class="wp-caption-text">The HTC Mozart Windows Phone</p></div><p>So what about the handsets?  Here is where I faced a real problem because without a shadow of a doubt, the iPhone and many of the current Android handsets are <strong>much</strong> better than the first batch of Windows Phones.  Phones such as the HTC Desire have been picked up by many of my friends because they&#8217;re just so good.  Indeed I&#8217;ve been very impressed by the build quality of HTC handsets in general.  The iPhone 4 though is also a fantastic piece of design and a wonderful handset I&#8217;d be delighted to have in my pocket.  It <em>had </em>to be a Windows Phone though so I had to make a choice.</p><p>My own carrier in the UK is Orange which gave me a choice of three.  The HTC Mozart, the Samsung Omnia 7 and the LG Optimus 7.  The LG was out straight away as I feel the plasticky buttons along the bottom of the screen are both cheap (in look and feel) and will eventually break.  Both the Mozart and the Omnia are excellent handsets but I wasn&#8217;t strictly tied to Orange so I had a look at the other carriers.</p><p>The HD 7 I felt had a very poor screen, it felt pale and washed out, so this was discounted early on.  The only other handset available was the HTC Trophy on Vodafone that feels like the poor cousin of the Mozart.  So sticking with Orange it was.</p><p>This is where the choice became <em>very</em> difficult and let me tell you why.  I had a Mozart for 10 days a couple of months ago when Microsoft sent me a review unit.  It&#8217;s a lovely phone, the gorgeous metal case and its smallish size make it an absolute pleasure to pick up and hold.  Because it&#8217;s not too big, with a 3.7 inch screen, it feels like a phone and not a computer too.</p><p>There is one major flaw with the Mozart though and it almost became a deal-breaker for me.  Because Windows Phone will let your switch off the phone simply by pressing and holding the power button, with no on-screen prompt to turn it off as well, this is <em>exactly </em>what happened <em>every time </em>I sat down to put my shoes on (I keep my phone in my front trouser pocket).  It is hugely irritating finding out your phone has switched off <strong>AGAIN </strong>just because you&#8217;ve sat down and leant forward!</p><p>This made me seriously consider the Omnia 7, one of only two Windows Phone handsets (and the only one in the UK) to come with an AMOLED screen.</p><p>This screen is an absolute joy.  It&#8217;s incredibly bright and the contrast is clear between blacks and whites.  But even this fantastic AMOLED screen isn&#8217;t without its problems.  At 4 inches it&#8217;s a little large for its resolution and a sort of fuzzy pixellation can occur around the edges of icons and the Windows Phone live tiles on the front screen.</p><p>It&#8217;s not noticable at a distance but for close work, which is what you do with a mobile phone most of the time, I knew that looking at these fuzzy edges and knowing that the operating system is really drawing a straight line, would annoy me.</p><p>There was also the build quality of the phone.  It&#8217;s made from solid-feeling metal but has a cheapness to the edging and the back that just could have been done better.  It&#8217;s just not up to HTC&#8217;s high standards and the large Samsung logo plastered across the front is too large to have to look at every day for the next couple of years.</p><p>Even so it was a close run thing.  The Mozart&#8217;s power button issue meant I had to consider the Omnia <em>very</em> seriously indeed (the Omnia&#8217;s power button is on the side), taking friends to my local Orange store to see it for themselves and reading review after review of it online (I&#8217;d already had a Mozart so knew what to expect with that handset).</p><p>In the end the HTC Mozart simply came out with more <em>pros </em>than the Samsung.  The only other choice was to wait and see what additional handsets came down the line in the next few months.  It was at this point though that I looked back at Windows Mobile 6.5 on my HTC Touch HD and knew I had to run away screaming and embrace a new handset whatever it&#8217;s foibles.</p><p>There can be no doubt that the second generation of Windows Phone handsets will improve on and fix these problems and be far better.  They will probably challenge the current crop of Android handsets, though whether anything will be a serious challenger to the hardware of the iPhone in the next few years is debatable at this point.</p><p>So there it is, laid out in bare metal for you why I chose my Mozart.  It can be such a difficult decision these days choosing a handset and the reason I wanted to write this up as an article is two-fold.  Firstly there may be some of you out there about to go through the same agony, but also <strong>because it&#8217;s just supposed to be a phone</strong>&#8230;  Why should this be a difficult choice?</p><p>There is no doubt that smartphones have made choosing handsets increasingly difficult, but I&#8217;m happy with mine now and it should be delivered tomorrow  :)  You can read my full in-depth review of the HTC Mozart and the Windows Phone 7 operating system at our sister site <a

My Samsung 1 TB hard drive was powered on 106 times and active for 814 hours since I build my new computer a few months ago.</p><p>How I know that ? I looked it up in the software <a
href="http://crystalmark.info/software/CrystalDiskInfo/index-e.html">Crystal Disk Info</a>. This software basically displays all kind of information about hard drives and Solid State Disks and two that are not displayed in every other of that type are the two I mentioned above.</p><p>It does display all the usual information as well. Begins with the hard disk temperature, serial number, transfer mode, drive letters and supported features among other parameters. Two of the aforementioned parameters are worth a closer look if you are experiencing crashes or slow downs.</p><p><span

It if goes to high it can lead to data loss and errors. The transfer mode can be interesting if you think that your hard drive is not as fast as it should be. Check the supported transfer modes of your drive and compare them to the one that is currently being used for it. It might very well be that it&#8217;s not the fastest available.</p><p>Crystal Disk Info is a portable application that is compatible to Windows 2000, XP, Vista and Windows Server 2003 / 2008.</p> ]]></content:encoded> <wfw:commentRss>http://www.ghacks.net/2008/06/29/how-many-hours-have-your-hard-disks-been-running/feed/</wfw:commentRss> <slash:comments>26</slash:comments> </item> <item><title>Ultimate Defrag</title><link>http://www.ghacks.net/2008/05/23/ultimate-defrag/</link> <comments>http://www.ghacks.net/2008/05/23/ultimate-defrag/#comments</comments> <pubDate>Fri, 23 May 2008 07:26:30 +0000</pubDate> <dc:creator>Martin Brinkmann</dc:creator> <category><![CDATA[Software]]></category> <category><![CDATA[Windows]]></category> <category><![CDATA[defrag]]></category> <category><![CDATA[defragmentation]]></category> <category><![CDATA[hard-disk]]></category> <category><![CDATA[hard-drive]]></category> <category><![CDATA[hd]]></category> <category><![CDATA[ultimate defrag]]></category> <guid

Looking a bit closer however will reveal another feature that has never been before implemented in defragmentation programs: The ability to move the files to other locations on the disk based on the highest possible performance. The outer locations of the hard drive are the faster ones while the inner locations tend to be slower.</p><p>When you start Ultimate Defrag for the first time you notice that is is displaying an image of your hard drive in the main pane and information i the left pane. You can select a different hard drive in the left pane or hit the analyze button to analyze the defragmentation level of the hard drive.</p><p>Once the hard disk has been analyzed one out of six methods to defragment and optimize the hard disk can be selected from the left pane. This includes the following options:</p><p><span

Sorts files and folders according to last access dates, modify dates and file creation dates.</li><li>Volatile: A variation of the Recency optimization. Will order folders last modification data and files alphabetically</li><li>Auto: The program uses its own optimization algorithm to defrag the hard disk and optimize its performance.</li></ul><p>The user can select specific files and folders that should receive the best positions on the hard disk to achieve the best performance possible. This can be for instance the Windows directory, a game, dynamic link libraries or applications. On the other hand files and folders that do not require the best performance can be selected to be placed in the slower sectors of the hard drive. This includes archives, images and backup files.</p><p>The help file of Ultimate Defrag is excellent. It gives an explanation of hard disk performance at the beginning, explains all the settings and functions in a non-geeky way and even provides examples of how to optimize computers based on usage, say gaming, office and home.</p><p>The Ultimate Defrag Free <a
href="http://www.freewaregeeks.com">version</a> is available at Freeware Geeks. I would like to mention that I&#8217;m not a lab and I do not have the possibility to check the performance before and after the defragmentation scientifically. My computer is relatively new with not enough files to test the new performance. It does make sense however that this could indeed increase system performance.</p> ]]></content:encoded> <wfw:commentRss>http://www.ghacks.net/2008/05/23/ultimate-defrag/feed/</wfw:commentRss> <slash:comments>16</slash:comments> </item> <item><title>Microsoft HD View</title><link>http://www.ghacks.net/2008/03/18/microsoft-hd-view/</link> <comments>http://www.ghacks.net/2008/03/18/microsoft-hd-view/#comments</comments> <pubDate>Tue, 18 Mar 2008 07:58:09 +0000</pubDate> <dc:creator>Martin Brinkmann</dc:creator> <category><![CDATA[Browsing]]></category> <category><![CDATA[Firefox]]></category> <category><![CDATA[ie]]></category> <category><![CDATA[Software]]></category> <category><![CDATA[hd]]></category> <category><![CDATA[hd view]]></category> <category><![CDATA[images]]></category> <category><![CDATA[microsoft]]></category> <guid

Those large images normally don&#8217;t fit the screen and the user may use the mouse to move around and zoom in or out of the image.</p><p>Since the images are of high resolution it normally does not decrease image quality that much when you zoom in. Only when you reach the limits of the image you will notice the usual effects when zooming in on images like a reduced sharpness of it.</p><p><span

/> notice that this type of media seems very fragile, if it&#8217;s scratched a little or<br
/> dirty, it won&#8217;t play. It seems less tolerent than DVD format. (Higher density!)</ul><ul>What &#8220;Backup HDDVD&#8221; is doing exactly?</ul><ul>This is a java based command line utility that decrypt video files (.evo) from a<br
/> HD DVD disk that you own, to your hard drive and you can play them back with a<br
/> HD DVD player software.</ul><ul>What are the system requirements to use &#8220;Backup HDDVD&#8221;</ul><ol>A Windows based system</ol><ol>A HDDVD disk drive</ol><ol>A HDDVD player software (like PowerDVD)</ol><ol>A HDDVD movie(s)</ol><ol>Java rutime 1.5</ol><ol>The possibility to access the content of the disk with a drive letter under windows.<br

/> decyption protocol. I have followed the freely available documents about AACS<br
/> Have a look at: www.aacsla.com<br

/> extract them.</ul><ul>How do you extract the &#8220;Title keys&#8221;?</ul><ul>I won&#8217;t explain it in detail. Read the AACS doc first. You will understand.<br
/> The title keys are located on the disk in encrypted form, but for a<br
/> content to be played, it has to be decrypted! So where is the<br
/> decrypted version of the title key? Think about it&#8230;</ul><ul>What kind of crypto algorithms are involved?</ul><ul>Standards algorithms:</ul><ul>ECC-160</ul><ul>ES-128</ul><ul>Look in the AACS doc for more details.</ul><ul>What is the TKDB.cfg file?</ul><ul>This is the Title key Database file. It holds the decryption keys for the movies.</ul><ul>What is the format of this file?</ul><ul>Field 1: SHA1 Hash of the VTKF000.AACS file on your HDDVD disk.<br

/> -A variable number of Title key, pipe delimited<br
/> You have a key number followed by the key value like:<br
/> 12-08A3DC61910280F2&#8230;<br
/> Key values are 128 bits long, so 16 bytes, or 32 hexadecimal characters long.</ul><ul> The TKDB.cfg file provided with your program is empty or incomplete, what can I do?</ul><ul>Well, you are on your own.</ul><ul>What do you think of the technical aspects of AACS?</ul><ul>The design is not that bad, but it&#8217;s too easy to have an insecure player<br
/> implementation somewhere. And just one bad implementation is all it needs<br
/> to get the keys! There will always be insecure implementations<br
/> of a player somewhere! And the &#8220;Revocation system&#8221; is totaly useless if you use<br
