</ul>
<p>Shut down your Macintosh from the <i>Special</i> menu in the Finder. Boot up the computer again. Your Macintosh should now start up properly.</p>
<p><b>Note</b>: The FireSCSI extensions must be enabled if you are using the QuickStripe RAID 0 functionality of the Maxtor Utilities and may be required for other manufacturers&#8217; FireWire devices to function properly. Do not disable the FireSCSI extensions if you have set up a FireWire RAID with the Maxtor Utilities or if the FireSCSI extensions are required by another FireWire device. As a workaround, unplug your Maxtor Personal Storage drive from the FireWire port on your Mac before starting up the computer. Turn on your Mac, wait until it has completed the startup process, and then connect the drive to the FireWire port on the computer. The drive should be recognized properly by the system.</p>

</ul>
<p><strong>Note</strong>: Although you will rarely see reference to Seagate BlackArmor 420, all FAQs found here refer to both Seagate BlackArmor NAS 440 and Seagate BlackArmor NAS 420 products together unless otherwise noted.</p>
<p><strong>How many Users can the Seagate BlackArmor support?</strong></p>
<p>The Seagate BlackArmor servers are targeted to the SMB/SOHO customer and are designed to support up to 50 clients. </p>
<p><strong>What is Seagate BlackArmor Backup and what can it actually back up?</strong></p>
<p>Seagate BlackArmor Backup is a comprehensive Backup Utility made by Acronis and skinned for use with the Seagate Black Armor Family. BlackArmor Backup can perform Full-System, Incremental and Custom backup</p>
<p><strong>How many Seagate BlackArmor Backup client licenses are provided with the Seagate BlackArmor NAS 440?</strong></p>
<p>BlackArmor ships with 10 licenses out-of-the-box, however, additional licenses can be purchased in 2 and 5 -set increments on the Seagate Website. </p>
<p><strong>Can I perform a Full System Backup and/or Restore with the Seagate BlackArmor Backup software?</strong></p>
<p>Yes you can use BlackArmor Backup software to perform Full System Backup of your Windows XP and/or Vista computer.   <br />You can also recover from system problems via the use of BlackArmor Recovery software included on the CD. With this CD, you can boot up your system, access the BlackArmor and Restore from a complete system backup.</p>
<p><strong>Can I use Time Machine to Back Up my Mac to the Seagate BlackArmor NAS 440?</strong></p>
<p>Apple does not support the use of Time Machine with networked drives, with the exception of its own Time Capsule. </p>
<p><strong>What is the difference between Port Aggregation and Port Replication? </strong></p>
<p>The server’s two LAN ports can be configured for <em>link aggregation</em>, which means you can connect both LAN ports to your network at the same time and improve transfer performance. Your BlackArmor server then uses both network connections simultaneously so that it can transfer data at a faster rate.</p>
<p><strong>Note: </strong>The speed of your network connection doesn’t change. With link aggregation, your BlackArmor server sends and receives information through both LAN ports at the same time, which increases “throughput”. Link aggregation is not unlike using two hoses to fill a bucket instead of one—using two hoses doesn’t make the water flow any faster, but the bucket fills more quickly. </p>
<p>Alternatively, you can use one LAN port to connect to your network and the other LAN port to set up <em>replication</em>, or archive backup, where an exact copy of the data on your BlackArmor server is created and maintained on a second BlackArmor server. </p>
<p><strong>Can I access the BlackArmor NAS 440 from PCs that are already part of a workgroup or domain?</strong></p>
<p>Yes – by default, the Seagate BlackArmor NAS 440 is configured to join the WORKGROUP Workgroup. However, with a couple of setting changes and Domain Admin authentication, the NAS 440 can become part of a Domain. It is important to point out that other factors need to be addressed before this product can effectively participate in Active Directory. Contact your System/Domain Admin if you require assistance.</p>
<p><strong>Is the Seagate BlackArmor NAS 440 compatible with Linux?</strong></p>
<p>Yes and No. The Seagate BlackArmor NAS 440’s Web UI can enable NFS access to shares when created or modified. These shares can then be mounted using various Linux GUI (e.g., KDE or Gnome) and/or Command-Line usage. Refer to your Linux documentation for more information.</p>
<p><strong>What Protocols are supported?</strong></p>
<p>The following Network Protocols are supported:</p>
<ul>
<li>HTTP </li>
</ul>
<ul>
<li>HTTPS </li>
</ul>
<ul>
<li>CIFS </li>
</ul>
<ul>
<li>FTP </li>
</ul>
<ul>
<li>NFS </li>
</ul>
<ul>
<li>Bonjour </li>
</ul>
<ul>
<li>Microsoft Rally </li>
</ul>
<p><strong>How do I know if my printer will work when connected to the Seagate BlackArmor NAS 440?</strong></p>
<p>The Seagate BlackArmor provides support for USB Printers when properly configured. Windows Users should configure a Network Printer and Mac Users should do the same or trying connecting through a Windows printer if one is configured for Windows Users.</p>
<p><strong>Note</strong>: USB, All-In-One (AIO) Printers are not supported</p>
<p><strong>What Levels of RAID are available with the Seagate BlackArmor NAS 440?</strong></p>
<p>By default, the Seagate BlackArmor NAS 440 comes with a pre-configured RAID 5 Volume. The Seagate BlackArmor 420 comes with a pre-configured RAID 1 Volume. However, both can be set with user-configurable RAID 0/1/5/10 &amp; JBOD volumes. By default the NAS 420 can be configured as RAID 0 or 1. The other RAID schemes become available when two (2) more drives are added to the unit. </p>
<p><strong>Are the hard drives in the Seagate BlackArmor NAS 440 hot – swappable? </strong></p>
<p>In the event of a Drive Failure, users can run the BlackArmor in a degraded state and replace the defective drive with a good drive. After which, you can rebuild the RAID volume using the BlackArmor Manager’s Web UI.</p>
<p><strong>Note</strong>: Never remove more than one (1) drive from the BlackArmor at any given time while power is on. Failure to do this may result in data loss.</p>
<p><strong>What other replacement parts are available for the Seagate BlackArmor NAS 440?</strong></p>
<p>Along with Hard Drives, you can also replace the following accessories:</p>
<ul>
<li>Cooling Fan </li>
<li>Hard Drive Tray/Sled </li>

Depending on the status of your drive, or dual <b>RAID</b> drive, the WD icon will do different things.</p>
<ol>
<li>The WD icon is also the way that you access the drive&#8217;s status, or as in this case, the drive&#8217;s <b>RAID</b> status. When the <b>RAID</b> is healthy, you will see the blue WD icon. Clicking on the <b>WD icon</b> opens a short menu that leads to launching the <b>RAID</b> Manager. From there, you can reconfigure the <b>RAID</b> mode of the drive.
<p><img border="1" alt="Image" src="http://support.wdc.com/images/kb/rm_01.jpg" /></p>
</li>
<li>If something happens to the <b>RAID</b> status of the drive, a warning will be issued.
<p><img border="1" alt="Image" src="http://support.wdc.com/images/kb/rm_02.jpg" /></p>
</li>
</ol>
<p><b>For <b>RAID</b> 1 (Mirrored)</b></p>
<ol start="start">
<li>The WD logo will flash to dark blue, if it&#8217;s a degraded <b>RAID</b> 1.
<p><img border="1" alt="Image" src="http://support.wdc.com/images/kb/rm_03_04.gif" /></p>
</li>
<li>When you click on the <b>WD icon</b>, a menu opens up showing the <b>WD My Book <b>RAID</b> USB</b>. When you rollover it, another menu pops up giving the status of the drive. In this case, it shows <b><b>RAID</b> Status: Degraded</b>. Now click on <b>Launch WD <b>RAID</b> Manager</b>.
<p><img border="1" alt="Image" src="http://support.wdc.com/images/kb/rm_05.jpg" /></p>
</li>
<li>When you click on <b>Launch WD <b>RAID</b> Manager</b>, a <b>Drive Configurations</b> window opens up showing what has happen. In this case, a drive has failed and needs to be replaced.

<li>You will notice in <b>Drive Configurations</b> that you still show a capacity. This is because the drive was part of a <b>RAID</b> 1 configuration, and the data is still available. Once the drive is replaced the data will be rewritten to the new drive.

<li>Again, a warning would be issued, if the drive&#8217;s <b>RAID</b> status was having problems. In this case, the flashing red means that you are having a problem with your <b>RAID</b> 0 configuration being degraded.

<li>This time, you would see a red bullet in front of <b>WD My Book <b>RAID</b> USB</b> instead of a yellow bullet, as is found when a <b>RAID</b> 1 Drive has degraded. And in the menu on the left, you would also see <b><b>RAID</b> Status: Config Problem</b>.

</li>
<li>Clicking on <b>Launch WD <b>RAID</b> Manager</b> opens the <b>Drive Configurations</b> window. This time, however, you would see a <b>0</b> under <b>Capacity</b>. That&#8217;s because when one of the drives fails while in <b>RAID</b> 0 mode, as it did in this case, you immediately lose all the data. You would need to go to a data recovery company to possibly regain the lost data, if you didn&#8217;t have the data saved on another drive.
