More Models

There apparently are newer models: TS-HTGL


In March 2006 Buffalo relased a new version of the TeraStation.

It is supposed to feature more current hardware like S-ATA disk.

For now please refer to the official site.


See hardwarePro for the new mainboard.

Where to upload Software?

If you have anything (Firmwares, Custom Firmwares, useful software packages) that might be useful for other Tera/Tera HS/TeraPro-users then send mindbender a private message in the forums. He will provide you with the needed information to upload files to


All linkstationwiki-admins & itimpi have full access and administrate the terastation-section:





The TeraStation Pro can be a member of Active Directory Enviroment of a Windows200x network.
To enable this Buffalo has released a beta firmware for this feature.

This firmware can be downloaded from http://de.buffalotech.com/downloads/TSPro-1.01-0.51-withAD.zip

And it uses an known password

AD integrated authentication only works by IP when username is < 10 or 12 chars (try using "administrat" instead of "administrator"!).. doesn't seem to include the domain


Some newly purchased units are coming out with a version 1.03 firmware. This firmware seems to have some issues, including the inability to set Active Directory settings(stays greyed out even after checking the AD checkbox, apparently not all 1.03 users are having this issue). Flashing with the 1.01 linked above seems to fix this issue.

In late June I had trouble with my TS Pro. Buffalo tech support suggested reinstalling the firmware. My box was at 1.03 but only 1.01 was available on the Buffalo website. I inquired and was told by Buffalo tech support 1.03 created more issues than it solved and was pulled for rework. My TS Pro subsequently died and I did a warranty exchange with the distributor (Dell). The replacement box contained 1.01, not 1.03.

Buffalo tech support does not recommend using 1.03.


Buffalo has a firmware Beta 1.04-0.00 or Beta 1.04-0.01 with a fix available on their (originally temporary) FTP site. According to Buffalo this should fix the issues that some users have been having when joining to their AD domains. It still does not appear to fix the name resolution issue (can connect to the device using AD users by connecting to "\\IPaddress" but not "\\Name").

-It seems that download link does not working, If someone have this firmware please let me know and I will provide hosting for it.

-It's working right now, but it seems go down intermittently. If someone has more reliable storage that would be great. Also, they have a new one out today: TSPro-1.04-0.01-CharFix. It is 1.04-0.01 instead of 1.04-0.00. Probably some sort of minor revision. --Wastedlife 05:09, 4 October 2006 (CEST)

Non-Official Firmware

The following firmware files have been provided by Entropy. There is always an inherent risk associated with updating your system. If your system breaks, you own both pieces. If you have feedback on the firmware, please leave a message on the Talk Page.

Terastation Pro Firmware by Entropy
Version Base Image Status Released Includes
1.01-1 Buffalo US 1.01-0.51-withAD Stable 2006-May-20 dropbear v??
user_nfs v??

md5*sum/sha*sum/dirname from busybox-0.60.5
user_nfs v??

Release Notes 1.01-2
The highlights of this version is that it replaces dropbear with openssh for compatibility reasons and includes a NFS v3 daemon so that files larger than 2G can be written to the Terastation via NFS. Most of the additional tools for this package are built using the Denx ELDK

  • Once you have flashed this image to your TSPro, you can ssh into the box using the admin account and whatever password you setup when you configured the box. The admin user has been added as a sudoer, so you can execute "sudo -s" if you want/need to use the root account.
  • Anytime the box is reflashed, the ssh host keys are regenerated.
  • If you are attempting to get public key authentication working, remember, all of the users' home directories are in /home, so if you setup public key authentication for one, it is for all because /home/.ssh is shared among all users. I would suggest changing your users home directory to /mnt/array1/home/USER (where USER is the username) so that your ssh keys are kept across firmware upgrades.
  • I created a link so that if you create a directory called /mnt/array1/web, you can serve files from that directory using your Terastation. I wouldn't exactly recommend putting it on the Internet though! Unfortunately, the master configuration does not allow for indexes or overrides, so you'll have to change the /etc/apache/httpd.conf file if you want directory listings. (Remember, you lose these changes when you reflash the box).

Release Notes 1.01-3 TEST1
This test release includes two changes, one minor and one major:

  • The program 'dirname' was added to the firmware so that a manual installation of TwonkyMedia server does not complain about it missing.
  • Previously, samba3 was only activated when joining a domain. Since samba3 has a bit more performance than samba2 this, it is now forced to run under all circumstances (samba2 is no longer on the firmware). This has some pretty far reaching consequences. It seems to work ok in my configuration, but it may not work for units operating in an domain settings. If you use your terastation in a domain, please test this and provide feedback.

Known Issues 1.01-2

  1. /tmp directory is only writable by root (this is actually a limitation of the original firmware). Workaround: Login and run "sudo chmod 1777 /tmp".

Wishlist for 1.01-3

  1. I will entertain any reasonable requests for add-ons (note: this does not mean something completely invasive like ripping out samba for an upgrade that will break the web interface).
  2. uPnP media server

Entropy's firmware worked great for me. I am having couple of issues it might be my inexpertise.

  1. Couldnt get the Pulic key authentication working. Tried using the tips on QandA.
  2. NFS - i was able to mount both on mac and linux and i tried to copy a file little over than 2GB and got error.

I would really appreciate any help.

Thanks a Million

Entropy could you tell me briefly how i can get V3 UNFS into the firmware. I will give it a shot. Appreciate your help.
- Nav

Thanks a lot for the info. It seems little bit out of my skills.

Tried to upload, firmware hung waiting for a response from Terastation, after 4 hours of trying everything including disabling firewalls, antivirus, pinging the terastation, I powered down. Now have a bricked terastation with System Error E00 MPU No response - desparate to resolve this - if I claim on warranty, will I get away with explaining that I was trying to flash the 1.01 legit version, since the process did not get far enough to transfer the image.dat file? Also, I am in Hong Kong where Buffalo support appears to be non-existant - has anyone had any dealings with Buffalo here?
- Nick
Did it hang at the end? beginning? middle? I believe that message indicates a hardware problem. The manual says "MPU is not responding" for that error code. You might try the emergency IP address and reflash or get it into emergency mode (although I can't find anything describing how; did it once by accident) and reflash. Try posting in the linkstationwiki.net forum to for advise. -Entropy

Emergency mode is described in the knowledge DB at [1] Power off the TS, press the init button while powering on again. Once the Power and DIAG LEDs will blink in unison you know that you are in 'Emergency Mode' and can now let go of the INIT button. -jutta

Thanks a lot Entropy. Firmware works fine for me.

Active Directory Authentication: Overcoming 1000 user limit

I had the same problem with the group limit and found no answers anywhere. After a bit of playing around I found the group and user list limit can be increased from 1000.

1. Telnet into the Terastation and login as root
2. edit /www/cgi-bin/module/BufDomainGroupListInfo.pm
3. In BufDomainGroupListInfo.pm script you will see each subroutine has a counter which is set to 1000 "if ($group_count > (1000-1)) { $flag++; }"
4. If you wanted to enumerate 5000 groups you would need to edit each of this to read "if ($group_count > (5000-1)) { $flag++; }".
5. write the file and bingo yer enumerating 5000 groups.

Joining Windows Domains

One problem is that the TeraStation will not allow you to join a domain that begins with a number. I had to rename my Windows domain because it began with a number. What was the programmer at Buffalo thinking? -Mike 2006 May 25

If you have a PDC with leading number(s) running send an Email to the helpdesk@buffalo-technology.ie. They can help you. - Joergl 2006 July 6

Have Terastation Pro 1TB. I can join it to my Small Business Server 2003 Active Directory, just fine. The network sees the TS-Pro just fine, but the user accounts are not updated on the TS. I have tried working with buffalo tech support, but the just keep telling me it is a Active Directory problem, that my AD is setup wrong.

I explained to them that AD in a SBS network has to be created in a exact patteren or it will not work right. This is created during setup. Explained to them that if I join the TS as a workgroup and not part of the domain then it works correctly. This points to an issues with TS and not my PDC. The TS is not retreiving the AD information correctly. I did flash to 1.03 no good.

Have found other posts elsewhere with the same problem in a SBS network. Has anybody been able to join to the SBS 2003 AD? Bryan July 2006

Is it realy not possible to join a domain which isn't in mixed mode? Thaek Sept 2006

Here is how I joined a native 2003 domain with a Pro 1TB:

0) Configure your proper domain settings under the web config (even if it errors out on join)
1) Connected a serial cable.
2) http://your_Terastation_IP/cgi-bin/task.cgi?task=console&param=on
3) Login as admin
4) Become root by entering sudo -s as a command and the admin password
5) /etc/init.d/smb restart
6) vi /etc/hosts
7) add the following: your.primary.DC.address FQDN.of.primary.DC (example: DC1)
8) /lib/ld.so.1 --library-path /usr/local/samba3/ /usr/local/samba3/net ads join -U Your_Domain_Admin_Account@Your.Domain.Qualifier
9) Enter the domain admin account password.
10) If you are still having problems connecting to the shares, make sure the time is correct (mine never gets it right) and repeat steps 5 - 9.

Also check the /etc/resolv.conf for old entries. For example a resolv.conf with 2 nameservers and a domain (called my.domain):
domain my.domain
search my.domain

With that, you should be off to the races. I am not sure why, but after a botched upgrade, I have manually do all of those settings each time I reboot the Terastation. But after I get it connected, it works great. Hope this helps.

TS-2.0tgl/r5 with firmware 1.03 DOES join AD
I have successfuly joined 10 (yes ten) TS-2.0tgl/r5 with firmware 1.03 to my single forest/tree/domain windows 2003 native AD domain. You do NOT need to use serial console or flash firmware BUT it was tricky:
-I had better luck using the NT name of my domain: MYDOMAIN instead of my.domain.name.tld
-I used hostname of DC instead of Fully qualified domain name becuase it would not fix in text box: "dc1" instead of "dc1.my.domain.name.tld"
-no wins was used
-remember! => The TS-2.0tgl/r5 1.03FW is not able to get more than 1000 users! A good way around this limitation is to use domain local groups. (Recommended design anyway)

-unpack, hookup, power on TS-2.0tgl/r5
-get dhcp settings or set all ip address info
-set time/date
-set hostname of your TS-2.0tgl/r5
-soft restart your TS-2.0tgl/r5
-add new computer account to AD using hostname you just set on TS-2.0tgl/r5
-make sure you set the new comuter account as "pre-windows 2000" computer (IMPORTANT)
-wait until ad replication completes
-login to TS-2.0tgl/r5
-go to network>workgroup/domain
-set domain, domain name, domain controller name (remember no FQDN and us NT name of domain)

Samba Performance?

Seems that I am the only one having problems with the bad samba performance from Windows clients (when having a few 1000 files in a directory). I assume that it has to do with the case insensitivity needed for Windows clients.

Is there a simple hack resolving this?

--Mbob 10:24, 3 October 2006 (CEST)

I use the TeraStation for SQL Backups... SQL dumps a 25gb to the TeraStation in approx 2.5 hrs... BackupExec then saves that to tape (Dell gigabit switches, SCSI U320 tape drive) in approx 4.5 hrs followed by a .75 hr verify... accessing TeraStation via IP address (for AD authentication).... I suspect RAID.

Samba 3?

The TSPro firmware with AD support (Entropy's firmware) runs Samba 3 - but only if you connect the TSPro to a Windows domain. If no domain connection is configured, the TSPro runs Samba 2!
To change this behaviour, you have to edit the file /etc/init.d/smb
You should create a copy of this file before changing anything!
Then you have to change the path to the samba2 binaries to samba3 - i.e. the line

cp /usr/local/samba2/wbinfo /usr/bin


cp /usr/local/samba3/wbinfo /usr/bin

I run my TSPro with this change since one week now and it runs Samba 3 always without any problems. The performance accessing the TSPro with Windows clients is much better than with Samba 2.
