copying at at least 200MB/sec now- about 4x higher than what they were beforehand.
So to find out the cause: I went in reverse order:
I started with putting the registry values back to what they were, and then rebooted. Sure enough, these registry changes had no effect, the copy went ok at the right speed.
Then, I used powershell to turn SMB encryption back on, and rebooted again.
And sure enough, there it went back to the way it was. Slow Copying at 50MB/sec from the Intel HP 800 G3 RAID PC to the TS5810.
So it has been narrowed down to this SMB Require Encryption setting.
And that folks is definitely- THE culprit.
----------
Now that said, this part here from the article does seem to be something on the buffalo side of things:
SMB encryption: If SMB encryption is enabled on the share, it can heavily tax CPUs. Use it only where needed.
(Kane88: Obviously the share IS the source, which IS the Terastation itself)
Now the questions for the Buffalo Team (if they still read these forums are) are:
Will they give us options in the future, to change SMB Encryption settings in the Terastation Console?
Why do I need to turn SMB encryption OFF (to get any decent copying speed), simply because I have Intel SATA RAID chipsets in some of my computers?
Why does the terastation copy ok at the proper speed, with a PC that does not have an Intel SATA RAID chipset?
And please, let's not point fingers completely at Microsoft about this one.
----------
Given that when the SMB encryption setting is on, I can copy between two windows PCs just fine:
I still feel that even partially, this problem resides with the Buffalo firmware / within the Linux OS config they are using.
I am not knowledgeable enough to test this out with Linux. But given people have had problems with SLOW SMB using things like Open Media Vault, etc that are Linux based: I assume this SMB encryption problem is universal (to whatever extent in the Linux OS itself), no matter the operating system.
IF SMB encryption indeed is ON in the Terastation 'firmware' (Which I presume it is, yet I have no way to check and verify this, that would require the help of 10... or another Linux or Debian Wizard, who knows how to check that) I could understand why. Buffalo would want to protect the data of their business customers, first and foremost, which makes senese.
But as we see here this is done at the cost of decent SMB speed, for some machines.
So you be the judge. I have some older terastations I might try this out with at some point. And who knows, maybe this effects the speed of the Linkstations out there too, no idea.
Please note I do not work for buffalo, and you try these settings- at your own risk. Before you do anything, back up the registry setting beforehand, just as that article says to do!!! And your mileage may vary, this worked for me, but your configuration and situation, might be different.

Summary
What change was kept in Win11 25H2:
Set-SmbClientConfiguration -RequireSecuritySignature $false
What was tested (it was later removed and reverted back to its default settings)
Back up the registry key
Press Win + R, type regedit, press Enter.
Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
Right-click SystemProfile → Export (save a .reg file).
Set NetworkThrottlingIndex to "disabled"
In the same key, find NetworkThrottlingIndex.
If it doesn't exist: Right-click → New → DWORD (32-bit) Value
Set its value to:
Hex: ffffffff
Decimal: 4294967295
Click OK.
(Optional) Increase system responsiveness
In the same location, you may see SystemResponsiveness.
Some users set it to 0 (decimal) for maximum responsiveness to network tasks.
If present, set to 10 or 0 based on your use (gaming/streaming vs file server).
When in doubt, leave it alone.
Reboot
This change typically requires a reboot to fully apply.

Storage / Re: slow copying to TS5810/580...
Last post by Kane88 - March 24, 2026, 06:58:02 AMSo now I found this. And tried the settings in here. I'm not really big on disabling signing on the Win 11 25H2 PC, but I need to do some testing. My first quick test copying a 5gb image file FROM the TS 5810 to an Intel RAID 0 array is now at about 216MB/sec
Still, its kind of wierd I need to be editing the registry to make this work.
https://windowsforum.com/threads/fix-slow-network-copy-speeds-in-windows-10-11-by-tuning-smb-and-disabling-throttling.399062/
When I get a chance to test more, I'll post again.
