Count of reallocated sectors. When the hard drive finds a

read/write/verification error, it marks this sector as "reallocated"

and transfers data to a special reserved area (spare area).

This process is also known as remapping and "reallocated"

sectors are called remaps. This is why, on a modern hard disks,

you can not see "bad blocks" while testing the surface - all bad

blocks are hidden in reallocated sectors. However, the more

sectors that are reallocated, the more a decrease (up to 10% or

more) can be noticed in disk read/write speeds.

Current count of unstable sectors (waiting for remapping). The

raw value of this attribute indicates the total number of sectors

waiting for remapping. Later, when some of these sectors are

read successfully, the value is decreased. If errors still occur

when reading sectors, the hard drive will try to restore the data,

transfer it to the reserved disk area (spare area), and mark this

sector as remapped. If this attribute value remains at zero, it

RAID Configuration

On the RAID List screen, press the RAID Config button to go to the RAID Configuration screen. In addition to RAID disk information and status, this

screen lets you make RAID configuration settings. For more information on RAID, see Appendix C: RAID Basics.

RAID Level

You can set the storage volume as JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or RAID 10. RAID configuration is usually required only when you first set up the

device. A brief description of each RAID setting follows:

RAID Levels

Level Description

JBOD The storage volume is a single HDD with no RAID support. JBOD

requires a minimum of 1 disk. RAID 0 Provides data striping but no redundancy. Improves

performance but not data safety. RAID 0 requires a minimum of

2 disks. RAID 1 Offers disk mirroring. Provides twice the read rate of single

disks, but same write rate. RAID 1 requires a minimum of 2

disks. RAID 5 Data striping and stripe error correction information provided.

RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one

failed disk. RAID 6 Two independent parity computations must be used in order to

provide protection against double disk failure. Two different

algorithms are employed to achieve this purpose. RAID 6

requires a minimum of 4 disks. RAID 6 can sustain two failed

disks. RAID 10 RAID 10 has high reliability and high performance. RAID 10 is

implemented as a striped array whose segments are RAID 1

arrays. It has the fault tolerance of RAID 1 and the performance

of RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two

failed disks.

WARNING

If the administrator improperly removes a hard disk that should not be removed when RAID status is Degraded, all data will be lost.

RAID Settings

Using Disk Settings, you can select stripe size, choose which disks are RAID disks or the Spare Disk, as well as enter a name for each disk.

Chapter 7: Tips and Tricks

USB Storage Expansion

The N4100PRO supports external USB hard disks through its three USB ports. Once a USB hard disk has been successfully mounted, users can access the files on the USB hard disk under the USBHDD folder. The N4100PRO supports up to 6 USB external storage devices. All file names on the USB disk volume are case sensitive.

Before attaching a USB disk drive to N4100PRO, you have to partition and format it on a desktop computer or a notebook first. The attached device will be located at \\192.168.1.100\usbhdd\usb1\1\ where 192.168.1.100 means the IP address of N4100PRO, usb1 stands for the first USB device, and 1 stands for the first partition on disk #1, the USB disk drive. If it is an NTFS partition , NAS users can open or copy files from \\192.168.1.100\usbhdd\usb1\1 but cannot add new files or modify existing files.

NOTE

If you want to write to an USB storage device, the file system must be FAT32.

Adding a Spare Disk

With a RAID 1 or RAID 5 volume, you can add a spare disk after the initial RAID is setup. To add a spare disk, follow the steps below:

1. On the RAID Configuration Screen, tick the checkbox of the hard disk you wish to designate as a spare disk.

2. Click Add Spare. The disk will be configured as a spare disk. The system automatically rebuilds the spare disk when one of the disks in the RAID set fails.

Firewall Software Configuration

If you are using a software firewall (i.e. Norton Internet Security) and are having trouble connecting to the N4100PRO, you can try the following steps:

1. Double click the NIS icon on system tray, and then configure the Personal Firewall.

2. On the Programs page, find the SetupWizard.exe and change its permission to "Permit All". If it's not in the program list, use the Add or Program Scan buttons to find it.

3. On the Networking page, manually add N4100PRO IP address (i.e.

192.168.1.100) to the Trusted list.

Replacing Damaged Hard Drives

If you are using RAID 1, RAID 5, RAID 6, or RAID 10, you can easily replace a damaged hard drive in the Thecus N4100PRO while keeping your data secure with the system’s automatic data recovery.

Hard Drive Damage

When a hard drive is damaged and data in the RAID volume, the system LCD will display warning message also the system beeps.

Replacing a Hard Drive

To replace a hard disk drive in the N4100PRO:

1. Remove the tray with the damaged hard disk.

2. Unscrew the damaged hard disk and remove it from the tray.

3. Slide a new hard disk into the tray and fasten the screws.

4. Insert the hard disk tray back into the N4100PRO until it snaps into place. You can also lock it with a key if desired.

5. The LED blinks green when the HDD is accessed.

RAID Auto-Rebuild

When using RAID 1, 5, 6, or 10 on the N4100PRO, you can use the auto-rebuild function when an error is detected.

1. When a hard disk fails the system beeps and/or an email notification is sent to specified receivers.

2. Check the LCD to see which disk has failed.

3. Follow the steps mentioned above to replace the failed hard disk.

4. The system automatically recognizes the new hard disk and starts the auto-rebuild sequence to resume its status before the hard disk crash.

Chapter 8: Troubleshooting

Forgot My Network IP Address

If you forget your network IP address and have no physical access to the system, you can find out the IP address by either looking directly onto the N4100PRO’s LCD panel, or by using the setup wizard to retrieve the IP of your N4100PRO.

1. Start the Setup Wizard, and it will automatically detect all Thecus IP storage products on your network.

2. You should be able to find the IP address of the N4100PRO which you have forgotten in the Device Discovery screen.

Can't Map a Network Drive in Windows XP

You may have problems mapping a network drive under the following conditions:

1. The network folder is currently mapped using a different user name and password. To connect using a different user name and password, first disconnect any existing mappings to this network share.

2. The mapped network drive could not be created because the following error has occurred: Multiple connections to a server or shared

resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared

resource and try again.

To check out existing network connections, type net use under the DOS prompt. You may refer the URL below for more network mapping information.

Restoring Factory Defaults

From the System menu, choose the Factory Default item and the Reset to Factory Default screen appears. Press Apply to reset the N4100PRO to factory

default settings.

WARNING

Resetting to factory defaults will not erase the data disks, but WILL revert all the settings to the factor

stored in the hard

y default values.

Problems with Time and Date Settings

The administrator is able to select an NTP Server to keep the N4100PRO’s time synchronized. However, if the N4100PRO can not access the Internet, you may encounter a problem when setting the Time and Time Zone. If this happens:

1. Login to the Web Administration Interface.

2. Navigate to System > Time.

3. Under NTP Server, select No.

4. Set the Date, Time, and Time Zone.

5. Click Apply.

In addition, if the N4100PRO is able to access the Internet and you want to keep the NTP Server clock.isc.org by default, please make sure the DNS Server is correctly entered, thereby allowing the NTP Server name to correctly resolve. (See Network > WAN > DNS Server)

Appendix C: RAID Basics

Overview

A Redundant Array of Independent Disks (RAID) is an array of several hard disks that provide data security and high performance. A RAID system accesses several hard disks simultaneously, which improves I/O performance over a single hard disk. Data security is enhanced by a RAID, since data loss due to a hard disk failure is minimized by regenerating redundant data from the other RAID hard disks.

Benefits

RAID improves I/O performance, and increases data security through fault tolerance and redundant data storage.

Improved Performance

RAID provides access to several hard disk drives simultaneously, which greatly increases I/O performance.

Data Security

Hard disk drive failure unfortunately is a common occurrence. A RAID helps prevent against the loss of data due to hard disk failure. A RAID offers additional hard disk drives that can avert data loss from a hard disk drive failure. If a hard drive fails, the RAID volume can regenerate data from the data and parity stored on its other hard disk drives.

RAID Levels

The Thecus N4100PRO supports standard RAID levels 0, 1, 5, 6, 10, and JBOD. You choose a RAID level when you create a system volume. The factors for selecting a RAID level are:

• Your requirements for performance

• Your need for data security

• Number of hard disk drives in the system, capacity of hard disk drives in

the system

The following is a description of each RAID level:

RAID 0

RAID 0 is best suited for applications that need high bandwidth but do not require a high level of data security. The RAID 0 level provides the best performance of all the RAID levels, but it does not provide data redundancy.

RAID 0 uses disk striping and breaking up data into blocks to write across all hard drives in the volume. The system can then use multiple hard drives for faster read and write. The stripe size parameter that was set when the RAID was created determines the size of each block. No parity calculations complicate the write operation.

RAID 1

RAID 1 mirrors all data from one hard disk drive to a second one hard disk drive, thus providing complete data redundancy. However, the cost of data storage capacity is doubled.

This is excellent for complete data security.

RAID 5

RAID 5 offers data security and it is best suited for networks that perform many small I/O transactions at the same time, as well as applications that require data security such as office automation and online customer service. Use it also for applications with high read requests but low write requests.

RAID 5 includes disk striping at the byte level and parity information is written to several hard disk drives. If a hard disk fails the system uses parity stored on each of the other hard disks to recreate all missing information.

RAID 6

RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme (dual parity) Data is striped on a block level across a set of drives, just like in RAID 5, and a second set of parity is calculated and written across all the drives; RAID 6 provides for an extremely high data fault tolerance and can sustain two simultaneous drive failures.

This is a perfect solution for mission critical applications.

RAID 10

RAID 10 is implemented as a striped array whose segments are RAID 1 arrays. RAID 10 has the same fault tolerance as RAID level 1. RAID 10 has the same overhead for fault-tolerance as mirroring alone. High I/O rates are achieved by striping RAID 1 segments. Under certain circumstances, RAID 10 array can sustain up to 2 simultaneous drive failures

Excellent solution for applications that would h ave otherwise gone with RAID 1 but need an additional performance boost.

JBOD

Although a concatenation of disks (also called JBOD, or "Just a Bunch of Disks") is not one of the numbered RAID levels, it is a popular method for combining multiple physical disk drives into a single virtual one. As the name implies, disks are merely concatenated together, end to beginning, so they appear to be a single large disk.

As the data on JBOD is not protected, one drive failure could result t otal data los s.

Stripe Size

The length of the data segments being written across multiple hard disks. Data is written in stripes across the multiple hard disks of a RAID. Since multiple disks are accessed at the same time, disk striping enhances performance. The stripes can vary in size.

Disk Usage

When all 4 disks are of the same size, and used in RAID, N4100PRO disk usage percentage is listed below:

RAID Level Percentage Used

RAID 0 100% RAID 1 20% RAID 5 80% RAID 6 60%

RAID 10 50%

JBOD 100%

Appendix D: Active Directory Basics

Overview

With Windows 2000, Microsoft introduced Active Directory (ADS), which is a large database/information store. Prior to Active Directory the Windows OS could not store additional information in its domain database. Active Directory also solved the problem of locating resources; which previously relied on Network Neighborhood, and was slow. Managing users and groups were among other issues Active Directory solved.

What is Active Directory?

Active Directory was built as a scalable, extensible directory service that was designed to meet corporate needs. A repository for storing user information, accounts, passwords, printers, computers, network information and other data, Microsoft calls Active Directory a "namespace" where names can be resolved.

ADS Benefits

ADS lets the N4100PRO integrate itself with the existing ADS in an office environment. This means the N4100PRO is able to recognize your office users and passwords on the ADS server. Other major benefits ADS support provides include:

1. Easy integration of the N4100PRO into the existing office IT infrastructure The N4100PRO acts as a member of the ADS. This feature significantly

lowers the overhead of the system administrator. For example, corporate security policies and user privileges on an ADS server can be enforced automatically on the N4100PRO.

2. Centralized user/password database The N4100PRO does not maintain its own copy of the user/password

database. This avoids data inconsistency between the N4100PRO and other servers. For example, without ADS support, an administrator might need to remove a specific user privilege on the N4100PRO and each individual server. With ADS support, the change on an ADS server is known to all of its ADS members.

PREAMBLE

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program).

Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that

you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in

part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run,

you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the
