105 <p>The first thing you have to do in order to use any piece of software is to download it. Unfortunately, sometimes even downloading software can be difficult. In fact, <b>Clonezilla-SysRescCD</b> is maybe one of the most difficult pieces of software to download, since there are three different files available - and you're still supposed to only download one of them.<br>
106 <br>
107 You not only need to choose between different files but also between direct download and torrent. This page will explain what torrents are, why torrent download is available and how the torrent can be used to download the actual file.<br>
108 <br>
109 In addition, if you use the direct download link instead of torrent, there is a risk that the file becomes corrupted during transfer, especially because it's very large. This page will also tell you how the integrity of the file can be checked before burning it to the disc.</p>

180
181 <p>The short answer: <a href="#torrent-i686">clonezilla-sysresccd-i686-"myVersion".iso</a>.<br>
182 <br>
183 And here comes the long answer:<br>
184 <br>
185 There are three editions of <b>Clonezilla-SysRescCD</b> available: <b>i486</b>, <b>i686</b> and <b>x86-64</b>. The difference between editions are the processor instructions in the assembly code of software included in <b>Clonezilla Live</b>. (The copy of <b>SystemRescueCD</b> is identical in all editions.)<br>
186 <br>
187 The <b>i486</b> edition only uses instructions which were introduced in Intel 486 or even older processors. Thus, it will even run on very old processors, including 486 itself. However, it doesn't support <a href="clonezilla.html#z_option" target="_blank">parallel compression</a> and is unable to clone very big partitions (about ten terabytes or more).<br>
188 <br>
189 The <b>i686</b> edition uses instructions which were introduced in Intel Pentium Pro or older processors. It will run on almost all processors used today and supports parallel compression. Cloning very big partitions is still impossible, though.<br>
190 <br>
191 The <b>x86-64</b> edition uses instructions which were introduced in AMD Athlon 64 or older processors. It supports both parallel compression and cloning very big partitions, but it doesn't run on IA-32 processors which are still widely used.<br>
192 <br>
193 The <b>x86-64</b> edition should be preferred if it runs. If not, the <b>i686</b> edition is preferable. If even the <b>i686</b> edition doesn't work, the <b>i486</b> edition is the last option.</p>

195 <H3><a name="download-arch"></a>Which is the architecture of my processor? <span class="hideprint">[<a href="#download-top" title="go to top of the page">^</a>]</span></H3>
196
197 <p>If you normally run GNU/Linux, download <a href="http://clonezilla-sysresccd.hellug.gr/edition">this script</a>, open terminal,<br>
198 <br>
199 mark the script as executable,</p>
200 <!--empty line-->
201 <p class="newcode">chmod +x edition</p>
202 <!--empty line-->
203 <p>and run it:</p>
204 <!--empty line-->
205 <p class="newcode">./edition</p>
206 <!--empty line-->
207 <p>If you run Windows, download <a href="http://clonezilla-sysresccd.hellug.gr/edition.vbs">this script</a> instead and double-click it. Note that the script doesn't work if Windows Script Host is disabled.<br>
208 <br>
209 Either script will immediately tell you which version of <b>Clonezilla-SysRescCD</b> is preferable.</p>

211 <!-- Torrent -->

214
215 <p>BitTorrent is a protocol that is used for sharing files. The most important difference between BitTorrent and direct download is that everybody who downloads a file via BitTorrent also uploads parts of the file while and after downloading it. That is, people who use BitTorrent are actually sharing the file with each other.<br>
216 <br>
217 The advantages of BitTorrent are:</p>
218 <ul>
219 <li><b>Saves bandwidth</b><br>
220 <b>Clonezilla-SysRescCD</b> is about 400 megabytes in size. Assuming 1000 people download it every month, HEL.L.U.G. needs 400 gigabytes of bandwidth monthly. By contrast, BitTorrent mostly uses the bandwidth of individual people (or their ISPs, to be exact).</li>
221 <li><b>Reliability</b><br>
222 A torrent file contains a hash of every part of the file. If any part turns out to be corrupted or even intentionally tampered with, the damaged part is simply re-downloaded. It's extremely unlikely that the resulting file is corrupted.</li>
223 <li><b>Speed</b><br>
224 When downloading the file directly, the server may limit the download speed. Download accelerators may improve the speed, but they make the download even slower for other people. However, when using BitTorrent, the file is downloaded from many people simultaneously and it is likely that your Internet connection sets the only speed limit. In addition, even if you can't wait and have to interrupt the download in the middle, you only need to download the missing parts afterwards - not the whole file.</li>
225 </ul>
226 <p>The disadvantage of BitTorrent is that most browsers are unable to download files via BitTorrent. That is, downloading a file via BitTorrent often requires special software.</p>
227
228 <H3><a name="download-torrentclient"></a>Using the torrent <span class="hideprint">[<a href="#download-top" title="go to top of the page">^</a>]</span></H3>
229
230 <p>Many users already have required software to use BitTorrent. First of all, check if you are using the <b>Opera</b> browser. It has a built-in BitTorrent client.<br>
231 <br>
232 In addition, most GNU/Linux distributions include a BitTorrent client like <b>KTorrent</b> or <b>Transmission</b>. You can test if your distro contains one simply by downloading the torrent and attempting to open it via double-click.<br>
233 <br>
234 Unfortunately, Windows doesn't come with a BitTorrent client. Windows users have to either download <b>Clonezilla-SysRescCD</b> directly or install a client, for example <a href="http://www.bitcomet.com/" target="_blank">BitComet</a>.<br>
235 <br>
236 If you have decided to use the torrent, proceed by clicking the torrent link. The web browser will ask if you want to open or save the file. Usually opening is easier, but if you decided to save the file anyway, continue by double-clicking the file.<br>
237 <br>
238 If the torrent client shows any prompts, follow them.</p>

243
244 <p>If you didn't use BitTorrent to download the file, it might have become corrupted during transfer. Corrupted copy of <b>Clonezilla-SysRescCD</b> may still work, but some functionality may be lost. In any case, it's best to notice corruption before burning the file to the disc.<br>
245 <br>
246 It is possible to download the whole file again in order to check if it's OK, but doing so is not a good idea. First of all, it requires a lot of time, especially if your Internet connection is slow. In addition, even if you notice that the copies of the file you have downloaded are different, you still don't know which of them is correct.<br>
247 <br>
248 Luckily, there are better ways to check if the file is OK. Some mathematical functions are able to take any input and create a fixed-length string called checksum or hash. These functions have been designed so that if the input is edited a bit, the resulting hash is completely different.<br>
249 <br>
250 The pre-calculated hashes of the files can be found next to the download links. The idea is that you're able to use hash calculator software in order to calculate the hash yourself and compare it to the pre-calculated one. If the hashes are different, the file is corrupted and you have to download it again. But if the hashes are identical, it's very unlikely that the file is corrupted. (Because there are finite number of possible hashes and infinite number of possible files, there are multiple files that share the same hash. However, it's very difficult to find out which files have a given hash.)<br>
251 <br>
252 The pre-calculated hashes have been calculated using the MD5 algorithm. It's the most popular hash algorithm around, and there are a lot of MD5 hash calculators available.</p>
253
254 <H3><a name="download-md5-windows"></a>Using Snap MD5 <span class="hideprint">[<a href="#download-top" title="go to top of the page">^</a>]</span></H3>
255
256 <p><a href="http://dan.hersam.com/software/snap-md5/index.html" target="_blank">Snap MD5</a> is a simple MD5 and SHA1 hash calculator. It's a closed-source, free Windows-only program.<br>
257 <br>
258 Copy the pre-calculated MD5 hash to the clipboard (double-click the hash and press Ctrl-C). Launch Snap MD5 and press <b>Browse...</b>. Navigate to the directory where you've saved the disc image and double-click the file. Wait a moment and <b>Snap MD5</b> will automatically tell you if the MD5 hashes match. If not, you have to download the whole disc image again.
259
260 <H3><a name="download-md5-linux"></a>Using md5sum <span class="hideprint">[<a href="#download-top" title="go to top of the page">^</a>]</span></H3>
261
262 <p><b>Md5sum</b> is a command line MD5 calculator that is included in virtually all GNU/Linux distributions.<br>
263 <br>
264 Copy the pre-calculated MD5 hash to the clipboard (double-click the hash and press Ctrl-C). Open terminal and navigate to the directory where you've saved the disc image of <b>Clonezilla-SysRescCD</b>. Write "md5sum" and a couple of the first characters of the name of the disc image:</p>
265 <!--empty line-->
266 <p class="newcode">md5sum clo</p>
267 <!--empty line-->
268 <p>Press Tab:</p>
269 <!--empty line-->
270 <p class="newcode">md5sum clonezilla-sysresccd-i686-"myVersion".iso</p>
271 <!--empty line-->
272 <p>Write "<b> | fgrep </b>" (space, vertical bar, space, fgrep, space):</p>
273 <!--empty line-->
274 <p class="newcode">md5sum clonezilla-sysresccd-i686-"myVersion".iso | fgrep&nbsp;</p>
275 <!--empty line-->
276 <p>Press Ctrl-Shift-V in order to paste the hash from the clipboard:</p>
277 <!--empty line-->
278 <p class="newcode">md5sum clonezilla-sysresccd-i686-"myVersion".iso | fgrep ISO_I686_MD5</p>
279 <!--empty line-->
280 <p>Finally, press Enter and wait until you get command prompt again. If you get something like the following output, the file is OK:</p>
281 <!--empty line-->
282 <p class="newcode">ISO_I686_MD5&nbsp;&nbsp;clonezilla-sysresccd-i686-"myVersion".iso</p>
283 <!--empty line-->
284 <p>If you don't get any output, the file is corrupted and you have to download it again.</p>
