• File and folder names may contain up to 255 single-byte characters.
• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.
• If shared folders are accessed from a Mac, information files for the Mac may be generated automatically. Do not
delete these files. If they are deleted using Windows, this may prevent further access from a Mac.
• The LinkStation belongs to the default zone in AppleShare; the zone cannot be specified.
• When files are copied to the LinkStation or to a USB drive connected to the LinkStation, file information such as
date created, date modified, and other date information may be updated or changed.
• During a file transfer, if settings are changed, the file transfer operation may be aborted.
• File copying to the LinkStation is protected by a journaling file system. If the Ethernet cable is disconnected or a
power outage occurs while copying data, the following may occur:
◦ Preset data such as the LinkStation name, users, and groups may be erased.
◦ An incomplete file may be copied and the file can no longer be deleted. If this happens, restart the
LinkStation, delete the file, and perform the copy operation again.
Recycle Bin
To protect your data from accidental deletion, you may configure your LinkStation to use a recycle bin instead of
deleting files immediately. The recycle bin will only work with SMB connections.
Read-only Shares
By default, new shares are set with read and write access, but you may change the attribute to Read Only at Attribute.
Read-only shares and HFS Plus-formatted USB drives will have “(Read Only)” added to comments in File Explorer.
Note: Configure read-only file attribute in Settings. Configuring them from within Windows is not supported and
may cause unexpected behavior.
22

Hidden Shares
Chapter 3 File Sharing
If hidden shares are enabled, shared SMB folders will not be displayed in Network, and only certain users are allowed

hidden shares. A USB drive is not available for a hidden share.
2 Click the “Hidden Share (SMB Only)” checkbox and click OK.
Notes:
• If protocols other than “SMB” or “Backup” under “LAN Protocol Support” are enabled, the hidden shares option will
be grayed out and cannot be selected.
• Configure hidden share attribute in Settings. Configuring them from within Windows is not supported and may
cause unexpected behavior.
To access a hidden folder, open File Explorer in your computer and enter “\\LinkStation name\shared folder
names$\” into the address bar. For example, if the LinkStation name is “LSXXX001” and the shared folder name is

Configuring Active Directory
If there is an Active Directory environment, the LinkStation will use account information from the Active Directory
domain controller to set access restrictions for LinkStation’s shared folders. There is no need to perform individual
account management for the LinkStation. If multiple LinkStations are installed on the network, the account
information is centrally managed in Active Directory, greatly reducing the operations required for installation and
management.
Note: The LinkStation supports a domain environment with a maximum 1000 users and 1000 groups.

12 Click OK.
Notes:
• If you change the LinkStation’s name, you will no longer be able to use domain users and groups or access
restrictions. To repair this, rejoin the domain.
• To have the LinkStation join an Active Directory domain, configure it to use a DNS server that can resolve names
for the Active Directory domain.
• After building an Active Directory domain, the administrator password for joining the domain must be changed
at least once, or joining the Active Directory domain will fail.
• The DNS name and NetBIOS name of Active Directory domains should be identical.
• If both read-only and read and write permissions are given, the user will have read-only access. The most
restrictive access setting will apply.
• If there are more than 5 minutes difference between the LinkStation’s clock and the domain controller’s clock,
joining the domain or authenticating domain users and groups may fail. For best results, use an NTP server to set
the time for all network devices.
• To use the LinkStation as a member server in an Active Directory domain, the LinkStation should be logged in to
the domain and accessed from a computer that is not a member of the domain with a valid domain account.
• If the LinkStation is a member server of an Active Directory domain, you cannot connect as a guest user via AFP.
• If your LinkStation is a member server in an Active Directory domain and you change the authentication method
to “Workgroup”, the account on the domain controller will not be deleted automatically.
35
Page 37
• When the LinkStation joins an Active Directory domain, FTP is disabled. Before using FTP, move the FTP switch
Chapter 3 File Sharing
back to the on position.
• Don’t disable the SMB protocol while Active Directory is used for access restrictions. If you do, you will need to
enable SMB again and reconfigure AD from scratch.
Configuring NT Domain
If there is an NT domain environment, the LinkStation will use account information from the NT domain server
to set access restrictions for files and folders on the LinkStation. There’s no need to perform individual account
management for the LinkStation. If multiple LinkStations are installed on the network, the account information is
centrally managed in the NT domain, greatly reducing the operations required for installation and management.
Note: The LinkStation supports a domain environment with a maximum of 1000 domain users and 1000 groups.

restrictions. To repair this, rejoin the domain.
• If both read-only and read and write permissions are given to a user, the user will have read-only access. The most
restrictive attribute will apply.
• If a domain username is more than 20 bytes long, the LinkStation truncates it to 20 bytes.
• To use the LinkStation as a member server in an NT domain, the LinkStation should be logged in to the domain
and accessed from a computer that is not a member of the domain with a valid domain account.
• If the LinkStation is a member server of an NT domain, you cannot connect as a guest user via AFP.
• When you change the user or group settings on the domain controller, these changes may not take effect
immediately on the LinkStation until it is rebooted.
• If your LinkStation is a member server in an NT domain and you change the external authentication method to
“Workgroup”, the account on the domain controller will not be deleted automatically.
• If the LinkStation has joined a domain network, you cannot connect to it via FTP.
• Don’t disable the SMB protocol while an NT domain server is used for access restrictions. If you do, you will need
to enable SMB again and reconfigure the NT domain settings from scratch.
User Authentication with an External SMB Server
LinkStations on your network can be linked to an authentication server for centralized management of user
accounts and passwords. The authentication server should be another Buffalo NAS device. Other external SMB
authentication servers are not supported.
Notes:
• Disable SMB2 before using external authentication.
• Access restrictions for local users and groups will still apply to shared folders if an external SMB server is used for
authentication.
• The procedure below contains methods to automatically register external users. You can also manually add
external users by converting them from local users. Refer to the “Converting Local Users into External Users”
section below for more details on converting local users.
1 From Advanced Settings, click Network.
2 Click to the right of “Workgroup/Domain”.

Chapter 3 File Sharing
5 Click Yes .
6 Enter a workgroup name. Select “Authenticate local and external SMB server users” and enter the SMB server’s
IP address. You can also specify a server from another subnet.
7 If “Automatically register users who access LinkStation folders” is checked, users that access any of the
LinkStation’s folders will be automatically registered as external users. This process only applies with folders
that have access restrictions disabled. After new external users are added, disable this option to limit the
number of authenticated user accounts.
If “Restrict user registration to a single folder” is checked, the LinkStation will automatically create a readonly shared folder. Enter the shared folder name. Users that access this specific folder will be automatically
registered as external users. If this setting is de-selected at a later time, the LinkStation will automatically
delete the folder.
Note: Connect to the authentication folder via SMB, not FTP or AFP. Automatic user registration may not
work with OS X 10.8 (or later) the first time. If this occurs, try rebooting the LinkStation, then access the
authentication shared folder again.

Notes:
• Users that are automatically registered belong to the “hdusers” group. They can be added to other groups from
within groups settings. Added users will be listed in “Users” > “External Users”. To delete a user that was registered
automatically, select that user and click Delete External User.
• If both read-only and read and write permissions are given to a user, the user will have read-only access. The most
restrictive attribute will apply.
• To access access-limited shared folders from OS X 10.7, use AFP instead of SMB, under “LAN Protocol Support”,
select the “AFP (Mac)” checkbox on the destination folders to use AFP.
40
Page 42
• If access restrictions are set for users and groups from the authentication server, guest and anonymous
Chapter 3 File Sharing
connections will not be possible with AFP connections.
• FTP connections do not support authentication with an external SMB server.
• If using a Windows PC for external authentication, the default Windows SMB security settings may need to be
changed. An easy way to do this is to run the File Sharing Security Level Change Tool, available from this product’s
download page on the Buffalo website. This utility will let you easily change or restore your Windows security
settings to work with external authentication.
Converting Local Users into External Users
If using an external SMB server for authentication, you may convert any local users into external users. This way, the
LinkStation will have a user list that matches the users in the external SMB server, and access restrictions for this
LinkStation’s shared folders may be assigned to the converted “external” users.
Follow the procedure below to convert a local user into an external user. If a local user is converted, their user
information (including passwords) will be removed from the LinkStation. External users cannot be reverted to local
users.
Note: External authentication should be enabled before local users can be converted. For more information on
external authentication, refer to the “User Authentication with an External SMB Server” section.

Chapter 4 Storage Management
RAID Modes
LinkStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are
installed in your LinkStation.
Notes:
• If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter.
Always back up any important data before performing actions that affect your RAID array.
• Drive capacity is displayed in Settings in actual gigabytes. The Properties window in Windows may show GiB
instead, which will be smaller number.
• After the RAID mode is changed (except when creating a RAID 0 array or JBOD), the LinkStation performs a RAID
scan that will take about 10 hours per TB. File transfers are slower during this period. While the I17 message is
displayed in NAS Navigator2, do not turn off the LinkStation. If you do, the RAID scan will start over.
RAID 1
Combines 2 drives into a mirrored array. The usable space in the array is the capacity of a single drive. Identical data
is written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive. As long as one
drive in the array remains undamaged, all data in the array can be recovered.
RAID 0
Combines 2 drives into a single array. The usable space is the total space of all drives used. This simple RAID mode
offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data in the
array is lost.
JBOD
This mode uses the drives inside the LinkStation as individual drives. The usable space you can use is the total
capacity of all drives in the LinkStation. If any drive is damaged, then the data on that drive is lost.
Working with RAID Arrays
To change RAID settings, navigate to Drives > RAID in Advanced Settings.
Using JBOD
With JBOD, each drive in the LinkStation is addressed separately. To put drives from an array into JBOD, follow the
procedure below.
1 From Advanced Settings, click Drives.

Note: Normally, after a RAID array is created, it is “resynced”, which optimizes the array, making it more stable.
The resyncing process takes about 1 hour per terabyte of space in the array. File transfers will be slower during
this period, but the array will remain fully usable. The I17 message will be displayed in NAS Navigator2 during
44
Page 46
the resync. If you clear the “Resync after creating the RAID array” checkbox, the resync will be skipped. If the
Chapter 4 Storage Management
LinkStation is rebooted during the resyncing process, the resync will begin again from the beginning.
9 The “Confirm Operation” screen will open. Enter the confirmation number, then click OK.
10 Click OK when completed.
After changing the RAID mode, create a shared folder.
RMM (RAID Mode Manager)
You can create a RAID array without erasing the data on the drive by using RMM (RAID Mode Manager). You must
have two drives available in JBOD (not in a RAID array) to build the RAID 1 array with RMM.
1 From Advanced Settings, click Drives.
2 Click to the right of “RAID”.

Adding an External Drive
Connecting an External Drive
Your LinkStation includes a USB port and you can connect an external drive to this port. Once connected, it appears
as a shared folder on the LinkStation. Formatted drives are detected automatically. Unformatted drives should be
formatted in Settings.
After a USB drive is recognized, Windows adds “usbdisk x” in File Explorer, where “x” is the USB port which the drive is
connected.
Note: Backup data from macOS may include characters that cannot be written to FAT16 or FAT32 drives such as
“.DS_Store”. For best results, reformat the drive before using it as a backup target.
Compatibility
The following devices are supported by the LinkStation:
• USB storage devices
• Card readers (except for card readers that can recognize two or more memory cards)
Buffalo external USB drives are recommended but DUB and DIU series drives are not supported.
Supported file systems for external drives are below:
• FAT32
• Ext3
• XFS
• NTFS
• HFS Plus (read-only)
Connect only one device to a USB port of the LinkStation. Some external drives with automatic power-on don’t turn
on automatically when connected to the LinkStation. Use their manual switch to turn them on. Be sure to connect
only one bus-powered drive at a time. If there is insufficient bus power for your USB drive, connect its AC adapter.
Note that only the first partition of a connected USB drive is mounted. Additional partitions are not recognized.

Dismounting Drives
Chapter 4 Storage Management
If the LinkStation is powered on, dismount drives (internal and external) before unplugging them. You may
dismount external drives with the function button, or dismount any drives from Settings. If the LinkStation is off,
then all drives are already dismounted and may be unplugged safely.
Note: If you unplug your external drives without dismounting them, Settings may still show “usbdisk” in the shared
folder list. Reboot your LinkStation to clear it.
Dismounting with the Function Button
Press and hold the function button for 3 seconds. The white function LED will go out as all attached USB drives are
dismounted. You may now unplug them safely.

Notes:
Chapter 4 Storage Management
• Do not turn off or disconnect power to the LinkStation while formatting a drive.
• For drives of 2.2 TB or larger, make sure that the “GPT Partition” checkbox is selected. If you accidentally format a
larger drive without GPT, disconnect and then reconnect it before reformatting with GPT.
Erasing Data on the LinkStation Completely
Under some circumstances, data from formatted drives can be recovered. The drive erasure process in this section
does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive
in a way that makes it nearly impossible to recover with current tools. The LinkStation will then be in the following
state:
• Both drives in JBOD
• An empty shared folder on each drive
• All settings returned to their default values
• All logs deleted
1 From Advanced Settings, click Management.
2 Click to the right of “Restore/Erase”.
3 Click Erase LinkStation.
4 The “Confirm Operation” screen will open. Enter the confirmation number, then click OK.
5 All data on the LinkStation will be permanently erased.
Disk Quotas
You can set a drive quota to limit drive space for each user or group. You can also set a threshold. If the drive space
exceeds the configured threshold, a notification email will be sent. To configure email notifications for the drive
quota, refer to the “Email Notification” section in chapter 8.
Notes:
• When using quotas, disable the recycle bin or empty the trash folder often. The limited space includes the space
used for trash.
• Quotas apply per drive or per array. If a quota is set to 1 GB, each array or drive can use a maximum of 1 GB.
• Quotas cannot be set for external drives connected to the LinkStation.
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.

Drive Replacement
If a drive fails, NAS Navigator2 and Settings will show an error message.
Notes:
• Do not replace a running drive while the LinkStation is turned on. Power down the LinkStation before changing
the drive. While the LinkStation is running, never unplug or remove drives without dismounting them first.
• If using the LS220DR series LinkStations, use a Buffalo OP-HDBN series drive as the replacement drive. For the
replacement drive of other series LinkStations, use a Buffalo OP-HDBST series drive. The replacement drive should
be the same size or larger as the original drive. If a larger drive is used, the extra space will not be usable in a RAID
array.
• If sending a defective drive to Buffalo for replacement, please keep the cartridge as Buffalo will only replace the
drive and not the cartridge.
• To avoid damaging the LinkStation with static electricity, ground yourself by touching something made of metal
before handling any sensitive electronic parts.
• After a drive is replaced, it will take about 30 minutes before normal file reading and writing are restored. Settings
may not be accessible during this period.
• Do not change the order of the drives in the LinkStation. For example, pulling out drive 1 and replacing it with
drive 2 may cause data to be corrupted or lost.
• If a new drive is not recognized after installing it, click Rediscover Disk in Settings.

• Hostname: IP address of the LinkStation
• Username: The LinkStation’s username
• Password: The LinkStation’s password
• Port: 21
Accessing the LinkStation with an Anonymous User
To allow anonymous access to your FTP share, disable access restrictions. Configure your FTP client software with
the following settings for anonymous FTP access:
• Hostname: IP address of the LinkStation
• Username: Anonymous
• Password: Any character string
• Port: 21
Notes:
• If the LinkStation joins a domain, domain and anonymous user cannot access it.
• Shared folders connected by FTP are available from the “/mnt” directory. The examples of default locations are:
/mnt/array1/share
/mnt/disk1/share
/mnt/usbdisk1
• Don’t use FTP to share files and folders with multibyte characters in their names with a Mac. Use an AFP or SMB
connection instead.
• If a file was created or copied using AFP, you may not be able to delete it using an FTP connection. If this occurs,
use an SMB or AFP connection instead to delete the file.
• For FTP connections, make sure that the total filename including the directory path is 250 single-byte characters
or less.

Backing Up to a Buffalo NAS Device
You can back up the LinkStation folders to another shared folder on the same LinkStation, a connected USB drive, or
a shared folder on another Buffalo NAS device, either on the same network or on another network.
Preparing a Backup Destination
First, configure a shared folder on a Buffalo NAS device or connected USB drive as a backup destination. The
following procedure explains using another shared folder on the LinkStation as a backup destination. The procedure
may vary depending on which Buffalo NAS device is selected as a destination.
1 From Advanced Settings, click File Sharing.
2 Click to the right of “Folder Setup”.
3 Choose the folder to set as a backup destination.
4 Click Edit.
5 Under “LAN Protocol Support”, select the “Backup” checkbox.
6 Enter the desired characters into the remote backup password field and click OK.
Notes:
• You may leave this field blank if you do not want a backup password, but for security reasons we highly
recommend entering one for the shared folder. If a backup password is configured for the shared folder, that
folder will not show up as a target for the backup source or backup destination when configuring a backup
job on another Buffalo NAS device unless it’s entered. You may create multiple folders using different backup
passwords for backup, but only one password can be used on the LinkStation. Folders that are configured with a
different password cannot be used.
• A backup password is not available when a new shared folder is created by a power user.

Notes:
• Up to 8 backup jobs can be configured.
• To back up data between LinkStations or TeraStations on a network using jumbo frames, make sure that both
devices are configured to use identical (or similar) Ethernet frame sizes. If Ethernet frame sizes are significantly
different, the backup job may not be properly performed. In such a case, select the default frame size (1500
bytes).
Backup Modes
The following types of backup jobs may be selected:
Mode Files included
The first backup job runs like a normal backup. The backed up data will be
stored under the automatically-created folder of the job name. As each
Overwrite (differential)
Overwrite (incremental)
Normal backup
additional backup job runs, files are added to and deleted from the backup
folder. The backup destination folder will always be the same size as the
backup source folder.
The first backup job runs like a normal backup. The backed up data will
be stored under the automatically-created folder of the job name. In
subsequent backups, files added to the source as well as files deleted from
the source are kept in the backup folder.
All files in the source will be backed up to the destination. Whenever the
backup job runs, the folder with the name as the date when the backup job
runs will be created automatically and the backed up data will be stored
here.
